Fractions is a new topic that we have not covered yet in Y5, so doing the above activities will be excellent to recap.
We will be moving onto new work on fractions on Friday and next week.
IF you are really confident with fractions and the above is too easy, I suggest you visit the site I will link below.
Watch lesson 1 (but if you read the instructions above the video you will see there is a playlist of many other videos on fractions you can watch). This uses the Maths Mastery approach and includes activities on the video itself. The powerpoints for all videos are available on the page as well. These videos are excellent - but definitely go more 'in-depth.'
