Look at these three numbers on the board: 15, 25, 40. Each one is an answer in the five times table. What do you notice about the digit at the very end of each of them? And what about the ten times table — what do all its answers end in?

Here are five hundred squares, each with one set of multiples shaded: fives, tens, twos, then fours. Look at where the shaded squares sit and the pattern they make.

Today we shade and read each table's pattern together, in this order: first the 2s, then the 10s, then the 5s, then the 4s. Each time, a pupil comes to the board to shade the multiples, and then the whole class says what shape the pattern makes and what the answers end in. Watch for the moment when the 4s land right on top of the 2s.

Now we shade each table as a whole class, working up through four rounds: the 2s, then the 10s, then the 5s, then the 4s. A pupil shades the multiples, we press Check to confirm the grid is right, and the class calls out one fact from that table they could work out from its pattern.
