Early Division Early divisionincludes Early division includes : Division as Repeated Subtraction Breaking into Equal Groups or

3
Students think about Early Division both ways! Early Division

4
Equal Groups Division Division as Repeated Subtraction Computational Division Division with Remainders Division on MathLine includes : Division on MathLine includes : Long Division (single digit divisor) Early Division

5
MathLine will effectively model ALL aspects of division for your students! Early Division

6
This lesson covers Early Division Equal Groups Division Division as Repeated Subtraction Division as Repeated Subtraction Computational Division Computational Division

7
Equal Groups Division Early Division using ‘trial & error’

8
If we have 18 cookies in a jar, and we put them into 3 equal piles. How many in each pile? Early Division

9
Find 3 equal groups Early Division

10
Find 3 equal groups of 18 using ‘trial & error’ 18 ÷ 3 Early Division

11
Groups of 7? 18 ÷ 3 Early Division 1 2 34 56 7

12
Groups of 7? 18 ÷ 3 Early Division 1 2 34 56 7

13
Groups of 7? 18 ÷ 3 Early Division 1 2 34 No

14
Groups of 7, 7 & 4 are not equal 18 ÷ 3 Early Division 774

15
Groups of 6? 18 ÷ 3 Early Division 1 2 34 56

16
Groups of 6? 18 ÷ 3 Early Division 1 2 34 56

17
18 ÷ 3 Early Division 1 2 34 56 Yes Groups of 6?

18
Early Division 18 ÷ 3 = 6 See 18 divides by 6 - 3 times. So each pile has 6 cookies. 123

19
Division as Repeated Subtraction Repeated Subtraction Early Division

20
If we have 24 students playing soccer at gym time, and they split up into teams of 6. How many teams are there to play soccer? Early Division

21
Now divide by subtracting Early Division

22
Division as repeated subtraction One group of 6 from 24 24 ÷ 6 = Early Division 123456

23
24 ÷ 6 = Early Division Two groups of 6 from 24 Two groups of 6 from 24 123456

24
24 ÷ 6 = Early Division Three groups of 6 from 24 Three groups of 6 from 24 123456

25
24 ÷ 6 = Early Division Four groups of 6 from 24 Four groups of 6 from 24 123456

26
24 ÷ 6 = 4 Early Division Answer is 4, or there will be 4 teams to play soccer. 12 34

27
Computational division Computational division Early Division Typically done through repeated subtraction Typically done through repeated subtraction

28
22 ÷ 4 = 22 ÷ 4 = Early Division

29
22 ÷ 4 = 22 ÷ 4 = Early Division 1234

30
22 ÷ 4 = 22 ÷ 4 = Early Division 1234

31
22 ÷ 4 = 22 ÷ 4 = Early Division 1234

32
22 ÷ 4 = 22 ÷ 4 = Early Division 1234

33
22 ÷ 4 = 22 ÷ 4 = Early Division 1234

34
22 ÷ 4 = 5 22 ÷ 4 = 5 Early Division 12 5 groups of 4 With how many left over?

35
Early Division 12 With two left over, remainder of 2 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2

36
Early Division 12 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2 Notice that remainder 2 is also 2 of 4 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2

37
Early Division 12 Equal to 2/4 or 1/2 22 ÷ 4 = 5 r 1/2 22 ÷ 4 = 5 r 1/2

38
Computational division Computational division Early Division also can divide also can divide from left to right

39
Early Division 1234 22 ÷ 4 = 22 ÷ 4 =

40
Early Division 1234 22 ÷ 4 = 22 ÷ 4 =

41
Early Division 1234 22 ÷ 4 = 22 ÷ 4 =

42
Early Division 1234 22 ÷ 4 = 22 ÷ 4 =

43
Early Division 1234 22 ÷ 4 = 22 ÷ 4 =

44
Early Division 1 2 345 5 groups of 4 With how many left over?

45
Early Division With two left over, remainder of 2 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2 12
