3. Build Your Explanation

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

Claim: You first make the divisor a whole number using equivalent division.

Evidence: Students explain you move the decimal in the divisor to make it whole (6.3 to 63) and move the dividend the same way, naming 18.9 as the dividend and 6.3 as the divisor.

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