Before doing this children should be confident with counting in the teens. Subtraction develops by taking ten from a teens number.
2 Once again lots of oral work needs to be done with these and children will probably need the aid of a number line to begin with. 1260 Adding or subtracting ten Page 3 MathSphere Adding ten Join the kites to the correct ratties 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 6 5 9 2 7 11 15 12 16 19 17 1260 Adding or subtracting ten Page 4 MathSphere Adding ten Join the kites to the correct ratties 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
