    I rate this site as a 5!"

Here are the totals obtained by following different routes through the maze:

Solution

100 x 2 x 0.5 x 0.1 x 1.5 = 15
100 x 2 x 0.9 x 1.5 = 270
100 x 2 x 0.2 x 0.1 x 1.5 = 6
100 x 2 x 0.2 x 0.5 = 20
100 x 2 x 0.2 x 5 x 3 = 600
100 x 0.8 x 0.1 x 1.5 = 12
100 x 0.8 x 0.5 = 40
100 x 0.8 x 5 x 3 = 1200
100 x 1.3 x 1.5 x 0.1 x 1.5 = 29.25
100 x 1.3 x 1.5 x 0.5 = 97.5
100 x 1.3 x 1.5 x 5 x 3 = 2925
100 x 1.3 x 3 x 3 = 1170
100 x 1.3 x 0.3 x 1.6 x 3 = 187.2

The largest total is 2925

The smallest total is 6

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

Maths is Important!

"Mathematics equips pupils with uniquely powerful ways to describe, analyse and change the world. It can stimulate moments of pleasure and wonder for all pupils when they solve a problem for the first time, discover a more elegant solution, or notice hidden connections. ...

Mathematics is a creative discipline. The language of mathematics is international. The subject transcends cultural boundaries and its importance is universally recognised. Mathematics has developed over time as a means of solving problems and also for its own sake."
