I'm going to ask you three quick times-tables questions from tables you already know well. Hands up when you have the answer. What is 2 × 5? What is 5 × 5? What is 10 × 4?

The interactive freezes three tables-race cards so we can look at them together. Watch how a fact you already know fast can carry you to a harder one. Have your quick facts ready.

Now we practise together on the board, with no timer. Pupils take turns to answer a short run of facts while everyone else checks each answer aloud. We go in order of difficulty: the easy 2s and 10s first, then the 5s, and last the trickier 3s and 4s, where the helper-fact trick helps most.

Now we race the timer. Pupils take turns at the board and the class calls whether each answer is right before we move on. We build up through the decks: first the 2s and 10s, then the 5s, then the 3s and 4s, and finally a mixed-tables deck where you never know which table is coming next.
