Students’ Assignment Page for the Culminating Activity

Essential Question of the Culminating Activity:
How do I use what I have learned about different forms of numbers to show how an F can affect my grade?

Paragraph Description of Culminating Activity:
Students will use data from a quiz situation to determine what effect an F has on a final grade. This activity requires students to
write ratios as fractions and then change fractions to decimals and percents using the methods (including setting up and solving
proportions) learned in the unit. Determining how F’s can affect a grade is a real-world situation that students can relate to in order
to use the skills and concepts that they have learned.

Steps or Task Analysis of Culminating Activity (include Graphic Organizers):
Students will work in groups of 4 to determine what effect an F has on a final grade.
1. The groups will designate assigned roles of facilitator, encourager, checker, and recorder to the members.
2. Everyone in the group will work together on each of the 4 given situations. The facilitator oversees that the work gets done while
the encourager pulls everyone into the work. The checker verifies the solution of the group and the recorder writes the solution on
paper. The recorder calls the teacher over to explain the solution.
3. Once the group has arrived at the correct solution, members must rotate roles within the group.
4. Groups are to complete the worksheet section for each situation and then graph the results, using a different color for each
situation.
5. Students answer the questions at the bottom of the assignment page.
6. The rubric will be provided to students prior to the activity. Students should use the rubric to assess themselves during the activity.
Playing Catch Up 3
Complete each student chart as we did the other day. Then graph the result of each student on the back. Use different colors to distinguish between
the different students.

Decision 4: Student Assessments

Plan for how students will indicate learning and understanding of the
concepts in the unit. How will you assess learning?

•   Short answer tests or quizzes
•   Student portfolios
•   Informal Assessment – See Summarizer Lesson 2 for sample questions to be used for informal assessment.
•   Formal student observations or interviews
•   Oral or written explanations of daily work
•   Culminating Activity
Decision 5: Launch Activities
Develops student interest and links prior knowledge. Provides the content
map and key vocabulary to students.

Literature Link: The Math Curse by Jon Scieszka and Lane Smith

1) Read this book to the students. This book is about a girl who wakes up one day to find that everything is a
math problem. In pairs, students will name as many different forms of numbers as they remember from the
story along with the situation in which they were used. They will have 2-3 minutes to do this in pairs. Each
member of the pair records the answers on his/her own paper. Then, they will “Give One, Get One” for 2
minutes. They will go back to their pairs and form a cumulative list. Discuss these as a class and reward the

2) Use the Content Map to give students the big picture of what they will learn in the unit and to
preview the vocabulary.

Decision 8: Differentiating the Unit
What accommodations will you make in order to meet the varied interests, learning
styles, and ability levels of all students?

An acceleration lesson is included for those students considered to be at risk. Performance tasks and word problems included
are from a variety of fields of interest. Students will be provided with choices from which they will select real world problems to
work. Actually, some of the tasks will be chosen from the list produced by the students during the Launch activity and the first
lesson. This unit contains auditory, visual, and kinesthetic activities to meet all learning styles. Scaffolding should be used
where appropriate.

Decision 9: Lesson/Activity Sequence and Timeline
What is the most viable sequence for the experiences, activities, and lessons in
order to help students learn to the best of their abilities? Put the Lesson
Essential Questions, activities, and experiences in order.
The lessons and activities in this unit are in Microsoft Word format and are numbered sequentially at the beginning of the
filename. Headers at the top of each page identify the lesson in which the page or activity is included. Also, the Content Map
gives an overall picture of the flow of the Unit. Since this is a new unit that has never been taught in 6 th grade there is no time
period listed on the lessons. This school year will be used to help gauge the pace of the new Georgia curriculum and
approximate timelines will be added at a later date.
Decision 10: Review and Revise
How will you review this unit in order to improve it prior to using it again or sharing it?
What criteria will you use to determine the need to make improvements?
List when you will conduct distributed reflection.

This unit will be used with hundreds of students during the 2005-2006 school year by 6th grade teachers as the new Georgia
Performance Standards are implemented. Teachers will give feedback during reflection meetings and during consortium
meetings at RESA.
The main criteria used to make improvements will be results from on-going formative assessment. Summarizers should provide
teachers with an indication of student understanding in order to review and revise this unit.
Distributed reflection will be conducted at the reflection meetings and during consortium meetings. I will ask that teachers keep a
portfolio of notes during this lesson to help make any adjustments needed. Also, samples of student work will be used to make
improvements in the unit.

Essential Question:           How can the same quantity be represented in different ways?

