Grades: 2‒5

Bunny Times is a multi-level Sketchpad game that features compelling graphics and animation. It presents a visual and interactive approach for children to learn, with understanding, the multiplication facts 2 × 2 through 12 × 12. Multiplication statements are represented in the context of carrots in a field, with a statement like 3 × 4 shown as four rows of three carrots each.

In the early levels of the game, children control the hops of a single bunny, telling it how many carrots are available to eat. In later levels, teams of bunnies hop in unison, and children are able to split the teams in ways that make it easier to determine the total number of carrots.

Bunny Times fosters the development of a variety of multiplication strategies, including skip counting (computing 3 × 4 by counting 3, 6, 9, 12), “adding on” (if 7 × 6 is 42, then 8 × 6 is 6 more, or 48), and distributing (8 × 4 = (5 × 4) + (3 × 4)).

OBJECTIVES

In this game, students will:

- Gain abundant practice in learning the multiplication facts 2 × 2 through 12 × 12.
- Explore multiplication using a rectangular array model.
- Skip count to solve multiplication problems.
- Use an “adding on” approach to solve multiplication problems.
- Use the distributive property to solve multiplication problems.
- Decide for themselves which multiplication strategy is most appropriate for a given problem.
- Develop fluency of multiplication facts through acquiring multiple strategies for thinking about multiplication.
