Mummy Math: Adding Decimals

Decode a secret word using decimal addition in this Halloween-themed math puzzle. Designed for fifth and sixth graders, this worksheet requires students to add three-digit decimals.

Students start by completing 12 addition problems that include three-digit numbers with decimals. Once complete, students look at each problem to see if its answer is listed at the bottom of the page in the secret word code. If it is, learners write the letter from that problem in the blank box above the solution. When all the blank boxes are filled in with letters, they should spell the secret word.
