Scaling Stories: teaching companion

Compare the product with a positive starting quantity by comparing its factor with one. Student pages include two diagnostic probes, a reteaching check, and the original exit ticket. The teacher copy includes the complete lesson preparation, teaching sequence, diagnostic responses, all original question guides, and updated rubrics.

Anonymous group code: __________   Date: __________

Diagnostic probes

Explain or draw your reasoning. Your teacher will use these responses to choose what to revisit.

d1. Before computing, predict whether 3/4 × 1/2 is below or above 3/4.

d2. Predict how multiplying 7/8 by 1 and by 4/3 changes the starting amount.

Check after reteaching

Complete this check independently after discussing the model.

r1. Without computing the exact product, compare 5/6 × 2/5 with 5/6.

Exit ticket

Complete both original exit questions independently. Use a drawing or explanation when asked.

e1. Calculate 3/4 × 1/2. Show a model or your reasoning.

e2. State the scaling rule for positive amounts.
