Step 1: Let's Learn

Read it, or press Listen and follow the words.

Fluent means you know it, not that you can work it out quickly.

Strategy first, recall second

Every fact you know started as a strategy. Using the strategy often is what makes it stick.

Division comes free

Every multiplication fact you learn gives you two division facts with it.

Why recall matters, not just method

When you are dividing a four-digit number in Grade 4 or comparing fractions in Grade 5, you will need dozens of table facts along the way. If each one takes ten seconds to rebuild, the real problem never gets your attention. Recall frees your thinking for the part that is actually hard.

How to get there

Short and frequent beats long and rare — five minutes a day is worth more than an hour on Saturday. Practise the facts you get wrong, not the ones you already know. And practise in both directions, so 6 × 7 and 42 ÷ 7 are equally quick.

Keep the strategies

Even when the facts are memorised, keep the strategies. They are your safety net when memory fails under pressure, and they are the foundation for multiplying larger numbers, where nothing is memorised and everything is built.

Step 2: Try It Yourself

Tap and try it out.

If a fact will not come, cut the array and build it.

8 × 7 = 56

8 × 7 = (8 × 5) + (8 × 2) = 40 + 16 = 56

The array is cut into 8 × 5 and 8 × 2. Two easier facts that add to the same total.

Step 3: Watch an Example

One step at a time.

Watch Ana Choose a Road

Ana is given 6 × 8 and does not recall it.

  1. Step 1

    She does not count in eights. That is the slow road.

Step 4: Your Turn

Practice makes it stick.

Mixed Facts

Use a strategy if a fact will not come. Never count up.

6 × 8 = ?

2 of 4

9 × 7 = ?

3 of 4

56 ÷ 8 = ?

4 of 4

81 ÷ 9 = ?

Step 5: Quick Check
