Year 4 Investigate if all 3d Cube Nets make a Cube

In our Year 4 Maths group we discovered that you can make many different net arrangements with six 2d squares, but are they all nets that all fold into a 3d cube?  We decided to investigate this further.  We used square tiles and masking tape to create each net and then tried to fold them up.  We started to find that we were getting better at visualizing the net being folded up and could make pretty accurate predictions about which nets would or wouldn’t make a cube before we tested them.  If you would like to have a go, try our worksheet and test the nets yourself.  We also investigated dice nets.  You can have a go at arranging the numbers on the dice net that we found most challenging here.
