Pebble creature problem solving & estimation

How many pebble creatures will sink the boat?!

Curriculum Outdoors

Introduction

You can do all sorts of things with a pebble creature!

A good opportunity to use some problem solving and estimation skills.


* Muddy Faces actively promotes child-led outdoor play & learning. We recognise and believe in the curiosity that children have and their drive to explore and discover. We hope that you will bear this in mind when considering more prescribed activities like this one – often much more creative ideas will occur if resources are simply provided and children are given the time and space to explore independently.
