T-Totals Investigation

Introduction

If you look at the 9x9 grid with the T-shape, you can see that the

total of the numbers added together is 37 because it is1+2+3+11+21

which equals 37.

This is what we call the T-total (37)

And T-number is the number at the bottom of the T-shape which in this

case is 20

My tasks

The tasks I have been set are:

1) Investigate the relationship between the T-total and the T-number.

2) Use grid of different sizes. Translate the T-shape to different

position. Investigate relationships between the T-total, the T-numbers

and the grid size.

3) Use grids of different sizes again. Try other transformation and

combinations of transformations. Investigate relationship between the

T-total, the T-numbers, the grid size and the transformations.
