## Teacher Review

One of the main reasons we really liked using this game is that it leaves a lot of the thinking and learning up to the user. This is a game that develops skills of logic and hones the skill by mode of repetition.

In this app, the numbers go from 11-20.  A number between 11 and 20 pops up in the centre of the screen and the learner’s mission is point out all of the numbers that make up the number. So, for example, if the number is 11, we must point out “11+0, 0+11, 10+1, 1+10, 9+2, 2+9, 3+8, 8+3...” and so on. The larger the number the more combinations there are. .

The great thing about this is that the numbers that the learner chooses from are set in a circle which makes it easier to see the associations between numbers. This is very interesting as the creators of the app have effectively created their own abacus-style representation in order to develop counting skills. Once the app has been completed in number order during the first play, all the numbers are set at random so that the game can be played over and over again.

Number bonds is the foundation of numbers as it develops the logic between the numbers and how they come about. Counting is simply a human invention to represent the world around us. If we can communicate the basic concept of that and build on it, kids will find it much easier to relate to mathematics. This app does this in a fun way, as the illustrations, the sounds and the colours make it very easy to engage with the numbers. As a result, kids will begin to form number associations in their own minds.

We would advise to have an adult in the first round of playing just to hone-in on the concepts and the counting however, once the basics have been learnt and understood kids can play by themselves.

Overall, this is a very nice app that kids will enjoy playing (and learning) with!
