You know StudyPad makers of Splash Math and eduPad makers of iTooch Math. Now welcome Padstar to the SAFK family. Today we have all seven of their math apps free for teacher appreciation week. That's one app free for each day of the week hence our first GFAOTW. These are regularly $3.99 each so save $28 and your sanity since these apps teach as well as reinforce core math skills for elementary school students.
In Match-Up Math, children must match tiles with equal values in order to make them disappear. For example, 2+2 can be matched with a tile that says 4 or one that says 3+1.
When all the tiles are cleared, the player moves on to the next level. The difficulty increases as the player progresses and the backgrounds of the boards change, which gives the player a nice sense of progression. Someone in iTunes described it as "Mahjong Math." (I've never played Mahjong.)
