Techniques and Formulas

Find the perimeter of a given shape.

Supporting targets:
1:

Understand that perimeter can be found by adding the lengths of the sides of a figure.

2:

See a link between finding the perimeter of rectangles and multiplication.

3:

Understand that figures with the same perimeter can look different.

3rd

Vocabulary:

Perimeter, Length, Width, Array (rectangular arrangement)

Activities:

  • Students used an array board and cubes to create different sized rectangles. Students found the perimeter of each rectangle, and recorded their strategy. (Ex. 12 + 12 = 24)
  • We attempted to connect finding the perimeter and multiplication as students explained their strategy. [Ex. 7 + 5, 2 times is 24 OR (7 + 5) x2] [Ex. 10 + 4 = 14 is (5 + 5) + (2 + 2) OR (2 x 5) + (2 x 2)]
  • Students found the perimeter of several rectangles in their workbook. Then students identified rectangles with the same perimeter and circled them by color. We noticed that the rectangles look different, but have the same perimeter.

Grade:

4th

Vocabulary:

Multiples, Product, Sum, Difference, Quotient

Activities:

  • The term "multiples" was introduced. Multiples are the numbers you land on when you skip count. A multiple is the product of one number multiplied by another number.
  • We also learned about the terms sum (answer for addition), difference (answer for subtraction), product (answer for multiplication), and quotient (answer for division).
  • Students found the multiples of 2 - 10 on hundreds charts. Students looked for patterns in multiples when skip counting or "adding on" on the hundreds charts. (Ex. 3, 6, 9, 12, add 3 more, etc. The pattern is odd, even, odd, even or diagonal.)
