For most students, visualising how the net folds to form a cube, is a difficult concept. These questions are a regular occurrence in 11 plus entrance exams and are also important for the CEM (Durham University) exam.
Three different types of questions can be asked:
Type 1: A net is given and the student must identify the cube that can be formed from the given net.
Type 2: A net is given and the student must identify the cube that cannot be formed from the given net.
Type 3: Three or four different views of the same cube are given and the student must identify the correct net of the cube.
In this series of videos we show you how to approach these questions.
The video tutorials can also be used as a revision aid before the 11 plus entrance exams. In each video we show you the theory needed to solve the questions and we also give two or three worked examples of typical exam questions. We also use animations to show you how the cubes are formed.
Video 1 shows you how the 11 nets can be folded to form the corresponding cubes.
Video 2 shows you how to fold nets with numbers on each face.
Video 3 shows you how to identify the correct cube if there are diagrams/shapes on the faces.
