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

Students think about Early Division both ways! Early Division

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

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

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

Equal Groups Division Early Division

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

Find 3 equal groups of 18 through Trial & Error 18 ÷ 3 Early Division

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

Groups of 6? 666 Yes 18 ÷ 3 Early Division

See 18 divides by 6 - 3 times. So each pile has 6 cookies. 66 6 18 ÷ 3 = 6 Early Division

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

Division as repeated subtraction 24 24 ÷ 6 = Early Division

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

Two groups of 6 from 24 66 24 ÷ 6 = Early Division

Three groups of 6 from 24 666 24 ÷ 6 = Early Division

6666 Four groups of 6 from 24 24 ÷ 6 = 4 Early Division

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

22 ÷ 4 = 22 ÷ 4 = Early Division

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

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

444 22 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

4444 22 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

44444 22 ÷ 4 = 22 ÷ 4 = 4 and divide Early Division

5 groups of 4 54321 22 ÷ 4 = 5 22 ÷ 4 = 5 Early Division

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

Notice that remainder 2 is also 2 of 4 24 22 ÷ 4 = 5 r 2 22 ÷ 4 = 5 r 2 Early Division

Which is 2/4 or 1/2 24 22 ÷ 4 = 5 r 1/2 22 ÷ 4 = 5 r 1/2 Early Division
