The purpose of this activity is for students to count to find the total number of images in 2 groups. Each problem shows one group of organized images and one group of scattered images. In the Activity Synthesis, students discuss how they kept track of the images they counted and continue to hear the language "___ and ___ is ___."

• Invite previously selected students to share how they found the total number of balls for the problem with 3 soccer balls and 6 footballs.
• “How does _____ know that they counted all the balls?” (She crossed them off as she counted them, and they are all crossed off.)
• “There are 9 balls. How many soccer balls are there? How many footballs are there?”
• “3 soccer balls and 6 footballs is 9 balls. We can say ‘3 and 6 is 9.’”
• Write “3 and 6 is 9.”

The purpose of this activity is for students to count to find the total number of images in 2 groups. In this activity, both groups of images are scattered. In the Activity Synthesis, students discuss different ways the images could be counted in order to find the total. When students count scattered images they need to be strategic and count in an organized way to make sure that each image is counted once and only once (MP6). 

If students count each image more than one time or don't count some of the images, consider asking:

• “Can you show me how you counted the circles?” As students count, ask “Which circles have you counted? Which circles do you still need to count?” 
• “What could you do to help you remember which circles you have counted already?” If needed, ask “How could crossing out the circles help you make sure you count all of the circles?”

• Display the image of 3 black circles and 5 white circles.
• Invite previously identified students to share how they counted to find the total number of circles.
• “Some of us counted all of the black circles first. Some of us counted the black and white circles together. We all found the same total.”

The purpose of this activity is for students to choose from activities that offer practice writing numbers, counting to find the total of 2 groups, and describing and building with shapes.

Students choose any previously introduced stage from these centers:

• Roll and Add
• Math Libs
• Match Mine
• Tower Build

• “What is one thing that you got better at during centers today?”
