Maths | Rounding & Compensating

Rounding and compensating a number is taking numbers, observing the ones as well as the tens and then moving them to the highest or closest ten number.

For example, seventy-eight (78). The eight only needs two more to make eighty but if we subtract eight to make seventy, eight is a bigger number than two, therefore adding two would be quicker to making a tidy number.

For maths, the objective was to solve six maths equations using the strategy rounding and compensating and to visually show how to solve the maths questions on a DLO. On this slide, it also includes a number line to help show the maths.
