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?
