Math Prep — Week 7

Solving One- & Two-Step Equations: Find X

Final week  •  algebra  •  fill-in + circle-one  •  two test versions

Name: Date: Version (A / B):
How to use this test. This is the last check-in of the course — you have been building to this. Every equation here comes apart in the same two moves, so slow down and take them one step at a time.
VERSION A

Test A

PART 1

The First Step

Before you solve anything, decide which move comes first. Circle the correct first step.

1.In the equation 2x + 1 = 9, what do you do FIRST? (circle one)
a) Subtract 1     b) Divide by 2
2.Circle the first step for 3x − 2 = 10:
a) Add 2     b) Divide by 3
3.Circle the first step for 5x + 5 = 20:
a) Subtract 5     b) Divide by 5
4.True or False: You should remove the constant (the number alone) first. Answer:
5.Which part is the variable term in 2x + 1? Answer:
Clarify — Undo the equation in the reverse of the order of operations: peel off the added or subtracted number first, then deal with the number that is multiplying x. The variable term is the piece that has an x attached to it.
PART 2

Solve the Equation (Step by Step)

Follow the two guided steps. Whatever you do to one side, do to the other.

Equation: 2x + 2 = 8
6.Step 1: Subtract 2 from both sides. What is 8 − 2? Answer:
7.Step 2: Now you have 2x = 6. Divide by 2. What is x?   x =
Equation: 3x − 1 = 8
8.Step 1: Add 1 to both sides. What is 8 + 1? Answer:
9.Step 2: Now you have 3x = 9. Divide by 3. What is x?   x =
Clarify — Two moves, always in the same order: (1) cancel the constant by doing the opposite operation on both sides, then (2) divide both sides by the number in front of x. The steps are laid out for you — just carry out the arithmetic.
PART 3

Solve It — Find X

Now do both steps yourself. Solve for x.

10.2x + 1 = 5  →  x =
11.2x + 4 = 10  →  x =
12.3x + 1 = 7  →  x =
13.4x − 2 = 6  →  x =
14.5x + 5 = 30  →  x =
15.2x − 4 = 0  →  x =
Clarify — Same recipe every time: move the constant across first (opposite operation), then divide by the coefficient of x. When you get an answer, plug it back into the original equation to check that both sides match.
PART 4

Word Problems

Turn the words into an equation, then solve it.

16."Twice a number plus one equals 5." Write the equation. Answer:
17.Solve the equation you wrote in #16. Answer:
18."Three times a number minus one equals 2." Write the equation. Answer:
19.Solve the equation you wrote in #18. Answer:
20.How confident do you feel about algebra now? (1–5) Answer:
Clarify — Translate word by word: "a number" is your x, "twice" means 2×, "three times" means 3×, "plus"/"minus" is the constant, and "equals" is the = sign. Once the equation is written, solve it with the exact same two steps you used above.
VERSION B

Test B

PART 1

The First Step

Before you solve anything, decide which move comes first. Circle the correct first step.

1.In the equation 2x + 3 = 11, what do you do FIRST? (circle one)
a) Subtract 3     b) Divide by 2
2.Circle the first step for 4x − 1 = 7:
a) Add 1     b) Divide by 4
3.Circle the first step for 3x + 4 = 10:
a) Subtract 4     b) Divide by 3
4.True or False: You should divide first. Answer:
5.Which part is the constant in 2x + 1? Answer:
Clarify — Undo the equation in the reverse of the order of operations: peel off the added or subtracted number first, then deal with the number that is multiplying x. The constant is the number standing on its own, with no x attached.
PART 2

Solve the Equation (Step by Step)

Follow the two guided steps. Whatever you do to one side, do to the other.

Equation: 2x + 4 = 10
6.Step 1: Subtract 4 from both sides. What is 10 − 4? Answer:
7.Step 2: Now you have 2x = 6. Divide by 2. What is x?   x =
Equation: 3x − 2 = 7
8.Step 1: Add 2 to both sides. What is 7 + 2? Answer:
9.Step 2: Now you have 3x = 9. Divide by 3. What is x?   x =

Reflection — Looking Back on 7 Weeks

Which type of problem felt easiest this week? Which one made you slow down and think? Name one thing about math you can do now that you could not do in Week 1.

How to run the Week 7 equations check-in — and how to review it without an answer key

1. What this test measures

This is the final week. Every question rests on one idea: a two-step equation comes apart in the reverse of the order of operations — undo the +/− first, then undo the ×. Part 1 checks that the student can name the first move, Parts 2–3 check that they can carry it out, and Part 4 checks that they can build an equation from words. Watch which of those three stages breaks down; that tells you where to spend time. There are two parallel versions (A and B) with identical structure and different numbers — use one as the test and the other as a re-take or warm-up.

2. Run it with gradual release: I do → we do → you do

3. Using the Clarify hints

Each Clarify box coaches method only — "undo the constant first," "translate word by word" — never the numeric answer. Let the student attempt the part before reading it. A strong habit: ask them to tell you the strategy before they look, so the method becomes theirs rather than the paper's.

4. Common slips to watch for

5. Reviewing it together — without an answer key

This sheet has no key on purpose. You do not need one:
