The Sieve of Erastothenes - Can you remember how to find all the Prime Numbers from 1-100?
Our Scale Drawings
With some of these exercises we had scale down the drawings from reality e.g. a basketball court or a swimming pool. We used scales like 1:100 or 1:200. Every centimetre would measure as 1/2 metres in reality.
On some of these images we had to work in reverse using a scale of 1:0.5, and so we were scaling up, making the image bigger. Examples shown are stamps and playing cards. All of this work was done on squared centimetre paper.
