Making Both Side Equal

Work out some numbers that make these equations true.

898+___= 900+____

224+___=_____+10

Give a range of possibilities for each equation.

Remember

The focus of this task is to regroup numbers mentally and remember that metal arithmetic often involves shortcuts. It might also be worth highlighting that = means equivalence and not “The answer is”.
