Show a strategy for solving a multiplication problem with 5 as a factor.
For example, 5 x 23.
(It does not have to be this one specifically.)
You could multiply by 10 and then divide that by 2.
10 x 23 = 230
Half of 230 is 115 so 5 x 23 = 115
You can multiply in parts:
5 x 10 = 50
5 x 10 = 50
5 x 3 = 15
50 + 50 + 15 = 115
What is another strategy?
W is 1/5 of X.
X is 1/3 of Z.
Z is 150.
What is W?
W = 10

If I wanted to buy an apple for every person in third grade at Carl Cozier Elementary, and each apple costs about 75 cents, about how much would I spend on the apples?
about $45
Including teachers, there are about 20 students in each third grade section. There are 3 sections, so that's about 60 people. Each apple costs about 75 cents, so I would multiply 60 by .75 to get $45 or multiply 60 by 75 and then divide by 10.
