4th Grade Lesson: Fraction Circles: Pizza Sharing

Students get an introduction to the use of variables and decomposition and extend their understanding of fraction equivalence by solving problems involving equally shared pizzas

## Resources for Fraction Circles: Pizza Sharing

computer-based

### Activity Summary

This activity has three phases. First, students independently solve an equal sharing problem on paper. Second, the teacher leads a discussion eliciting different solution strategies for solving the problem from the students. For each solution, the teacher walks students through what a corresponding programming solution would look like. Third, the students code equal sharing solutions involving a loop.

### Math Connections

Students extend their understanding of fraction equivalence by solving problems involving equally shared pizzas.

### CS Connections

Students get an introduction to the use of variables and decomposition in problem solving. Students use their knowledge of repetition when decomposing a problem.

### Topics

• Sequence
• Repetition
• Decomposition
