Dexteria Dots - Preschool Math

This app presents good ways to learn the concepts of adding and subtracting and how they can be thought of as combining and separating. Unfortunately, at the harder levels, it just assesses the students on their ability to memorize rather than to know addition or subtraction. A student may also simply click a bunch of random numbers until they get the correct answer. I would want to use this for my child before they start learning addition and subtraction in written form, but there are other ways to promote these concepts than paying $3 for this app.

My son, who has been struggling to learn fact families, likes this app. It is helping him to have better number sense. He is in 3rd grade, is very bright but also has a very slow cognitive processing speed. My daughter, who is 4.5, loves the app. It is sort of good for such a young child, but definitely can be a challenge. Hard for little hands to use more precise gestures that you need.

Love the first 2 levels, but once it gets into solid colors, it's confusing. It goes from being a counting game to a memory game which isn't helpful for educators. It's a great start, but the advanced bits need to be revised.
