Okay, you're teaching your kids how to do two and three column addition.... WHAT A SNOOZE! I promise you, this is going to be fun! Here's how it works: you've taught your students about regrouping/carrying in multi-column addition, and they've done a few problems and you want them to have a little more experience with it while doing some deep thinking. This is the activity for you! This collection of "ink blot addition puzzles" will engage your students in a completely different way, because

This is Max Forstat; she owns a building which has 4 apartments per floor. There are 6 floors in the building. She decides to number the apartments from 1 to 24, starting from the ground floor. Apartments 1 through 4 are on the first floor, 5 - 8 on the second, and so on. How would you figure out which floor each apartment is located? This activity gets students involved in performing division with and without remainders, and then using the remainder to determine the floor and location of the ap

This is a collection of 34 different hexagonal subtraction/additional/logic puzzle cards (hence, the title above) which uses 5 rows containing clues that have to be figured out by moving around the puzzle in different directions.

Seriously, the basic puzzle is simple: take the disks which are numbered 1 - 6, and arrange them on the board so that each side adds up to 9. However, things get very interesting when you find out that you can re-arrange the 6 numbers to add up to 10, 11 and 12. But it gets better than th

These are among my favorite "hands on" puzzles to have my kids learn addition facts, or do remediation for those who are having problems "catching on." There are 10 different "bean puzzles" which can be cut out and glued to a paper plate. Number them 1 - 10 so kids can keep track of which ones they've completed (1 is the easiest, 10 is the most tricky.) Students complete the puzzle by taking dried kidney beans (or bean shaped counters) and distributing them in each pan so that two pans add up to
