There are to be 6 homes built on a new development site. They could
be semi-detached, detached or terraced houses. How many different
combinations of these can you find?
This challenge is to design different step arrangements, which must
go along a distance of 6 on the steps and must end up at 6 high.
Suppose there is a train with 24 carriages which are going to be put together to make up some new trains. Can you find all the ways that this can be done?
Many of you sent in your answer to this
problem, but very few of you told us how you did the problem.
Remember, it is important to tell us what you did to solve the
challenge so that someone else could follow it if they were stuck.
Georgie C from St George's School did send us details:
Well done, Georgie. Well explained solutions
were also sent in by Azure from Hanoi International School and Plum
from Ardingly College Junior School.
