Division Sentence Using Multiplication to Divide How Many Groups? 1. 2. 3. How Many in Each Group? 12 4 = 8 8 4 = 4 4 4 = 0 Using a Number Line Count back to divide Start at 12 Count back in 3s 0 5 1 2 3 4 6 7 8 9 10 11 12 13 14 16 17 18 19 15 20 4 3 2 1 Bob, Sue and Mike picked 12 apples to share equally. How many will each get? We use repeated subtraction to find out how many groups of 4 are in 12. We subtracted 4 three times. Therefore, there are 3 groups of 4 in 12. 3 equal groups 4 in each group 12 ÷ 3 = 4 number of apples number of apples in each basket number of baskets dividend divisor quotient We use division to find the number in each group. 1 2 3 4 5 6 7 8 9 10 11 12 factor factor product dividend divisor quotient number of equal groups number in each group group size total number total number number of groups 12 ÷ 3 = 4 Bob Sue Mike 3 x 4 = 12 3 x 4 = 12 12 ÷ 3 = 4 12 ÷ 3 = 4 © Copyright NewPath Learning.
