Mr Cooke’s Maths 23rd Jan – Equivalent fractions and decimals

0

This week in maths we have continued to compare fractions using a fraction wall. We have been finding equivalent fractions and the children were able to see patterns in the fractions that were equivalent. They created lists of fractions e.g. 1/3, 2/6, 3/9, 4/12 … and were able to describe what was happening to the numerator and denominator as the sequence continued. Where they found it more challenging was when they had to match pairs of equivalent fractions from a group of mixed fractions. For example seeing that 5/10 = 1/2, 3/12=1/4 and 3/9=1/3.

We then moved on to marking fractions on a number line between 0 and 1. The children were taught to count the number of intervals (jumps) between 0 and 1 in order to establish what fraction the number line was increasing by. They completed various challenges such as the example below:

Finally we started to relate the fractions on the number line to decimals. This occurred naturally when one child suggested that the middle of the line was also 0.5. On Thursday the children used laptops to play ‘Fruit Splat’ – a game where you have to select the equivalent decimal to the floating fraction. Click on the link below to play:
