When I first found this app, I really liked it and was using it a great deal with my first graders at the beginning of this school year. It shows a ten frame and you click on numbers that make pairs of 10. A SUPER important skill for kids to be fluent with in K and 1. It gives kids tons of practice with combinations of 10 and a visual image to support them. At the beginning of the year, I thought this was the only thing the app did and I still loved it. About two months ago, I was talking about combinations of 100 with a colleague and she suggested I use this app for some third graders who were struggling with this idea.
|The most basic setting for Find Sums. Students practice combinations of 10 with a visual image of a ten frame to support their developing understanding.|
I had no idea what she was talking about until she showed me the settings menu on this app. It opened up an entire menu of possibilities that I didn't know existed. All you do is touch the i in the upper right hand corner and you get this
Let's take a look at some of the different settings
|This is sum total of 100 with an apple model. This student has clicked on 75 and 25 which is a very important combination of 100. When they are ready to move to the next problem, they just click on any number. This is a skill I spend a lot of time working on in grade 2 and the beginning of grade 3 for kids who still need more practice.

The best part about this app is that it is a fairly fast game yet still gets at important ideas and provides the right amount of support. It is a great time filler between transitions or as kids finish other work with only a few minutes remaining in a class period.
I only have access to a few iPads so I also use some of these free computer games on the classroom computers and the smart board to work on similar skills.
