All about Year 3 fractions!

Year 3 have been learning about fractions. We have learnt that the number at the top of a fraction is called a numerator.  The number at the bottom is called a denominator. When you add or subtract fractions, the denominator always stays the same but the numerator changes. For example to add 1/5 to 2/5 –  1 + 2 = 3, so the answer is 3/5.

Today we have worked on fraction walls, which are blocks of different sections to help with division of fractions. We are given a wall and we have to write the answer in our books. Here is an example of a fraction wall (click to enlarge):

We learnt about fractions in Year 2 and it was quite easy because we dealt with quarters and halves. Now it’s getting harder because we learn about different denominators and doing different sums with fractions. We have lots of ways to help us with fractions, for example we can use circles or blocks to share the units out. We can also predict an answer in our heads before we work it out which is a good way of checking your answer. We memorise methods to help us work out sums.

We have worked together on our fractions in harmony and with respect – if someone gets the wrong answer we can help them to get it right. Here are some examples of our work (click on the images to enlarge):

We enjoy learning fractions because it helps us get our minds ready for harder maths in Year 4! It’s all about lifelong learning!
