Codebreakers - Nearly Numbers Addition

A couple of codebreakers in the popular format. Students should solve the basic arithmetic to decode the answer to a bad joke.

There are 2 codebreakers - both involve the addition/subtraction of “nearly numbers” (that should ideally be rounded to the nearest 10 or 100 first before attempting arithmetic). The first codebreaker is relatively simple, the second is a slight step up in difficulty.

Both codebreakers are designed to be used with low ability groups to facilitate an understanding of place value.
