Math Search 

Math Search is a great game that will help kids practice their math skills while playing a game. The objective of the game is to solve five calculations and find the answers in a grid full of numbers. The answers can be found horizontally, vertically or diagonally and you mark them by highlighting the numbers with your mouse and then pressing the "Check" button. You get points for every right answer. Moreover, there's a timer that starts counting when you start the game, and the faster you find the answers, the more points you get.

The user interface of the game is simple but attractive. The game has sounds and suitable, but a bit annoying music. You can mute all the sounds or regulate the volume from the settings menu. The game can be played online or it can be downloaded, and you can also play it in full screen. Once the game is finished, your score can be published on three popular social sites, so you can compete with your friends.

In short, Math Search is a simple but great game to make kids practice math while having a good time playing for free.
