1 Early Division on MathLine on MathLine

2 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… Starting with a single Digit Divisor Early Division

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

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

7 Equal Groups Division Early Division

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 of 18 through Trial & Error 18 ÷ 3 Early Division

10 Groups of 7? 4 77 No 18 ÷ 3 Early Division

11 Groups of 6? 666 Yes 18 ÷ 3 Early Division

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

13 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

14 Division as repeated subtraction ÷ 6 = Early Division

15 One group of 6 from 24 One group of 6 from ÷ 6 = Early Division

16 Two groups of 6 from ÷ 6 = Early Division

17 Three groups of 6 from ÷ 6 = Early Division

18 6666 Four groups of 6 from ÷ 6 = 4 Early Division

19 4321 Quotient is 4, or there will be 4 teams to play soccer. 24 ÷ 6 = 4 Early Division

20 22 ÷ 4 = 22 ÷ 4 = Early Division

21 4 and divide 4 22 ÷ 4 = 22 ÷ 4 = Early Division

22 44 22 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

23 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

24 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

25 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

26 5 groups of ÷ 4 = 5 22 ÷ 4 = 5 Early Division

27 54321 With two left over, remainder of 2 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2 Early Division

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

29 Which is 2/4 or 1/ ÷ 4 = 5 r 1/2 22 ÷ 4 = 5 r 1/2 Early Division
