# Lesson 12

Make Dot Images

## Warm-up: How Many Do You See: Dots in Different Colors (10 minutes)

### Narrative

The purpose of this How Many Do You See is to allow students to use subitizing or grouping strategies to describe the images they see.

### Launch

• Groups of 2
• “How many do you see? How do you see them?”
• Flash the image.
• 30 seconds: quiet think time

### Activity

• Display the image.
• 1 minute: partner discussion
• Record responses.
• Repeat for each image.

### Student Facing

How many do you see?
How do you see them?

### Activity Synthesis

• Display last image.
• “What are the 2 parts that you see? What is the total?” (I see 2 red and 3 yellow. 2 and 3 are the parts. There are 5 altogether.)
• “We have been looking at dots in How Many Do You See throughout the year. In the next activity, you will get to make your own groups of dots.”

## Activity 1: Make Your Own Dot Images (10 minutes)

### Narrative

The purpose of this activity is for students to highlight compositions and decompositions of numbers to 5. Students create a set of cards with dot images by coloring in dot arrangements and drawing their own arrangements of up to 5 dots. Students will use the cards they create in the next activity.

Engagement: Internalize Self-Regulation. Provide students an opportunity to self-assess and reflect on the dot cards they made. For example, they can verify that they used at least 2 different colors to color the dots.
Supports accessibility for: Organization, Attention

### Required Materials

Materials to Gather

Materials to Copy

• Dot Image Cards

### Required Preparation

• Create a set of cards from the blackline master for each student.

### Launch

• Give each student dot cards and access to colored pencils, crayons, or markers.

### Activity

• “You are going to get to make your own groups of dots. Use at least 2 different colors to color in the dots to help your partner see the different parts in the total. There are some blank cards. On these cards, you can draw your own groups of dots and color them in.”
• 7 minutes: independent work time

### Activity Synthesis

• “Pick your favorite dot image. Tell your partner why it is your favorite and what parts you see inside of the total.”
• “In our next activity, you will share your dot images in a small group. What do you need to do to be a good group member and help everyone learn?”

## Activity 2: How Many Dots Do You See? (15 minutes)

### Narrative

The purpose of this activity is for students to identify more than one composition and decomposition of numbers to 5. Students use the dot image cards that they created in the previous activity to play their own version of the “How Many Do You See?” routine in small groups.

MLR8 Discussion Supports. Synthesis: At the appropriate time, give groups 2–3 minutes to plan what they will say when they present to the class. “Practice what you will say when you share your dot image with the class. Talk about what is important to say, and decide who will share each part.”

### Required Preparation

• Each student needs the dot image cards from the previous activity.

### Launch

• Groups of 4
• “You are going to use the dot cards you created in small groups, just like when we do our How Many Do You See warm-up. The first person will hold up one of their dot cards for their group members to see. The rest of the group members will have time to think. Then they will share how many dots they see and how they see them. Take turns sharing your dot images.”

### Activity

• 8 minutes: small-group work time

### Activity Synthesis

• “Work together to choose one dot image to share from your group. Choose a dot image that the members of the group saw in different ways.”
• Invite each group to share their dot image.

## Activity 3: Centers: Choice Time (20 minutes)

• Bingo
• Geoblocks
• Find the Value of Expressions
Students will continue to choose from these centers in upcoming lessons. Keep the materials from each center organized to use each day.

## Lesson Synthesis

### Lesson Synthesis

Display dots as pictured, or choose two student-created cards:

“What is the same about these dot images? What is different about them?” (They both have the same total. They both show 5 dots total. They are different because they show different parts. One shows 4 and 1 and one shows 3 and 2.)
