What are we learning? The State of Georgia Says… M3N4 a & b Students will be able to understand the relationship between division and multiplication and between division and subtraction and will recognize that division may be two situations: the first is determining how many equal parts of a given size or amount may be taken away from the who as in repeated subtraction, and the second is determining the size of the parts when the whole is separated into a given number of equal parts as in a sharing model.

PowerPoint Presentation:

In Kid Terms I know what division means and can show it using multiplication, subtraction, and groups.

PowerPoint Presentation:

Division Means 1. Inverse Multiplication - division is the opposite multiplication. Knowing fact families can help you divide. EX: 5x6=30, 30 5=6 3 3. Sharing Groups - division means to share equally in groups. EX: 15 5=3 15 shared into 5 groups = 3 in each group. 2. Repeated Subtraction - division is just repeated subtraction of the same number until you get to zero. Ex: 6 2= means 6-2=4-2=2-2=0

PowerPoint Presentation:

Fact Family Rules S X S = B B S = S

PowerPoint Presentation:

Fact Families 24 3 8 Can you write the four math sentences that go with this fact family? S X S=B 8 X 3=24 3 X 8=24 B S=S 24 3=8 24 8=3

PowerPoint Presentation:

Fact Families 45 5 9 Can you write the four math sentences that go with this fact family? S X S=B 9 X 5=45 5 X 9=45 B S=S 45 9=5 45 5=9

PowerPoint Presentation:

Fact Families 18 6 3 Can you write the four math sentences that go with this fact family? S X S=B 6 X 3=18 3 X 6=18 B S=S 18 3=6 18 6=3

PowerPoint Presentation:

Fact Families 27 ? 3 Can you find the missing number in this fact family? What is missing: a small # or a big #? Think … ? x 3 =27. Remember the meaning of multiplication. ? x 3 =27 How many times can I count by 3 to get to 27? ? x 3 =27 How many times can I add 3 to get to 27? 9 OR

PowerPoint Presentation:

Fact Families 36 ? Can you find the missing number in this fact family? What is missing: a small # or a big #? Think … ? X 9 =36. Remember the meaning of multiplication. ? x 9 =36 How many times can I count by 9 to get to 36? ? x 9 =36 How many times can I add 9 to get to 36? 9 OR 4

PowerPoint Presentation:

Fact Families ? 6 8 Can you find the missing number in this fact family? What is missing: a small # or a big #? Think … 6 X 8 = ?. Remember the meaning of multiplication. 6 X 8 = ? 6 times I count by 8 is what number? 6 X 8 =? 6 times I add 8 is what number? OR 48

Division in Groups:

Division in Groups

Division in Groups:

Division in Groups 21 3 = Think 21 divided or shared out into 3 groups. How many groups should you draw? Now “share out” the big number. How many ended up in each group? 7

Division in Groups:

Division in Groups 18 3 = Think 18 divided or shared out into 3 groups. How many groups should you draw? Now “share out” the big number. How many ended up in each group? 6

Division in Groups:

Division in Groups 28 4 = Think 28 divided or shared out into 4 groups. How many groups should you draw? Now “share out” the big number. How many ended up in each group? 7

Division in Groups:

Division in Groups 16 4 = Think 16 divided or shared out into 4 groups. How many groups should you draw? Now “share out” the big number. How many ended up in each group? 4

PowerPoint Presentation:

Repeated Subtraction 15 3 = How many times did you subtract? Think “How many 3’s can I take away from 15?” 15 - 3 12 12 - 3 9 9 - 3 6 6 - 3 3 3 - 3 0 5

PowerPoint Presentation:

Repeated Subtraction 32 8 = How many times did you subtract? Think “How many 8’s can I take away from 32?” 32 - 8 24 24 - 8 16 16 - 8 8 8 - 8 0 4 2 12 1 14

PowerPoint Presentation:
