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. A strip is cut into four pieces with widths 1, 1, 1, and 5 cm. Can every piece be called one fourth of the strip?

d2. A square is cut along a diagonal into two triangles. Is each triangle one half even though neither looks like a rectangular strip?

Check after reteaching

Complete this check independently after discussing the model.

r1. A whole has three pieces; two are small and one is large. What must change before all three can be called thirds?

Exit ticket

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

e1. Three unequal pieces are each one third. Is that correct? Choices: Yes / No.

e2. Explain the mistake in calling any one of four unequal pieces one fourth.
