About Number Pyramid
Bricks are stacked into a pyramid, and each one holds the sum of the two bricks under it. One brick shows a question mark instead of a number. Your child adds for gaps higher up and takes away for a gap in the bottom row.
How to play
- Find the brick with the question mark.
- Add the two bricks below it, or take its neighbor away from the brick above.
- Tap the answer, or press key 1 for the first choice, 2 for the second.
What your child practices
- Adding pairs of numbers
- Finding a missing part
- Linking adding and taking away
- Reasoning with numbers
