George and Freddie with their solutions to week 7's problem!


Well that's it for this year. Thank you to all of you who've had a go at these and a big thank you to the adults who have helped as needed.
I hope that you all have as nice a summer as possible in these unusual times. 😁
Remember, those times tables won't just suddenly appear in your brain  they need practise!
I hope to see you in September and all the best to Year 6!

Week 11 3rd July 2020😊
Well done to everyone who has had a go at this week's problems. Some of the answers are shown above.
The White Rose solutions are shown here  click me.😁
As for the challenger...well that did cause some serious thinking!
Ella's (Y4) dad's friend had a go and his solution is shown below. Well done!
Initially W = 4*R (80% > 20% so you would need to times R by 4 to = W)
W+76 = 3(R+48) (75% > 25% so you would now need to times R+48 by 3 to = W+76.
W+76 = 3*R+144
W = 3*R+68 (144  76)
W3*R = 68
4*R3*R = 68 (we know from line 1 that W=4*R)
R = 68
W = 272 (again W = 4*R)
Total = 340 (272+68)
Mr C's solution is shown by clicking me here...😁
This is the last set of problems before the end of term, so I hope that lots of you give some (or all!) of them a try.
Anyway, I like bar models, so I've gone back to them courtesy of White Rose...

Years 5 and 6 click me 😎
Challenger  click me!😝 I've looked at this and it hurt my brain, so it really is a toughie to finish with! If you're not yet sure about percentages, consider 80% to be the same as 8/10 (or 4/5) and 75% as 3/4 in fractional terms as it might help.

Week 5 challenge (22/05/20)
Here are the solutions to week 5 😁
Spaceship
3 Tripods (9 legs) and 7 Bipods (14 legs), or 5 Tripods (15 legs) and 4 Bipods (8 legs).
Zids and Zods
There are 3 Zids with 4 spots and 4 Zods with 9 spots.
If Zids have 5 spots and Zods have 7 spots, the possible ways of making 140 are: 28 Zids; 21 Zids and 5 Zods; 14 Zids and 10 Zods; 7 Zids and 15 Zods; 20 zods.
This week's challenge is taken from "Mathematical Challenges for Able Pupils", a Department for Education and Employment document set of challenges first produced in the year that Mr C started teaching! (Twenty years ago in 2000  but don't shout it out too loudly!).
I really like these and hope that you do too. Send in your work as usual to my page's email address given above.
Year 4 could try the one for 5 and 6 if you're feeling confident!

Week 4 (Friday 15th May 2020)
Here is the solution to this challenge. A = 2, B = 9, C = 3, D = 12, E = 8, F = 5, G = 11, H = 6 , I = 10 , J = 1, K = 7, L = 4
Well done to everyone who sent their work in to me and for letting me know how you got on. Some examples are shown above. 😋
😁 Click here for a more detailed solution to this week's challenge, together with some examples of how children elsewhere in the country (or world in some cases!) went about solving it.😀
Something rather different this week  a rather nice task using a mixed up clock face.
This challenge requires you taking a trip to the rather impressive NRICH Maths site. Click me to go there!😎
If you struggle to get going, clues 6 and then 8 are good first questions to get you started.
Have fun! Mr C.

The challenger this week is one that a few of you will have seen before, but most will not. It is one that I made up from a question that I saw on the BBC 2 T.V. quiz show "Only Connect". There are 3 parts to it, with each part getting more difficult, so most of you should be able to have a go at least at part 1. 🤓
