Lesson objective: Students will apply their knowledge of using models to represent division and multiplication.

This lesson provides an opportunity for students to apply their knowledge and understanding of using models to a mathematical situation. Students are asked to determine how cookies can be shared equally among friend.

Key Concepts students will use:

Skills students will use:

- representing division and multiplicatiton through the use of arrays, equal groups, number lines, repeated addition or repeated subtraction models.
- students will practice with the inverse property of multiplication and division.

Students engage in Mathematical Practice 1 (make sense of problems and persevere in solving them) as they model multiplication and division using diagrams, arrays, number lines, drawings, etc.
