  1. Understanding Multiplication and Division Year 2 Summer Term Week 10 Lesson 1

  2. Today we will be learning to: • multiply and divide numbers • use multiplication and division vocabulary • multiply and divide by 10 • find unknown numbers.

  3. Mental Activity What’s my number operation?

  4. One child wears a headband with a number attached to it. That same person calls out a number to the class.

  5. The class multiplies that number by the number on the headband and calls out the answer. The child with the headband works out what the number on the headband is.

  6. Main Activity Today we are going to work on problems involving multiplication and division including finding unknowns.

  7. Function machine. This machine carries out number operations.

  8. Function machine. This is a x1 function machine. x1

  9. Function machine. 4 x1 If 4 goes in what number will come out?

  10. Function machine. 5 x1 If 5 goes in what number will come out?

  11. Function machine. x1 10 If 10 goes in what number will come out?

  12. Function machine. 8 x1 If 8 comes out what number went in?

  13. Function machine. This is a x2 function machine. x2

  14. Function machine. 4 x2 If 4 goes in what number will come out?

  15. Function machine. 12 x2 If 12 goes in what number will come out?

  16. Function machine. 8 x2 If 8 comes out what number went in?

  17. Function machine. This is a ÷2 function machine. ÷2

  18. Function machine. ÷2 6 If 6 goes in what number will come out?

  19. Function machine. 10 ÷2 If 10 goes in what number will come out?

  20. Function machine. ÷2 7 If 7 comes out what number went in?

  21. Practise using multiplication and division function machines for two-step functions such as x2 x10. Use a cardboard box to make a function machine for x1 or x2. Use different colours of wool for each in/out pair of numbers. Practise using multiplication and division function machines for x10, x3 and ÷10. Group Work
