Questimate: A fun app that really makes you think about sizes and weights. Answer questions like: "How many yoga mats would be as long as a minivan?" and then you make your guess and find out how close you are. You gain lives by making good guesses, and lose lives when you guess is too far off.
Geoboard: Remember the geoboards we used to use to illustrate shapes and lines by hooking rubberbands around the pegs? This is the same type of geoboard, but you never have to worry about your rubberbands breaking or flying across the room!
Flash to Pass: This is a flashcard practice app that allows you to practice addition, subtraction, multiplication and division.
Number Pieces: A great app for visualizing place value. You can break your ten sticks into ones, or hundreds into tens. When you create a new grouping of ten you can snap the ten ones together into a ten stick, or snap a grouping of ten tens into a hundred block.
BupplePop: See how many bubbles you can pop by selecting the products. Although the free version only has multiplication, this can be a fun way to get your practice in.
