Do your students get excited when you tell them it's time to estimate decimal sums and differences? Of course they don't.
But they will if you use this fun, Safe Cracker worksheet!
Students can become world famous safe crackers! Your students will use the clues and their math skills to help crack the safes, in order to claim the prizes found inside.
Students are given three "clues", which are estimation problems with decimals, including addition, subtraction, and word problems. The answers become the numbers in the safe combinations. When the three clues are solved, the safe is cracked! There are a total of 15 problems, but they are grouped into 5 "combinations", so your students will look at this as a 5-question assignment.
The rewards include: a yellow diamond, priceless artwork, the keys to a classic car, an Amazon gift card, and a rare baseball card!
