An extension of *Investigating totals*

Put the shapes on the grid but this time each row, column and diagonal has to have the same total.

You might want to make the task simpler:

- Make each
**row**total 6 - Make each
**column**total 6 - Make the
**rows and columns**total 6 - Include the
**diagonals.**

*Which shapes are you using in each row / column? Why?*

*Is there more than one way of completing the grid?*

*Look at your partner’s grid. What is the same and what is different?*

Make the task more challenging:

- Use digit cards instead of the shapes.
- Don’t give the total – Can you put the
*Numicon*shapes on the grid so that each row, column and diagonal add to the same total?

*What do you think the total might be? Why?*

*How are you going to start? What are you going to try first?*

**What if.**……..you used three different consecutive shapes?

3 twos, 3 threes and 3 fours 3 threes, 3 fours and 3 fives

or

What will the totals of each row be now?
