Learning Objective: I can create a 3D shape from a 2D net

Context: The wicked witch’s cottage from Hansel and Gretel

Vocabulary: Net, 2D, 3D, quadrilateral, rectangle, square, trapezium, cuboid

Teaching and Learning: Discuss vocabulary. Discuss the shapes of the net. Teacher demonstrates making the cuboid which makes the main structure of the witch’s cottage.

Activity: Making the witch’s cottage

1. Firstly, with scissors, cut around the outside of the net carefully on the lines. 2. Then, score the dotted lines gently for the tabs. 3. Next, fold the tabs and, with masking tape, check that the cuboid will attach together

effectively. 4. Unattach the masking tape so you can decorate the cottage.
