4B4 – week ending 20th December

We continued work on Unit 3 – Numeracy, with rounding to significant figures. This is under Library – Number – Estimating and Accuracy – Rounding Decimals as well as Significant Figures. We also did some work on percentages especially non-calculator work. This was followed by work on compound areas – i.e. shapes made up of two or more shapes joined together, and then onto calculating the circumference of a circle.
