Once a child can count to 10 and recognise all the number symbols you can begin to play with bigger numbers. Download and print a Hundred Square chart. Then point to the numbers and count. You can correspond this with counting on an abacus too. Then get your hands on or make some Flard cards. Then take tunes pointing to numbers on the Hundred Square and count them on the abacus and then build it with the flard cards. Make this a fun game and stop if they get tired. Although they won’t learn to count overnight they will gain a deep number concept and understanding of how numbers are made up. That is that 25 is 20 and 5 not 2 and 5. Have Fun!!!
