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 drew the shape correctly, they keep the card. The partner with the most cards at the end of the game wins. Shape cards include triangles and quadrilaterals.

One student secretly picks a shape card and describes the shape to their partner, who draws it based on the description. Together they compare the drawn shape to the shape on the card. If the shape is drawn correctly, the partner who has drawn it keeps the card. The partner with the most cards at the end of the game wins. Shape cards include triangles, quadrilaterals, and hexagons.

One student secretly picks a shape card and describes the shape to their partner, who draws it based on the description. Together they compare the drawn shape to the shape on the card. If the shape is drawn correctly, the partner who has drawn it keeps the card. Shape cards include polygons, with a focus on quadrilaterals.

One student draws a rectangle and chooses to tell their partner either the area or the perimeter of their shape. Their partner draws the rectangle based on the description. They earn two points if their rectangle matches their partner's rectangle exactly and one point if it doesn’t match exactly, but matches the clue given. The partner with the highest score at the end of 8 rounds wins. This game encourages students to use multiplication fluency to think about rectangles that could be more difficult for their partner to draw.

Before playing, students organize the cards into three piles, according to their backgrounds. On each round, students draw from a different pile of cards:

• round 1, rectangles without a grid
• round 2, rectangles on a grid
• round 3, rectangles on a coordinate grid

One student secretly picks a shape card from the pile for that round and describes the shape to their partner, who draws it based on the description. They earn two points if their rectangle matches the shape on their partner's card exactly and one point if it doesn’t match exactly but matches the clue given. The partner with the highest score at the end of three rounds wins.
