Key skills- 24-11-17

Maths

We have been learning about divisibility rules this week and applying these to help us find factors. Here is the link to a sway that will help you revise the difference between factors and multiples. It will also help you learn about the LCM- I will let you find out what that is.

After revising this information, there is an investigation to help you practice finding all factors of a number and also help with some straight forward addition. At least half an hour on these two tasks please.

 

Abundant Numbers

 

To find the factors of a number, you have to find all the pairs of numbers that multiply together to give that number.

The factors of 48 are:

1 and 48

2 and 24

3 and 16

4 and 12

6 and 8

If we leave out the number we started with, 48, and add all the other factors, we get 76:

1+2+3+4+6+8+12+16+24=76

So …. 48 is called an abundant number because it is less than the sum of its factors (without itself). (48 is less than 76.)

See if you can find some more abundant numbers!

 

Do not forget to practise your times tables facts- if you are not regularly getting over 140 in your torture tables you have some work to do! 😉

 

Literacy

remember to practice some spellings from your year 5 and 6 words list.  One on day one, revise that word and learn another on day two, revise those two and add another new one on day three and so on.

Also revise the pages on punctuation in your revision book.
