2. Today we will be learning: how to use a known fact to work out an unknown fact how to use doubling and halving.

3. Mental Activity We are going to play Multiplication Bingo.

4. Work with a partner. Draw a grid on paper. Write down six even numbers from 2 to 30. Multiply each of the next card numbers that appear by 2. If you have the answer on your grid, cross it out. The first pair to cross off all six numbers wins.

20. Top Tip The multiples of 4 are alternate even numbers. We can practise saying them. Say the blue numbers loudly and whisper the orange numbers. 2412148616101820 22243234282636303840

21. Group Work Work with a partner to find out which numbers are multiples of 4. Practise doubling numbers. Double numbers from 0 to 30, then double them again. Record each operation as a number sentence.
