By visually illustrating the mental subtraction strategy of compensation by using moving base ten blocks and a bin my students where able to better understand how answers are adjusted by adding back or subtracting more and therefore compensating for the rounding which made the question easier.

Download includes a double sided worksheet based around the PowerPoint teaching.
