Fold-Up Fish With Knex

Introduction: Fold-Up Fish With Knex

This Knex Tutorial was created by two grade 2 students from Ottawa, Ontario.

They worked together to invent an object they wished to make, they developed a plan, they built the fold-up fish and then wrote their own instructions!

Fantastic teamwork!
