3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: I let a variable stand for the unknown number of gems.

Evidence: Students choose a variable (such as n) for the unknown gems, build n + 8 = 20, and connect 'plus 8 more' to + 8 and 'equals 20 total' to = 20.

Reasoning: This evidence connects the definition of equation to the mathematical claim.