Review terms: fraction, decimal, percent, denominator, numerator, by using the vocabulary game
Acceleration/Previewing: “Hit or Miss” prior to the unit.
(Key Vocabulary) During the unit the term equivalent will be taught using a word map. Vinculum will be taught using
the Frayer Diagram.
Teaching Strategies: Use numbered heads to create pairs. Give each pair bags with 10 decimal squares in tenths and

Graphic Organizers)     a fraction not in simplest form but just as they see it (2/10), (20/100). Write these two fractions on
the board. Students will then cut the shaded part of their grids out and compare the quantity by
placing one on top of the other. Use the Word Map to define the term equivalent. Go back to the
fractions on the board and have them read their fractions aloud to each other while the other one
writes the number in words. Add this to the Word Map. Then have pairs brainstorm how the words
they have written would look if the amounts were written as decimals. Check understanding and
add this to the Word Map. Pairs glue their grids on the construction paper and label them in
fraction and decimal form.
 This is a good time to present the following analogy: I have students to describe how I am
dressed for school. I ask them to imagine what I would look like if I were working in my yard,
attending a baseball game, going to church, and attending an opera. After pairs discuss, we
list responses in columns on the board. Pose the following question: Have I changed who I
am or am I still “Miss Laurian?” I am still the same person; I have only changed how I look to
fit the situation. This is what we do with numbers.
Have pairs discuss how the fractions and decimals they have created are like dressing for various
occasions. Students work together to create 4 more equivalent amounts and write them in fraction
form and in decimal form. (Tenths should always go first for this activity.) They will trade
“denominators” and create 5 more and record as before. Use pairs squared to have one pair check
another pair’s work.
This is a good time to introduce percent. Ask them to take a look at one of the 100 decimal square
grids. Pose the following questions to pairs: If you were to place one penny in each of the squares,
how many pennies would you have? How many cents would that be? What if you only placed
pennies on 80 of the squares? How many pennies? How many cents? Have pairs write 80 cents
as a decimal the way we usually see it and then using what they have learned, write it as a fraction.
Introduce the idea that the vinculum (vin” cu’ lum) is a fancy name for the fraction bar. Students will
use the Frayer Diagram to learn this new word. There are several different ways to read the
vinculum, such as “out of” “divided by” “for every” or “per.” They think of a word and a picture that
reminds them of vinculum and record on the Frayer. (My example is “Van Column” and I imagine a
van carrying a column for a house on top of it. The column is lying down horizontally on the roof of
the van.) Go back to the fraction formed from 80 cents. Remind them that this fraction represents
80 out of 100 squares covered. Have pairs read the fraction to each other in three different ways.
If we read it as “80 per hundred” or “80 per hundred cents” then it makes “sense” that “per hundred”
means “per cent.” Record this on the Word Map in RED because it is very important that they
remember this fact. So, 80/100 is also the same as 80%. Students divide up their sheets with
decimal grids and go back and write the % to go with the decimals and the fractions. They trade
sheets and check each other’s work.

Summarizing Strategies: 3-2-1: Ones pick a fraction with a denominator of 10. Both students write:
Learners Summarize &     3 ways to write the quantity;
2 pictures to show the quantity is the same written in different ways; and
1 statement explaining why the same quantity can be written in different ways.
Write an additional page for the “Math Curse”.

Hit or Miss Directions:
Mary Kunzman and Mary Higham adapted this strategy from The Mailbox (1998) to promote knowledge of
content vocabulary. Select 10-12 vocabulary words for the game. Students copy the words from the word list
in random order somewhere on the gameboard as if placing ships on a Battleship game. Using numbered heads,
ones call out a set of coordinates. If twos have a word in that box, they say “HIT” and call out the word. Ones
then define the word, give an example of the word or use the word in a sentence according to the teacher’s
directions. If they are correct, the box gets crossed off, ones get a point, and it is twos’ turn. If incorrect or if
there is no word in the box, twos say “MISS” and then twos take a turn. The first person to get all of the points
wins – the loser will have all of his/her words crossed off.
Make copies of the grid to send home as homework so that parents can play with their children. Make extra
copies available for students to use when they complete their work or when more vocabulary practice is needed.
Ones: Pick a fraction with a denominator of 10. Tell your partner.
Each person must hand in a response:

Essential Question: How are ratio & proportion used to show relationships?
Activating Strategies: 3 Corners: Adaptation of 4 corners: See LFS Math 6-12 Activating Tab
(Learners Mentally Active) Place signs in 3 corners of the room. Each sign has one of the following terms on it: percent, decimal,
fraction. Each student draws a card from the hat with a number on it and writes the equivalent forms on
post-its and posts them on the corresponding sign. Have one student share responses from the signs with
the class.
Blowing Bubbles – LFS Math 6-12 Numbers and Operations page 10

