Study Notes

Multiplication Strategies

Charley's model represents 17 x 17 = 289
30 x 60 = 1800
3 x 269 = 807

Area and Perimeter

A school's 4th grade is going on a field trip with 68 students
Each student will pay $3 to attend, for a total cost of 68 x 3 = $204
Mr. Petersen's garden has a length of 10 meters and an area of 40 square meters.
The perimeter of Mr. Petersen's garden is 28 meters.
This year, Mr. Petersen wants to make his garden 3 times as long and 2 times as wide
The new garden will have an area of 240 square meters and a perimeter of 64 meters

Word Problems

The high school art teacher has 9 boxes of crayons with 52 crayons in each box, for a total of 9 x 52 = 468 crayons
The elementary school art teacher has 6 boxes of crayons with 104 crayons in each box, for a total of 6 x 104 = 624 crayons
Both teachers have a total of 468 + 624 = 1092 crayons
Grant had 35 baseball cards, Luke had twice as many, so Luke had 35 x 2 = 70 cards
Luke then bought 12 more cards for a total of 70 + 12 = 82 cards
A movie theater has two rooms, Room A with 9 rows of seats with 18 seats in each row, for a total of 9 x 18 = 162 seats
Room B has three times as many seats as Room A, so it has 162 x 3 = 486 seats
The total number of seats in the movie theater is 162 + 486 = 648 seats
Ariella purchased a rectangular rug with a length of 12 feet and a width that is 3 feet less than the length, for a width of 12 - 3 = 9 feet
The area of the rug is 12 x 9 = 108 square feet
The perimeter of the rug is 2(12 + 9) = 42 feet

Patterns

The numbers 32, 320, and 3,200 follow a pattern of multiplying the previous number by 10
The next number in the pattern is 3,200 x 10 = 32,000
