This cameo has a From The Classroom section which includes photos of the students' gallery of solutions and slideshows from two students showing how they can fold particular nets into cubes. There are a total of 11 distinct nets for the cube (Turney 1984-85, Buekenhout and Parker 1998, Malkevitch), illustrated above, the same number A triangle is drawn at each end of one of the rectangles, making sure that when folded the edge lengths match exactly. Net -- a two-dimensional shape that can be folded into a three-dimensional figure is a net of that figure.

For each net, six faces are connected by five edges Have students share and write what they learned about a cube. Place the students in pairs or groups of three and share this canvas and let them work on which one of these sets fold up to a cube. Alternatively, consider simply asking each group to find all possible arrangements of 6 cubes that can make a net. If you select this approach, you don't need to share a starting canvas with them. This task is also included in the Task Centre Kit for Aboriginal Students and the Primary Library Kit. Solutions for tasks in the latter kit can be found here, including the 11 cube nets. Hold up a cube and discuss with the students the different attributes of a cube making sure they call the "sides" faces. Ask students to write the attributes in their math journals. A cube is a symmetrical three-dimensional shape which consists of six square faces, twelve edges, and eight vertices.You could also use this as a follow-up activity after using our Properties of 3D Shapes Worksheet. Why do we use nets of shapes to help us with geometry? Show 1 x 6 rectangular arrangement of the squares. You may use different colors for the square faces to show how some of the faces coincide when folding them up. Alongside their primary use in geometry classes, you may choose to use this template in other lessons to create dice-led games, such as in Phonics, Art or English. This is a two-dimensional paper model net of a cube which can be folded and glued to build an amazing 3-D cube. It's no use having 5 or 6 squares in a line, because they will fold up with missing 'tops and bottoms'.

Whole Class Investigation Tasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works.

As a class choose a two- or three-dimensional object in the classroom (for example: the globe or the flag). Have the students come up with attributes while the teacher lists the attributes on the board.
