Decimal Rounding

LI: To solve addition problems with hundredths by changing one number into a whole number.

For this maths task this week, my group and I learnt how to use an efficient strategy called decimal rounding to solve decimal equations quicker.

To use decimal rounding, you should subtract from a decimal to round it and whatever has been subtracted should be added to the other decimal number. That will make it easier to add or subtract those numbers.

We used decimal rounding to solve various different decimal equations. I enjoyed this task and found it easy and quick to do because I am familiar with rounding but I was able to experiment with decimal equations.
