How to add in year 1
Adding
To add, we use Numicon, number lines and 100 squares.
See examples below:
8 + 4
Using Numicon
Get a 8 piece and a 4 piece. Put the 4 piece against the 8 and count the number of holes, encouraging children to begin counting at 8 rather than 1.
Number line
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Start on 8 and jump forward 4 to land on 12
100 Square
Find the start number (8) and jump forward and down to the next line, counting 4 jumps. Land on 12. 100 squares are also used to add and subtract 10 by going up or down the columns.
