Let’s have two teasers on the go.
- What is the only number in which you can add up all it’s digits, and then multiply that number by three and get your original number?
Answer below, reason for your answer, and good luck once again!
In the past few lessons 1c1 have been learning how to solve linear equations by balancing. To help us visualise this we have been using a website which allows us to “balance” equations.
If you want to practice. The website is here, remember to show your working!!
1c1 have been studying tiling, tesselation and symmetry. Here are some of the things we have been looking at and tasks we have been doing.
M.C Escher - Fantastic artwork with a very strong mathematical interest. Particularlly using tesselation and symmetry.

Pentominoes - Like a dominoe but made from five squares rather than just two. How many can be made? What are their symmetrical properties and can we make tessellation patterns using them.
We have been trying to tile using the pentominoes into a fixed shape. This has developed into a challenge between the boys and girls. Who will win in the pentominoe challenge - boys or girls! The result is currently 2 - 0 to the boys.
The girls seem very motivated to launch a comeback and I am sure that next time they will be well prepared!!!

1c1 have been finding out about and discussing Prime Numbers.
Continuing from the discussions we have been having about the “100 lockers” problem. Can you tell me if 1 is a prime number? (and how you have found your answer.)
Mr. Stewart
Now that the exam results are through, the SQA have released their official marking instructions for all the maths exams set in 2008. All levels can be viewed/downloaded here. The Grade Boundaries for all subjects at all levels is also available here.
The poll in the sidebar has been updated to ask ‘what grade did you get?’, which should make an interesting comparison to the poll asked before the results were sent asking ‘what grade do you think you’ll get?’ (which can be seen below)
