problem_activity: Narrative
The purpose of this activity is for students to learn a new variation of stage 2 of the Math Stories center. Students use two-color counters to act out and tell stories involving addition or subtraction with the background mats. Students use objects or drawings to represent and solve the story problem that is told to them by their partner.
After they participate in the center, students choose from any stage of previously introduced centers.

Required Preparation
Each group of 2 needs 10 two-color counters.
Gather materials from:
Bingo, Stages 1-3
Math Fingers, Stages 1-3
Math Stories, Stages 1 and 2
Subtraction Towers, Stage 1
5-frames, Stages 1 and 2
Counting Collections, Stage 1
Launch
Groups of 2
Give each group of students 10 two-color counters and a set of background mats. Give each student a recording sheet.
“We are going to learn a new way to do the Math Stories center.”
Display the background mat with a playground.
“This time I need to think of a story to go with the background mat. I also need to think of a question to ask at the end of the story.”
“My story is: 6 kids were playing on the rings. Then 2 of the kids left to go play on the slide.”
“What question can I ask at the end of my story?” (How many kids are still playing on the rings?)
30 seconds: quiet think time
Share responses.
“Now I’ll tell my partner my story and ask the question.”
“You can use the background mats to help you act out the story if it is helpful. You can also draw a picture on the recording sheet. Write a number to show the answer to the story problem.”
“Take turns telling story problems to go with the background mats. Remember to include a question for your partner at the end of your story problem.”
Activity
8 minutes: partner work time
“Now you can choose another center. You can also continue playing Math Stories.”
Display the center choices in the student book.
Invite students to work at the center of their choice.
8 minutes: center work time
If time, invite students to choose another center.

Activity Synthesis
Invite 2 students to share different story problems about the same background mat.
As each student shares, record the action with words and numbers and an expression. For example: “3 and 6” and “
\(3 + 6\)
”.
“What was the same about the stories? What was different?”
