Mr Harris Maths 9th Jan 2015 Ratio and Probability

0

Welcome back to the new school term.

This week, we have spent three days looking at ratio, proportion and scale.  Some of the ideas covered are below:

If you are following a recipe with your child, you could ask them questions like:

“This recipe is for 4 people. If we need 240g of flour for 4 people, how much would we need for 6 people? 7 people?”

The children have some SATs questions for homework.

On Friday, we introduced a new area: probability. We have explored the language of probability – certain, likely, unlikely etc – and have begun to represent probability as a fraction, percentage or decimal. We have begun to explore number spinners and probability and have drawn a probability number line.

Next week we will spend two more lessons on probability and then move on to perimeter, area and volume.
