This is speeded up but I will bet you can do it in about a minute any time you need to have the multiplication tables for the Threes or the Sevens. Reverse direction, Put 1-2-3-4-5-6-7-8-9-0 in starting bottom left going up for the Threes and down right for the Sevens.
Then for the Threes in front put 0s in the first row (optional, but it makes the pattern clearer), 1s in the second row, 2s in the second row, and then 3 in front of the 0.
For the Sevens, put in front 0-1-2 (first row) 2-3-4 (second row) and 4-5-6 (third row) and 7 in front of the 0. The pattern is Same-UP-UP in all three rows.
