Maths Bulletin

“Our vision is to be the school of choice for our local community, developing successful young people with high aspirations, who show respect for all and endeavour to become the very best that they can be.”

Welcome Welcome to another edition of the Maths Bulletin where we hope to share some fun Maths and celebrate the work over the last few months.

I am extremely pleased to have students back with us in school but I was amazed at how well the students adapted to remote learning.

Good luck to our Year 11 and 13 students who are currently sitting assessments. Remember that your Maths teachers are available via email just as they were while remote learning.

The last few weeks have been busy and I hope that you all get some rest over the Easter break. Please enjoy this issue and peruse the delightful mathematical puzzles and memes, try the latest chess moves just like in the Queen’s Gambit!

TT RockStars With lockdown over, a new Times Table RockStars competition will begin!

In the new competition, accuracy will be key as the winners will be determined by how many they answer correctly. The competition will be running longer and the final tally will be checked at the end of the next half term on 27th May. The results will be published in the next Maths Bulletin.

As always, the top 5 students from each year group will earn House Points. 50 points for 1st place, 40 points for 2nd, 30 points for 3rd, 20 points for 4th and 10 points for 5th.

To see if you can make it onto the leader board next half term, head over to the TT RockStars website, www.ttrockstars.com. Your login details can be found in Edulink under the documents section. Contact your class teacher if you have any problems.

Speed is important but it’s no good if you are not accurate! Good luck and let's get rockin!

Origami Challenge - Easter Special!

For this edition, I thought we could try something special for Easter. A double challenge this week with a bunny and a basket for our Easter eggs! You will need to start with square paper but you can easily make some using any rectangle shaped paper. You will need one sheet for each rabbit and two sheets for the basket. Follow the instructions below to make square paper https://www.youtube.com/watch?v=PPxi1dIWRws And below are instructions on how to make a bunny and the basket. https://www.youtube.com/watch? v=6QqBvy_yO_M https://www.youtube.com/watch? v=wyAhfsd2PL0 Miss Smith helped with making the bunnies and with the Mini Eggs in the basket! The basket was able to hold quite a bit but as always, chocolate does not last long in the Maths office…

Puzzling Puzzles and UKMT Maths Challenge Answers Cross Number

UKMT Maths Challenge Answers Junior E All four numbers may be obtained: 36 = 20 + 16; 195 = 201 – 6; 207 = 201 + 6; 320 = 20 x 16.

Intermediate D When the net is folded up to form the rhombicuboctahedron, the left-hand edge of the square marked X is joined to the right-hand edge of the square marked E so that the eight squares at the centre of the net form a band around the solid. In this band, the square opposite square P is the square which is four squares away from P, that is square D. so if the square marked P is placed face down on a table, then the square marked D will be facing up.

KenKen

Senior B As the circle rolls, the centre of the circle moves along four straight lines shown as dashed lines. Each dashed line has length 5 – (1 + 1) so the total distance travelled is 4 x 3 which is 12.
