An equal-groups drawing shows a collection partitioned into groups with the same number in each, making visible the two factors: the number of groups and the number in each group. It connects the structure to repeated addition and a multiplication equation for whole-number totals within 100, while distinguishing equal from unequal groups; arrays may clarify the structure, without extending to larger or more generalized products.
To represent equal groups, draw the same number of objects in each group.
Example: Draw 3 equal groups of 4 stars.
There are 3 groups, and there are 4 stars in each group.
Write the repeated addition:
Write the multiplication equation:
So, 3 equal groups of 4 make 12. The groups must have the same number of objects; groups with different numbers would not be equal groups.
