Investigation into T-Totals The 9*9 grid below has a T - shape drawn on it. The sum of the numbers inside the T - shape is called the 'T - Total'. The number in the bottom square of the T - shape is called the 'T - number' (Number in green). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 So, the T - total for this T - shape is: 1 + 2 + 3 + 11 + 20 = 37 So 37 = T-total The T-number for this shape is 20 (shown in green). Aims: 1) Investigate the relationship between the T-total and the T-number. 2) Use grids of different sizes. Translate the T-shape to different positions. Investigate relationships between the T-total and the T-number and the grid size. 3) Use grids of different sizes again. Try other transformations and combinations of transformations. Investigate relationships between the T-total and the T-number and the grid size and the transformations. Part 1 - The Solution T69 = 50 +...
