These twelve self-checking puzzles help students connect multiplying decimals with powers of 10 written in standard and exponential form. This hands-on math activity also reinforces the concept of "moving the decimal point" rather than counting zeros to prepare students for decimal division.

The twelve puzzles use the same digits so students must focus on the placement of the decimal points. This self-checking math activity works well as a math center and/or an independent activity for differentiation.

Students love the self-checking aspect of these puzzles. After assembling all 12 puzzles, students flip them over one at a time to see if the pictures on the back match. The immediate feed-back motivates students to find and correct their mistakes.
