The purpose of this activity is for students to learn Stage 3 of the Which One? center. Students lay the shape cards face up in rows. One student chooses a shape, without telling their partner or removing the card. Their partner asks “yes or no?” questions about the shape’s attributes. Students work with triangles, quadrilaterals, and hexagons.

• “Which types of questions were most useful to ask when you were trying to guess which shape your partner chose?”

The purpose of this activity is for students to learn Stage 2 of the Can You Draw It? center. Students describe and draw two-dimensional shapes. One student picks a shape card, without showing their partner. They describe the shape to their partner, who draws it based on the description. Together they compare the shape that was drawn to the shape on the card. If the student has drawn the shape correctly, they keep the card. The partner with the most cards at the end of the game wins. Students work with triangles, quadrilaterals, and hexagons. Before playing, remove any cards that do not show a triangle, a quadrilateral, or a hexagon.

• Display a shape that was more challenging for students to describe.
• “How could we describe this shape?”
