Number Pyramids helps your kids exercising their basic addition and subtraction skills by the dragging & dropping of numbers into pyramid bricks.

Number Pyramids is recreating the well-known number walls that one can find in many textbooks and homework assignments. With Number Pyramids you will get

- an unlimited number of exercises
- 3 levels of difficulty (small, medium and large pyramids with 6, 10 and 15 blocks each)
- optional number placements (at the bottom or at random places)
- immediate positive or negative feedback
- intelligent error correction (a wrongly-placed number is removed)
- intelligent help (an unplaced number is placed into the correct block)
- four different themes

For parents and teachers:

- all learner actions have a small sound attached to it. You can thus watch your kid from afar and know about his/her progress and achievements.

- Initially, Ive built this app for my seven year old daughter (then in her 2nd grade), and she already spent hours on it. Many improvements originated from her (the butterfly awards, the sound mechanism).

- By spending the dollar, you keep the app free from ads and in-app purchases. We also have a very strict privacy policy, which means that we do not collect any personal information from you or your kid, neither from the app nor the support page at mathdistrict.com

Number Pyramids 1.6 is available for the iPad and now requires iOS9 or later.
