Diagnostic probes

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

d1. On identical wholes, compare 3/8 and 5/8. What stays the same and what changes?

d2. One strip is twice as long as another. Can comparing their shaded counts of eighths alone compare actual lengths?

Check after reteaching

Complete this check independently after discussing the model.

r1. Using the same-sized whole, compare 6/8 and 4/8 and state why.

Exit ticket

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