In a previous lesson, students told and acted out stories. Representing a story with objects may be more difficult because students have to understand the connection between the physical objects and the objects in the story. To assist students in making this connection, the first activity begins with the teacher acting out the story with representations of people such as toys or dolls and then transitions into students using counters.
Throughout the lesson, students should identify what the counters represent, based on the context of the story. The purpose of the lesson synthesis is to discuss how to use objects to represent addition and subtraction in a story (MP2).
- Represent addition and subtraction stories with objects.
- Let’s use objects to show what is happening in the story.
- 7 objects that represent people are needed, such as plastic toys or dolls. There are also images of people that can be cut out of the provided black line master.
- The playground work mat is printed in the student workbook and is also included in the black line master.
- Each student needs a bag of 10 two-color counters.
- Each group of 2 needs 10 two-color counters.
- Materials from previous centers:
- Subtraction Towers, Stage 1
- 5-frames, Stages 1 and 2
- Build Shapes, Stages 1 and 2
- Counting Collections, Stage 1
