About Tens and Ones
Long rods stand for tens and small cubes stand for ones. Your child counts the rods, counts the cubes and puts them together into one number, such as 3 rods and 4 cubes for 34. Tricky wrong answers, like 43 with the digits swapped, keep everyone alert.
How to play
- Count the rods of ten, then the single cubes.
- Put the tens and ones together and tap that number.
- With a keyboard, choose an answer with the keys 1 to 4.
