HSA-SSE.A.2

Use the structure of an expression to identify ways to rewrite it. For example, see x4 – y4 as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2).

MP2

Reason abstractly and quantitatively.

MP6

Attend to precision.

MP7

Look for and make use of structure.

Warm-up

10 minutes

Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

Today's warm-up provide a "mixtape" of sorts to give kids a small amount of review daily that goes a LONG way toward retention of concepts.

Task #2 is a good one to spend time looking at student work - often, students forget to apply the exponent to everything inside the parentheses, and this question is designed to catch and remediate that.
