Understand the relationship that exists between area and perimeter.
Understand that figures with the same area can have different perimeters (and vice versa).
Identify patterns and strategies involved in working with area and perimeter.
Area, Perimeter, Length, Width
- Students created a layered tree by recognizing the patterns and strategies of area and perimeter
- Students were either given the perimeter or area of each layer and the length or width of one side of each layer. They used this information to find all measurements to draw each layer.
The rectangle has a length of 10 in. and an area of 30 in. sq. What is the perimeter?
If perimeter is the measurement of the outside of an object then what information do you need to find the perimeter?
What is the formula for finding the area?
If the length is 10 in. then what multiplied by 10 equals 30?
Perimeter: 26 in.
Solve multi-step word problems within 1,000,000 (addition, subtraction, multiplication, and division).
Identify the correct arithmetic processes based on the information presented in word problems.
Find the key words in word problems that indicate the correct arithmetic process to use: Addition: add, altogether, both, combined, in all, plus, sum, total; Subtraction: difference, fewer, how many/much more, left, less, minus, remains; Multiplication: times, product, each, twice; and Division: how many in each, divided by, quotient, goes into, split evenly.
Find and use the needed information in a word problem to solve.
Add, Subtract, Difference, Sum, Factor, Product, Quotient, Dividend, Divisor
Students practiced solving multi-step word problems by understanding what the problem is asking and what information they need to use to solve the problem.
