Hi everyone! Your focus for tables this week are ‘FRACTIONS’. Over the last few weeks, you should have been practising finding fractions of amounts within your tables. All we need you to do with your fractions at the minute is finding simple fractions of amounts by dividing.
So, it’s really just practising your dividing tables again.
1/5 of numbers means to divide by 5, so… 1/5 of 25 = 25 divided by 5 = 5 etc.
1/3 of number is dividing by 3, so… 1/3 of 24 = 24 divided by 3 = 8
Why don't you practise these tables here (Please only choose numbers with a 1 on the top (Numerator))
We want you to spend some time adding fractions which have the same bottom number (denominator) and thinking about adding halves, quarters etc.
When adding fractions, you ONLY add the top number and the bottom number remains the same. Try to think about it like a ‘label’ in your calculation.
E.g. ¼ (one quarter) + ¼ (one quarter) = 2/4 (2 quarters) and NOT 2/8!!!!

Making 1 whole thing or subtracting from 1 whole
We would also like you to think about making 1 whole thing and taking fractions away from 1 whole thing. It may be useful to use a fraction wall to help you do this. There is a picture of one below and a link to an interactive one.
So, if I had 6/11 and I wanted to make 1 whole thing. How many more ‘elevenths’ would I need?
Well, how many ‘elevenths’ make one whole thing…that would be 11. If I already have 6 of them, then I need another 5 and the answer would be 5/11 (5 elevenths).
If I was trying to subtract from 1 then you need to think about your bottom number again – it’s called the denominator which basically means it’s the boss!
1 – 5/7 = ? If I started with 1 whole thing and wanted to take away 5/7 (5 sevenths). Well how many sevenths would make a whole thing? That would be 7. If I take 5 of them away then I am left with 2 and my answer is 2/7 (2 sevenths).

We know these tables can be tricky so please use the links to the fractions walls and games to help you practise these this week!
