T-total Aims: To Investigate numbers in a letter T drawn on a grid ranging from 6 by 6to 9 by 9. Investigation: I will be trying to find formulae for the t-total investigation. I will be drawing a grid. Tasks: 1) Investigate the relationship between the T-total and the T-number 2) Use the 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. Key: Red = 1st Formulae, Green= 2nd Formula , Purple= 3rd formula and yellow means that numbers is used in both of the other formula's 1) Solution: 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 Look at the T-shape I Have drawn on the 9 by 9 number grid. The total of the numbers inside the T-shape is 1+2+3+11+20=37 This is called the...
