This activity can be played with a Breakout Box, modified Breakout Box, or modified into an Escape Room activity with envelopes or pictures cards. This activity has a high level of student engagement. Students in 4th, 5th, and 6th graders will practice both word problems and computations for whole number division and whole number by decimal division. The activity is self-checking.
