Sums Stacker is a fantastic app that will have your kids practicing their addition and subtraction facts without even realizing it. And they’ll have fun at the same time. The idea is simple – you have three sums at the bottom of your screen and a variety of numbers stacked on top of them in three columns. You must drag the different numbers from column to column until you have a stack that equals the sum it sits upon. You’re trying to complete the puzzle in the fewest number of moves and because it might take more than one move to get a number where you want it you’ve got to think your plan through before you start. There are two game modes – solve and race mode. In solve mode you are trying to solve five puzzles inthe fewest moves. In race mode you are solving puzzles and earning as many points as you can before you run out of time. You can play with easy or hard puzzles. My favorite part of the game is all of the different options for how you see the numbers. You can see them as numbers on a dice, as fingers on a hand, as numerals, as coins, in Spanish or even as a roman numeral. I’ve even left a few options off my list, there’s plenty to keep things interesting. In a future update I would love to see score tracking built in so the kids can keep track of how they are improving.
I really enjoyed Sums Stacker. It’s got charm and I love the twist it puts on practicing Math. This one is staying on my phone for an alternative to those flashcards that my kids “love” somuch.
