Fluently multiply and divide within 100, using
strategies such as the relationship between
multiplication and division (e.g., knowing that 8 × 5
= 40, one knows 40 ÷ 5 = 8) or properties of
operations.

Variables in math
2/13
Introduce linear equations
with one variable where
the coefficients are
represented by variables
and write the answers to the following
questions:
1. Work out the birthday equation for
each of you.
2. Explain how the fruit equation
always works out to 4.
3. Plug in the variables to make 9 seats
in the coffee shop.
4. My number is 935, what is my
birthday?
2/14/17
Set up linear equations with one variable
where the coefficients are represented by
variables, solve by using the inverse
operation
Warm-up
The goal of solving an equation is to find the
value of the variable.
To do this isolate the variable on one side of
the equation using Inverse Operations.
Inverse operations “undo” each other!

TOGETHER you will
create an Anchor Chart
that defines variables
and what steps you
would use to solve the
equations

Practicing Variables
When Algebra
problems have an
unknown variable
you must isolate the
variable to the
solution side. I will
do the first one
Now, we will do
this one together.
Solve linear
equations with one
variable where the
coefficients are
represented by
variables.

So, we know variables, now what?
We need ot be able to simplify.
So, write this information in
your IN so you can refer
4 + 7m + 2 + 6m
back to it.

Warm up - simplify the following
-4 - 10v -2V2 -7v + 10
1 + 9c - 7c -8 -8c
What if we throw in a second variable? 1b + 9c - 7c + 8b
Can we solve these?
Why/why not?
What can we do?
What must we have in order
to get an answer?
