What does the cube look like?


I created this worksheet based on a problem on the excellent NRich Maths website.

The pupils have to use their skills of visualising 3D shapes to draw patterns on the faces of a cube net after deciphering where they should go by looking at 3D views of the cube. To scaffold the task an actual cube net is also included so they can build what they think is the right solution. There is a nice extension for the future engineers who have excellent visualisation skills.

I found this to work well with medium-to-high attaining year 7 and 8 classes.

Making 100


Pupils write out the digits 1 to 10 like this:

1   2   3   4   5   6   7   8   9   10

The aim is to create an expression that equals 100 by putting as many + – X and / signs between the digits as they like. You might like to demo one like this:

1    2   3 + 4   5   6  X 7 / 8 – 9 = 123 + 456 X 7 / 8 – 9 = 513

Obviously this one is too high but it does illustrate the method. You can decide whether the pupils must use BODMAS or not (I’d suggest they do!) and whether they are allowed to put brackets in as well.

There are many solutions and you might like to post them in the comments section below when you find them!

Thanks to Cat for this engaging little starter. It might make a brilliant homework too!

Have fun!

Sudoku Fridays


Start your Friday lessons with a Sudoku challenge for your students! Use it as a starter over a series of weeks and see their progression. Get them to discuss their logical thinking and to explain how they solve the problems. Can they write a set of rules you can use to solve all Sudoku puzzles?
