Give students a target number such as 12.
Say:
Write down things you know about 12. Be creative. (You should get
things like a dozen, hours on a clock, number of inches in a foot, bigger than
11, a doubles fact, 4 + 8, 3 x 4, etc. It may take some hints, but usually they
will come through with great answers.) Did anyone write any
multiplication facts? (You should get 4 x 3, 1 x 12, 2 x 6, 6 x 2, and 12 x
1.) Did anyone write any addition facts that equal 12? (0 + 12, 1 + 11,
etc.) Did anyone write any subtraction facts that equal 12? (Subtraction
facts are harder, but you can try them. You are looking for something that
equals 12, such as 14 – 2 or 20 – 8.) Did anyone write any division facts
that equal 12? (Division would be facts 12 ÷ 1, 24 ÷ 2, etc.)
If students need more practice on the 4 operations, you can use Student
Sheets 19 and 20.

Give Student Sheet 19. You need to have them talk about their answers.

10) 10 – 5 = 5; 6 – 4 = 2
11) 2 x 5 = 10; 1 x 8 = 8
