Unit 4 Review
One problem from every lesson
Every move in Unit 4
Here's all of Unit 4 on one card. Change subtraction to adding the opposite. Expand the parentheses. Sort and combine like terms. Factor out the GCF when you want groups. And check that two forms are equivalent by simplifying both.
| Lesson | The rule |
|---|---|
| Lesson 1, Hand it out, take it back | Change it to adding and multiplying. |
| Lesson 2, Combining like terms | Sort the piles, and flip every sign when you subtract a group. |
| Lesson 3, Expanding | Hand it to every term, then combine. |
| Lesson 4, Factoring out the GCF | Pull out the greatest, and check by expanding. |
| Lesson 5, Fraction and decimal coefficients | Common denominators and lined-up decimals. |
| Lesson 6, Equivalent expressions | Same value every time. |
