**Michele Papageorghiou**Which of the following tables is the 1,3,6 and 9 times tables?

- In this investigation, children should match each of the tables below to the 1, 3, 6 or 9 times tables.
- The values of each letter are unique to each table, i.e. C in table W does not have the same value as C in table X]

TABLE W | TABLE X | ||

H X A = A H X F = F H X G = G H X C = C H X H = H H X J = J H X D = D H X I = I H X B = B | A = B = C = D = F = G = H = I = J = | D X F = BG D X A = D D X D = JA D X C = IH D X I = AJ D X H = FC D X J = HI D X G = CF D X B = GB | A = B = C = D = F = G = H = I = J = |

TABLE Y | TABLE Z | ||

C X G = BG C X J = AF C X H = JD C X I = DG C X B = C C X C = AC C X E = DE C X A = BE C X D = GD | A = B = C = D = E = F = G = H = I = J = | H X J = GJ H X F = BI H X B = D H X I = BG H X H = F H X G = H H X D = GA H X C = GB H X A =BC | A = B = C = D = F = G = H = I = J = |

The information above can also be found on a worksheet below.
