Title – Multiplication Game
By – Tania Yap
Primary Subject – Math
Grade Level – 3 – 4
Duration – 45 minutes
- Pupils should know the times table.
- Pupils should be able to recall their times table and make complete number sentences (simple and complex)
- Multiplication strips (question strips & number strips)
- Tokens e.g. ice cream sticks/coloured chips
- 1. Pupils recite the times table.
- 2. Elicit multiplication number sentences that give the answer 12 from pupils. E.g. 2 x 6, 6 x 2, 3 x 4, 4 x 3
- 3. Demonstrate a complex number sentence involving + or – (5 x 2 + 2, 3 x 5 – 3).
- 4. Explain to pupils that though the sentences involve other operations, they still arrive at 12 as the answer.
- 5. Explain that number sentences are solved from left to right with multiplication phrases being solved before addition phrases.
- 6. Demonstrate a complex number sentence involving + or – phrase before a x phrase (6 + 2 x 3, 4 + 4 x 2).
- 7. Explain to pupils that though the sentences involve other operations, they still arrive at 12 as the answer, because we solve the multiplication part first, then the addition. (2 x 3 = 6, 6 + 6 = 12; 4 x 2 = 8, 4 + 8 = 12)
- 8. Introduce the multiplication strips to the pupils.
- 9. Get three pupils to demonstrate the previous examples by holding up the strips. E.g. demonstrate 5 x 2 + 2 by holding up the question strip “5 x 2″, number strip “2″ and “12″. Verbally read the number sentence 5 x 2 + 2 = 12.
- 10. 1/3 of the pupils to take a question strip each.
- 11. 2/3 of the pupils to take a number strip each.
- 12. Pupils will start to search for corresponding strips to make number sentences.
- 13. When they have made a complete number sentence, the pupils will come to the teacher to verify the sentence.
- 14. The teacher will check and write the sentences on the board. The teacher will then issue a token to these pupils.
- 15. After that, these pupils will exchange their existing strips for new strips from the pool of spare strips and start making new number sentences.
- 16. Note that pupils are not allowed to call out their targets but to hold up their strips and go around looking for the strips that could make a complete number sentence.
- 17. At the end of the activity, the pupil with the most number of tokens will get a reward.
- 18. Pupils will complete a worksheet as homework.
