I walked into a 2nd grade classroom Thursday to find the students busily engaged in math workshop.  Several students were working with iPads and playing what looked to be an addictive math game.  I sat myself down and asked them to show it to me.  The app, Numbers Logic Puzzle, is a Candy Crush-like game for making ten. Players swipe neighboring number tiles that add to 10, causing the tiles to disappear and new tiles to fall into place. When I got home, I downloaded it on my iPad and gave it a go myself.  Wonderfully addictive! My only complaint about the free version is that I don’t particularly like the ads for their other apps that pop up.  They are not bad enough to prevent me from recommending the app, but I just wanted you to be aware of them.

While I was at the app store, I decided to look for other free apps for making 10. It’s such a critical skill that kiddos need all the engaging practice they can get.  I found a couple of others.
Make 10+, which is also free, features comic book style graphics that will be very appealing to students. The game basically involves selecting a tile from the bottom that pairs with the tile on top to make the target sum.  As players advance through levels, the tiles on the bottom rise up more quickly.  If the bottom tiles reach the top tiles, it’s game over. The app is called Make 10+, because it’s so much more than making 10.  Using the settings, you can change the sum, so you can differentiate play for a student’s individual number.  If, for example, a student is working on combinations for 5, they can play using 5 as the target sum. Another great feature is the ability to play using dots in place of numbers.  This is perfect for developing subitizing skills and offers representational support for students who aren’t quite at the abstract (symbolic) level.  Overall, this app gets an A+ from me!
Franklin’s Friends of Ten is another freebie with catchy graphics and music.  I’m not exactly sure about the connection between Ben Franklin and the complements of 10, but I think students will enjoy the fireworks.  Two features I like about this app.  First, the number line representation shows students the symmetry in the complements of ten, emphasizing patterns and leading to generalizations (the higher one addend is, the lower the other needs to be).  Second, this app actually shows the friends of ten as an equation.

These are good ones.  Go forth and download!! 🙂
