Division by Heart

Introduction

Division by Heart focuses on division facts with whole number quotients from 1 ÷ 1 through 100 ÷ 10. Representations used include number bars and area models. Both partitive and quotative division are modeled in the number bar representations.

Deck Visualizations

Deck 2 uses number bars to model quotative division. Students enter a missing factor in a multiplication problem.

Deck 3

Deck 3 uses rectangles to represent an area model for multiplication. Students enter a missing factor in a multiplication problem.

Deck 4

Deck 4 uses number bars to model partitive division.

Deck 5

Deck 5 uses number bars to model quotative division.

Deck 6

Deck 6 uses rectangles to represent an area model.
