Objective: Students will understand basic fractions by creating pizzas with different toppings.

Materials: Pizza dough, toppings (cheese, pepperoni, olives), paper plates.

Procedure:

1. Introduction: Explain the concept of fractions briefly.

2. Activity: Divide students into groups and give each group a pizza dough. Ask them to create pizzas with different toppings to represent fractions (e.g., 1/2 cheese, 1/4 pepperoni).

3. Collaboration: Have groups present their pizzas and explain the fractions they represent.

4. Reflection: Discuss as a class how the activity helped them understand fractions better.

This approach combines hands-on learning with collaborative group work, aligning with both Piaget's principles and the goals of play-based education.
