Why do we bother with BIDMAS?
Learning Targets
Beginning
To be able to explain a method for rounding decimal numbers to a specific number of places or significant figures.
Developing
To be able to demonstrate how to estimate the values of calculations involving positive numbers greater than one.
Mastering
To be able to calculate the limits of accuracy for numbers given to the nearest whole number.
Resources
Beginning
Rounding (from Ten Ticks 4, 3, page 7-8)*
Tarsia - Rounding to nearest 10, 100, 1000
We will start by looking at rounding numbers the nearest 1, 10, 100 or 1000. If you need some help take a look at this video: Rounding
We now move on to looking at rounding numbers to a set number of decimal places. If you need some help take a look at this video: Decimals Points and Significant Figures (first half).
