Activity 1: Put Together Dots on 5Frames (10 minutes)
Narrative
The purpose of this activity is for students to find the total number of dots on two 5frame cards. Students may use the structure of the 5frame to help them find the total number of dots. For example, if there is a 5frame with 4 dots and a 5frame with 1 dot, students may notice that if you move the 1 dot to the 5frame with the 4 dots, the 5frame would be full. Although using the structure may help some students, many students will count all the dots on both cards to determine the total number of dots. Both strategies demonstrate an understanding of adding two groups together to find the total number of dots.
MLR8 Discussion Supports. Invite students to begin partner interactions by repeating the questions, “How many dots are there altogether?” and “How do you know?” This gives both students an opportunity to produce language.

 Dots on 5Frame Cards (05)
Required Preparation
 Cut out a set of cards for each student.
Launch
 Groups of 2
 Give each student a set of cards.
 Display a 5frame card with 4 dots and a 5frame card 1 dot.
 “I have two 5frames with some dots in them. How many dots are there altogether? How do you know?” (5 dots. I counted them. I showed 4 and 1 on my fingers and counted them. If I moved the dot to the other 5frame, it would be full. That means there are 5 dots.)
 30 seconds: quiet think time
 1 minute: partner discussion
 Share responses.
 “I have 5 dots together, so I’m going to write a 5 on the line. Now my sentence says ‘There are 5 dots’.”
Activity
 “It’s your turn to play this game with your partner. Each of you will flip over one 5frame card. Then, figure out how many dots you have together and write the number on the line.”

 Display a 5frame with 2 dots and a 5frame with 5 dots.
 “How many dots are there altogether?”
 “If we add together the 2 dots and 5 dots, we have 7 dots. 2 and 5 is 7.”
 Write “2 and 5 is 7.”
 Invite students to repeat chorally in unison 1–2 times: “2 and 5 is 7.”
Activity 2: How Many Apples? (10 minutes)
Narrative
The purpose of this activity is for students to count 2 groups of images to find the total. Students recognize the 2 groups as well as the total when both groups are put together. Students repeat addition language such as, “5 apples and 3 apples is 8 apples” (MP6).

Activity 3: Introduce Roll and Add, Dots (25 minutes)
Narrative
The purpose of this activity is for students to learn stage 1 of the Roll and Add center. Students count to find the total number of dots in two groups of images. After they participate in the center, students choose from any stage of previously introduced centers. The recording sheet is printed in the student book for this activity. There is a blackline master available for students to use during centers in future lessons.
