Math Problems

WALT: Solve division and multiplication problems using various strategies.

There are 125 students in a school. They were given some sketching pencils by and Art Supplies Store.
  1. If each student received 8 pencils each, how many pencils were there altogether?
  2. If there were 25 pencils in a packet, how many packets of pencils did they receive?
  3. If the price of one packet of pencils was $12.00, how much did the store spend on the pencils?

Strategy
Answer
A.If each student received 8 pencils each, how many pencils were there altogether?
125 x 8 =
100 x 8 = 800
20 x 8 = 160
5 x 8 = 40
800 + 160 + 40 = 1000
1000 pencils
B.  If there were 25 pencils in a packet, how many packets of pencils did they receive?
1000 ➗25= 40
I know 25 x 4 = 100, so 1000 ➗100 = 10, so 10 x 4 = 40
40 packets
C. If the price of one packet of pencils was $12.00, how much did the store spend on the pencils?
$12.00 x 40 =
12 x 10 = 120
So 120 x 4 = 480
$480.00
