Algebra 1 Lesson Plan

Name: Danny Murray and Andrew Finger
Date: 23/10/08
Class time: 14.30
Class level: Junior Certificate Maths
Topic: Algebra 1

Aims:
1. To introduce the concept of algebra and it's uses.
2. To give the students and understanding of the basic mechanics of algebraic
maths.
3. To develop the students confidence to speak aloud before their class.

Objectives: Students will be able to:

1. Add and subtract known algebraic terms.
2. Convert a worded problem into an equation.
3. Simplify equations containing groups of equivalent variables.

Previous Knowledge:
 Some possibility of algebra in primary school.
 Length by width for area.
 Counting real objects fingers etc.

Anticipated problems:
a+b = ab, difficulty translating from worded language to maths.

Solutions:
Explain using everyday objects that don't mix along with many worked through
example problems.

Opening:
A little speech:

"Hands up who likes pizza?
Hands up who likes long division?
I hate long division too. (probably a surprise)
Unless I'm dividing pizza into long slices.
Then division is actually useful, I don't mind it so much.

This is algebra. Adding different types of things, not just numbers.

Implementation:
Episode One: Demonstration + Fascination = Motivation

Here's why algebra is great and you should ring your friends and tell them about it:
Algebra is a very powerful tool that can be used to predict the future.
Do example: Drop a pen from a meter. Ask students to write down how long that
took.

while they do this, flip over white board:

(sqrt(2s)/g)=t    (<-you don't need to understand this yet)
0.141 seconds     (magic!)

From a meter, algebra can be used to find the answer very accurately.
Give out class worksheet now.

Episode Two: Unlike Terms, debunking a+b=ab, simplification,
(a) Work through example 1 on worksheet:

1 + 1 - 1 = 1 (yes)
Emphasize that this is not algebra.

1 bear +1 bear - 1 bear = 1 bear (so?)
Emphasize that this is basic algebra.

1 man + 1 bear – 1 pig = not ManBearPig
Emphasize that this is algebra and it's rule one.

"This is maths, not biology. Manbearpig is dangerous."

(b) Work through example 2 on worksheet:

Emphasize that pirates and ninjas never mix.

Episode Three: Worded problems
 Work through example 3 on worksheet with class:
 Consecutively ask 4 students to fill in each term of the equation from the
worded problem.
 Ask them to finish it off themselves and go around to check their answers.

Episode Four: Testing students understanding with questions
If there's any remaining time, let students start the homework questions.
Let the students work and watch out for any confused faces or non-moving pens.

Episode Five: Variables and constants (differences and understanding)
HOQ1-what is a variable? What do you think of when I say that something may/can
vary?
The students will be asked this question, and asked to think what a variable is.
They will be able to understand it a good bit them selves, but to help them along, I
will use the length of a spring as an example of a variable.
HOQ2-what springs to mind when I say that something is a constant?
Students will be asked this question, and helped along in their thought process by the
teacher, who will encourage their efforts to answer the open question.
To help them reach their understanding of a constant, I will illustrate how the length
of a mobile phone is always the same, ie. Contant length.

Episode Six: Algebra Jargon
Students will be introduced to words used often when working with algebra, like
Term, Expression & coefficient.
Simple equations and problems will be run through on the board, and the phrases used
to get the students to get to know them and recognise them.

Closing:
To finish the class, an acetate with all that was covered will be placed up on the OHP,
and run through. The students will have their work sheets handed out to them, and
homework assigned from them.

Resources:
White Board Flip Chart with prepared text.
11 x Algebra 1 Handouts
1 x Algebra 1 Teacher Notes
Chalk and blackboard.
Ruler
Acetate with prepared notes and OHP
