Frog Jump
A frog gets exercise by jumping around a pond. It
jumps from lily pad to lily pad in the sequence
shown. It starts at the lily pad labelled S. It ends on
the lily pad it is currently sitting on. Each black dot
marks a lily pad on which the frog has landed.
* pilot years - Castors and Kits can enter as individuals or small groups (up to 4)
The “compass” shows 8 possible directions of
a jump as integers from 0 to 7.
Which sequence describes the frog’s path?
