1 MEAP Review: MULTI-DIGIT MULTIPLICATION And Division

2 MULTI-DIGIT MULTIPLICATION

3 5 2 5 3 2 1 Erase your "carried" numbers so you dont get confused! 373 First, we must put a place holder under the ones. Erase your "carried" numbers so you dont get confused. Multiply and "CARRY" - Just like addition! Start with the ones. Do a 'SPRAY'. Now do the tens- Use a 'SPRAY'! We must put place holders under the ones and tens. x 875 Now let's do the hundreds using a "spray". 1 1 18 6 5 + 1 Now add! 26 1 1 29 8 4 3 2 6 3 7 5

4 1 4 1 3 1 Erase your "carried" numbers so you dont get confused! 554 First, we must put a place holder under the ones. Erase your "carried" numbers so you dont get confused. Multiply and "CARRY" - Just like addition! Start with the ones. Do a 'SPRAY'. Now do the tens- Use a 'SPRAY'! We must put place holders under the ones and tens. x 328 Now let's do the hundreds using a "spray". 1 1 44 3 2 + Now add! 11 8 16 6 2 1 8 1 7 1 2

5 1 4 3 1 1 1 Erase your "carried" numbers so you dont get confused! 369 First, we must put a place holder under the ones. Erase your "carried" numbers so you dont get confused. Multiply and "CARRY" - Just like addition! Start with the ones. Do a 'SPRAY'. Now do the tens- Use a 'SPRAY'! We must put place holders under the ones and tens. x 225 Now let's do the hundreds using a "spray". 2 1 18 4 5 + 1 Now add! 7 3 8 7 3 8 8 3 2 5

6 Now take 5 minutes to do these problems: 62x48= 643x25= 246x 174= 438x 347= 752x100= .

7 ANSWERS 62x48= 2976 643x25=16,075 246x 174=42,804 438x 347=151,986 752x100=75,200 .

8 MULTI-DIGIT Division

9 Dividing Difficult Large Numbers
31) 1719 31 will not go into 1 31 will not go into 17 31 will go into 171

10 Dividing Difficult Large Numbers
31) 1719 To figure what your first number will be cover the 1 in 31 & the 1 in 171.

11 Dividing Difficult Large Numbers
31) 1719 Now ask how many 3’s will go into 17.

12 Dividing Difficult Large Numbers
5 31) 1719 Be sure to put that number directly above the 1 not the 7.

13 Dividing Difficult Large Numbers
5 31) 1719 Now multiply the 5 x 31 and place it under the 171.

14 Dividing Difficult Large Numbers
5 31) 1719 155 31 x5 16 9 155

15 Dividing Difficult Large Numbers
5 31) 1719 155 16 9 Now cover up the 1 in 31 & the 9 in 169

16 Dividing Difficult Large Numbers
5 31) 1719 155 16 9 Ask how many 3’s will go into 16.

17 Dividing Difficult Large Numbers
5 5 31) 1719 155 16 9 Place that number next to the 5 in your quotient.

18 Dividing Difficult Large Numbers
5 5 31) 1719 155 16 9 Now multiply 31 x 5.

19 Dividing Difficult Large Numbers
5 5 31) 1719 155 16 9 Subtract & your answer is 55 R14 155 14

20 Dividing Difficult Large Numbers
5 5 31) 1719 155 31 X 5 169 9 155 155

21 Check It Using the Inverse of Division:
Multiply the divisor by the quotient. X 55 155 +1550 1705 Add Remainder to the product Your answer should math the original dividend
