5. Zero’s Pattern 0 times any number is 0
0 x 2 = 0
0 x 3 = 0
0 x 8 = 0
0 x 1 = 0
0 x 0 = 0
0 x 4 = 0

6. What is
0 x 9 =

7. One’s Pattern 1 times any number is equal to the number
1 x 5 = 5
1 x 7 = 7
1 x 6 = 6
1 x 1 = 1
1 x 8 = 8
1 x 9 = 9

8. What is

5 x 3 =
5 x 7 =
5 x 5 =
5 x 1 =
5 x 9 = . 3 5 2 . 5 . 5 4 . 5

9 x 3 = 2
9 x 7 = 6
9 x 8 = 7
9 x 1 = 0
9 x 2 = 1
9 x 6 = 5

23. Nine’s Pattern Step 2 Add a 2nd number that totals nine with the 1st number+ 7 9
9 x 3 = 2
9 x 7 = 6
9 x 8 = 7
9 x 1 = 0
9 x 2 = 1
9 x 6 = 5 =
9 x 3 = 27
9 x 7 = 63
9 x 8 = 72
9 x 1 = 9
9 x 2 = 18
9 x 6 = 54 + 3 9 = 2 9 + = 9 9 + = 8 9 + = 4 + 9 =

24. What is
9 x 7 = 6 3

25. What is
9 x 8 = 7 2

32. Ten’s Pattern Add a zero to the number that you are multiplying by ten20
10 x 2 =
10 x 4 =
10 x 6 =
10 x 8 = 40 60 80

33. What is
10 x 6 = 6

35. Real Life Applications
Congratulations!!!

36. You have been selected to build a Garden!

37. The town council of Stone Mountain decides to beautify the town.
They build square flower beds of different sizes and surround them with square tiles.
Take a look.

38. 1 by 1 bed
2 by 2 bed
3 by 3 bed

39. What is the area of the 1 by 1 bed excluding the tiles?
What is the area of the 1 by 1 bed including the tiles?
3 x 3 = 9

40. 2 x 2 = 4 4 x 4 = 16 Similarly, work out:
….the area of the 2 by 2 bed excluding the tiles.
2 x 2 = 4
…the area of the 2 by 2 bed including the tiles.
4 x 4 = 16

41. 3 x 3 = 9 5 x 5 = 25 Now, the 3 by 3 flower bed….
… area excluding the tiles… ?
3 x 3 = 9
… area including the tiles… ?
5 x 5 = 25

42. Represent your answers by using a bar graph.

43. Represent your answers by using a pie chart.
