The Snapping Crocodile

Pedagogical guidelines and construction instructions

This toy is a cardboard moving toy which makes use of the scissors mechanism. It has the face of a crocodile and functions with the principle of a lever so that a child can use to make the crocodile’s mouth open. It allows children to mechanise the concept of the animal and use it as an object of play while still gaining educational insights.    

Target group

The Crocodile example described here is designed for children from 4 to 7 years old. Teachers can adapt the proposal to other ages.

The teacher can decide depending on her/his knowledge of the children whether the children should work in groups or individually. 

Learning goals

When constructing the Crocodile several learning goals can be achieved, and in particular to learn about physics and mechanics, in particular linkages; about mathematical concepts in particular during the construction and assembly process, about the animal and its environment etc.
