Poor Roly! He seems to have gotten trapped in a retro video game. Have your kid help Roly return to the modern Knowhere by using his math fact knowledge to construct a staircase with number pairs that add up to ten. This game is perfect for helping your young learner master basic addition facts. Building Roly an escape path is also a great way to visually explain to your kid the process of decomposing numbers, an important part of addition and subtraction mastery.
