Use More, Fewer, or the Same Number to Describe Groups
The purpose of this lesson is for students to use comparison language to describe the number of objects in groups.
In previous lessons, students identified and made groups with more, fewer, or the same number of objects as another group. They heard and made sense of comparison statements such as “There are more orange squares than green triangles.” In this lesson, students repeat and produce comparison language to describe the number of objects in groups.
- Action and Expression
- Compare groups of up to 10 objects.
- Use “more”, “fewer", and “the same number” to describe comparisons.
- Let’s use “more”, “fewer”, and “the same number” to describe groups.
Materials to Gather
- Each group needs three bags of 10 or fewer cubes:
- Bag 1: fewer red cubes than blue cubes
- Bag 2: more red cubes than blue cubes
- Bag 3: the same number of red and blue cubes
- Gather materials from:
- Less, Same, More, Stages 1
- Number Race, Stage 1
- Shake and Spill, Stages 1 and 2
- Math Fingers, Stages 1 and 2
- Pattern Blocks, Stages 1-3
- Picture Books, Stages 1 and 2

Teacher Reflection Questions
Students shared their thinking multiple times in this lesson. What have you noticed about the language students use? What support can you offer to students who struggle to communicate their ideas orally?
