NOW problem – in back of your
Aleks notebook. When you are
finished get out your notes.
1.Choose one word to describe in your
own words: term, constant, variable,
coefficient
2. Create an expression and identify a
term you DID NOT define.
Objective:
The student will be able to solve one-step
equations using inverse operations.
What is KEY here? Any words you do not
know yet?
Levels of Understanding
4 - I can teach the topic of one step equations
USING inverse operations or apply it to
something we have not learned.
3 – I can SHOW steps and solve one-step
equations without errors.
2 – I can solve one-step equations without
showing my work.
1 – Huh?
Think of some words that are opposites.
For example, what do you think of as the
opposite of word below.

ALGEBRA
Scary, isn’t it?!
ONE STEP EQUATIONS
An equation is like a balance scale
because it shows that two
quantities are equal.
What you do to one side of the
equation must also be done to the
other side to keep it balanced.
In Mrs. Koontz’s head… Please
watch and write down the
questions I ask myself.
x + 3 = 17
Let’s ask the questions together
now…
13 = y – 4
Really think on this one…How am I
going to move that 9? Talk
through it with your neighbor.
9 + n = 21
Try it on your own…Keep asking
yourself those questions.
18 = 5 + x
