                     Stage 1 – Identify Desired Results

  Established Goals:


   Students will use representations to model addition and subtraction. (a) Use counting G
   strategies to find out how many items are in two sets when they are combined. (b)
   Build number combinations up to 10 and for doubles to 10. (c) Use objects, pictures,
   numbers, or words to create, solve and explain story problems for two numbers that are
   each less than 10.



  What understandings are desired?


   Students will understand that…                                                                    U
   …counting can be used to determine the number of elements in sets when they are combined.
   …they can model addition and subtraction by building number combinations and doubles up to
   10
   … they can use models to create, solve, and explain addition and subtraction story problems for
   two numbers each less than 10.




  What essential questions will be considered?


   1. How can counting be used to determine the number of items in two sets                          Q
   when they are combined?

   2. How can you use building number combinations and doubles to represent
   models of addition and subtraction in story problems

     Audience: The people who want order fruit                                                                 nce Task
     Situation: The KDG Fruit Company will fill orders for fruit in combinations to 10 Orders may be any       Blueprint
     combination of two kinds of fruit to a capacity of 10 (i.e. 3 apples and 7 oranges; 5 oranges and 5       for each
     apples).                                                                                                  task (next
     Performance: Required number of jobs will be placed in a hat. Students will pull jobs from the hat to     page)
     determine where they will work. Jobs will be customers, packers, inspectors, supervisors. Customer
     will complete order forms. Customers must know number combinations and doubles to 10. Packers
     will read orders and package the fruit according to what is on the order form. Packers must know how
     to recognize numbers 0-10, and count form 1 to ten. Inspectors will check each package of fruit for
     quality control to be sure that orders are filled correctly. Inspectors must know all of the previously
     mentioned skills. Supervisor must know everyone’s job and keep everyone on task. Students will
     switch roles so that everyone will have the opportunity to do each job. Once all orders have been
     filled. Students must complete inventory by writing the total number of fruit used in the task. Then
     they will subtract the number fruit used to complete their orders. Students will write a subtraction
     problem using the inventory data. Once task is complete students will record their experience in a
     journal and share writings with the class.
     Standards and Criteria for Success: The students will…
     …use knowledge of number recognition from
     …match items sets
     …combine sets to represent a number
     …differentiate when to add and when to subtract.

Consider the WHERETO elements:
   Stage 3 – Plan Learning Experiences and Instruction
1. Do you have enough jelly beans to share with seven friends if you have 5 blue and 3 yellow? H
2. How can we use addition to find the answer? (TPS). After recording responses teacher will L
demonstrate what addition means (introduce addition vocabulary and symbols). W
3. Help students think of other real life examples and practice writing number sentences with a
partner. E-2
4. Provide independent practice as homework. :Count the number of forks and spoons at your
house. Write 3 number sentences and draw the picture to match.
 5. Review by going over homework and using POD: There are some bears in the sandbox. Some
monkeys come to play. How many bears could there be in the sandbox and how many monkeys
could there be in the sandbox if there are 7 animals in the sandbox in all? Tell students to start
with what they know(7animals in all). Suppose you had 1 bear. How many monkeys would you
need to have 7 animals in all? Show number sentence 1 + ____= 7. Help students count to find
out that the number is 6 (students may use counters if they need to). Write in the number
sentence. Continue with 2 bears, 3 bears, 4bears,etc. to 6 bears; then switch to one monkey,
2monkeys, 3 monkeys…….6 monkeys. How many bears would there be? E
6. Provide independent practice as homework: Give students counters to take home. 5of one color
and 5 another color. Tell student to help them to write all the ways to make 6. _____+_____= 6. E
7. Review by going homework assignment.
8. POD: What number am I thinking of if I have one set with 3 and another set with 2? Students
may use what ever method they choose to find the answer. Students discuss how they chose
their answers. Find the rest of the sums for 5.E
9. Divide class into 3 groups. Assign one group to solve a problem by acting it out. Assign another
group to solve a problem by drawing a picture. Assign the third group to solve the problem by
