Y2 Maths Challenge: The Abacus
Hello!
This week I’ve asked you to complete more times tables activities on MyMaths. You need to know your 5s, which can be a little trickier than the 10s or the 2s. If you’re finding it tricky, have a go at this worksheet first and ask for help from a parent, sibling or carer. You don’t have to do this sheet, only do it if you’re finding the MyMaths task hard!
finding the 5s
Remember the five times table is also really handy for telling the time! We can use it to help us figure out the minute scale.

A maths investigation! Email your answers to westgreen.yellowclass@gmail.com
Follow the rules on the sheet carefully. There are two pages of questions (so click the down arrow at the bottom of the sheet to find page two). Page three tells you the answers, no peeking until you’ve finished investigating! What patterns will you find?

I’m impressed that you jumped ahead further to 128!
You might not have a strategy yet to easily work out 128 + 128, but next week there will be a video lesson and I think you’ll be able to do it then more easily.

128+128=256.
I’m sure Yi-Xuan knows this.

4. 32, 64 this was hard. My mum helped me.-
It is a good idea to ask your Mum for help. When I can’t be with you in the same room, your Mum can be the teacher! If she isn’t too busy with her own work!

Can anyone solve these ?
1. 3,9,27 ,………., ……….
2 5, ………., …………., 20, ……….., 30
3. 123,………, 115, 111, ………., 107-
Number 1 is remarkably hard. I’m not even sure Yi-Xuan will figure that one out!
I think your third one might have a mistake in it. What do you think?

1) 3,9,27,33,39
2) 5,10,15,20,25,30
3) 123,121,119,117,115,111,109,107.
