Version 1.0

Build fearsome confidence and awesome math fundamentals for your budding scholar! Players are challenged to tap pairs of spheres that add up to their current level’s number. Get them right, and the spheres disappear. Get them wrong and they freeze on the board creating a pile up on the screen. When 2 or more spheres rise above the top line, the round is over.

  • 20 levels to keep players challenged
  • High scores tracked for each level, and composite high score all levels
  • Players must master (by clearing at least 10 pairs) current level to unlock the next
  • See what happens when you master level 20!

We Make Educational Apps

As a parent volunteer in my son's 2nd grade classroom, I've been lucky to have an enthusiastic group of little beta testers. They're a diverse group of kids with a very wide range of math abilities. The advanced students try to unlock new levels. The students who are still building their foundational skills are thrilled to get New High Scores on the lower levels. Across the full skill range, there are challenges to keep any student engaged.

This game targets the Common Core Standard Math Standard for Grade 2 Operations and Algebraic Thinking: CCSS.Math.Content.2.OA.B.2 Fluently add and subtract within 20 using mental strategies. 2 By end of Grade 2, know from memory all sums of two one-digit numbers.