(Collaborative Pairs;   during the lesson. Discuss the meaning of ratio, ways to draw, write, and say it. Use counters to model it.
Distributed Guided Practice;    Have students model sample ratios with counters in pairs. Relate ratios to fractions, equivalent fractions,
Distributed Summarizing;      and percents with the graphic organizer from Lesson 1.
Graphic Organizers)     Brainstorm where ratios are used in everyday life along with examples. Record on G.O. Give students
real-life examples such as batting averages, miles per gallon, miles per hour, recipes, calories per serving,
etc. Record these on G.O. and stress that the order that the ratio is written is important. This goes in the
“The Scoop” graphic.
Using Baseball Stats 1 handout students will write ratios that represent batting averages. They may bring
up the fact that batting averages are read as decimals. If so, tell them that they will convert the fractions to
decimals, but a ratio must be formed first. Refer to the essential question and stress that in this lesson we
are looking at the meaning of ratio and proportion and how they are used to show relationships.
Students should note that on this sheet, there is a column for decimals and percents. We already learned
that every number can be represented as a fraction, a decimal, and a percent. This does not change the
quantity that is represented – only what it looks like. (Ask them to tell their partners the metaphor used to
remember this – how we dress doesn’t change who we are, only what we look like.)
Notice that the handout uses simple batting statistics such as 5/10, 3/10, and 23/100 to relate writing these
as a decimal and percent the way they did in Lesson 1. Have 1’s write a matchbox summary of what the
ratios stand for and 2’s write a matchbox summary of why they can be written in different ways. Pairs have
two minutes to share their responses and check their partner’s accuracy.
Pairs get together with another pair (pairs squared) and discuss the following: How do you find the
unknown percent when given a ratio in fraction form with a denominator of 5, 10, 20, 25, 50, or 100? What
methods do you use? Are they all the same? Is one way any better than another? Come to some consensus
to prove your method works and record it to explain to the class. They have 5-7 min. (Before they begin
they must designate a timekeeper, a recorder, a mediator, and a speaker. Have speakers share with the
whole class (use overhead if needed). They go back to their pairs and discuss the following: What happens
when you are given a ratio such as 4/7 or 9/17. Give them about 5-10 min. to struggle with this. Suggest
that they go to their math notebooks and refer to their graphic organizer from a previous unit on comparing
fractions. Ask: How do you know if two fractions are equal? (cross products are equal) Given 12/18 and
2/3 show how you know by writing all of the steps. So if we were missing one of the numbers, say 2, then
we would have 12*3=n*18. Since we have solved simple equations before, how would you find out what n
is equal to? When you write two equivalent ratios, this means that you know that their cross products are
equal. Let’s go back to our word map from lesson 1 and review what equivalent means. So, if we write the
steps below the ratios, using a variable for the unknown, then all we need to do is to solve for the variable.
When two ratios are equivalent, this is called a proportion. If we have to find out what one of the numbers
in the proportion is equal to, we are “solving proportions.” How would you check your work?
Let’s record what we know about proportions on our G.O. for this lesson. Give some numerical and word
problem proportions and have students solve them and share with their partner. Samples are included.
After they have done a few through guided practice, take out whiteboards. Using whiteboards 1’s will write
the equation and 2’s will solve for 5 problems. Then switch roles for 5 problems. (These are numerical).
Then do the same for 10 word problems where they write the ratios and set up proportions and solve. Given
the proportion 3/7=n/22, what does this mean. Record on G.O.

Extending Thinking Lesson Planning Form
Essential Question: How do I know which form of a number to use?
Mini-Lesson: Carousel Chairs: Instead of moving around the perimeter of the room, students will be in groups of 4 and will change
seats after working one problem on each sheet. This can also be done by students staying in the same seat and passing
the sheets around in a circle. See attached for what should be on each sheet. Be sure to include questions as well as
problems.
Check student understanding by comparing answers from each group.
Task: Problem solving lesson: Use ROPES and the flipchart to have students solve problems involving various forms of
numbers. There should be an emphasis on the “P” – Plan. This is where students should look for clues in the problem
that tell them which form of the number is best to use and which form the final answer should be in. Students must be
able to explain why they worked the problem the way that they did and why they chose the form that they chose.
They will be working in small groups on this task.
Summarize/Sharing: Students will share their solutions and reasons with the whole class. This is a great time to point out that all of them
did not work the problem the same way. They should, however, be able to explain their thinking and why they chose
to use the form of the numbers that they chose. The answer must be in the correct form.
Assignment: Massed Practice:
Each group is given authentic problems dealing with situations of choice. Students will work individually and then get
together to check their work. Problems can be found at:

Each student will work the following two problems:
