In maths, Star Ninja and Bubble Bobble have begun learning to use the maths strategy of rounding and compensating. Basically it is borrowing off one number and adding it to another (to make a tidy number) making it faster to add together.
In this basic example we have taken from 2 from 45 and added it to the 38 to make the equation
45 + 40 = ___
Have a go at this example:
145 + 56 = ____ What do you need to "take" to make a tidy number?
Bubble Bobble then celebrated their newly learnt strategy by playing a little calculator golf!
