• 30 seconds: quiet think time

### Activity

• Display image.
• 1 minute: partner discussion
• Record responses.

## Activity 1: Introduce Can You Draw It, Grade 1 Shapes (20 minutes)

### Narrative

The purpose of this activity is for students to learn stage 1 of the Can You Draw It center. Students describe and draw two-dimensional shapes. One partner chooses a shape card and describes it. The other partner draws the shape based on the description. If the student draws the shape correctly, they get to keep the card.

### Required Materials

### Launch

• “We are going to learn a new center called Can You Draw It. One partner picks a card without showing it to their partner. They describe the shape on the card so their partner can draw it.”
• Display one of the cards.
• “How can we describe this shape?” (It has four sides. The top and the bottom are longer than the sides. It has square corners.)
• “After the shape is drawn, partners compare shapes. If the partner drew the correct shape, they keep the card. Take turns describing and drawing shapes.”
