Mr G has produced a really helpful fraction sheet full of games that you can play to help you develop your understanding of fractions. Have a play!
As a school we use White Rose resources to support our teaching of maths. They produce a number or resources for parents too.
I would recommend that you look at the 'Maths home learning' section. Once on this page select, 'Maths Year 5 (v3 schemes) from the drop-down menu and then choose the Autumn term. If you click here you will go straight to the blocks of learning that I follow. By clicking on each block you will access a series of videos that your child can work through.
There are also free downloads that look good. Do have a look.
