This app is amazing for teaching place value and addition and subtraction with regrouping. My special education students are really starting to understand how to regroup because of this app. When they get stumped on a problem, I can ask them how they would do it on the base ten blocks app and they can apply the same skills on their papers. The visual of combining and breaking apart for regrouping has been especially helpful for my students. I can ask them what happens when you regroup on the app and they remember that it breaks into ten pieces or combines into one group. They are prone to making little mistakes when setting up a problem and I love that the app will show the problem at the bottom so they can check their work. The company has been great to work with, responding to comments and suggestions.
The snapping to grid is great! Makes it easy to quickly demonstrate various multi-digit #s. Like that when you write it stays on the screen until erased. Paired with iPad’s new feature of recording screen as you use the app is a bonus. Well done!
For example, the one blocks don't automatically snap together so sometimes we unwittingly put one on top of another, hiding the one block. This problem should never happen, in my opinion. But when it does, there's no undo so it's difficult to figure out where the hidden block went. The blocks are so small, even on a ten inch ipad, it happens more than you'd think. Better than nothing I guess.
Great app. The is a bug or maybe something that I don’t understand. The decimals show tenths as 0.01 instead of 0.1. And the blocks for ones and hundredths seem to be switched.
Eraser on the draw tools is more like an undo button. Doesn't allow the user to choose what to erase. Can't do double digit multiplication greater than 21x30- it would be helpful if the size option was available on the factor track page as well. Then I could squeeze higher numbers in.
