Distributive axiom through geometric patterns

Created by

The distributive axiom can seem rather abstract to elementary students, so teaching it through concrete geometric patterns can help to clarify the concept. In these slides, the distributive axiom is approached by treating the multiplier as the number of rows or columns and chopping the line of objects (multiplicand) into two groups (addends). It allows students to see where the addition and the multiplication come into play, and it relates the distributed math problem to the undistributed one. I

Distributive axiom applications

The distributive axiom is the basis for the multiplication algorithm involving factors with multiple digits, and it is also the fastest way to do mental math. While it is increasingly added to elementary math texts, the coverage is often sketchy, misplaced, and poorly integrated. In addition, no obvious reason is given for learning it. This slide set is designed to help walk students through steps needed to use the distributive axiom of multiplication with respect to addition. It also covers whe
