Why do this problem?
provides an appealing context for practising the three times table. It gives an opportunity for children to realise that there is not necessarily just one answer to a mathematical problem.
Children might find it helpful to use this sheet
of the grid with counters.
How are you deciding where to go?
Which square could we go to next?
Do you think there are more than one route?
If so, how you you find it?
Is there a way of remembering your route?
Invent a similar activity that would mean Froggie only jumped on a square that is four more than where she is. So you choose which numbers go where.
You could suggest that children write out the numbers in the three times table first. They might also find it easier to start at $30$ and work backwards.
