Old MacDonald’s Farm Katy Moser
Content Area: Mathematics • Grade Level: 4th grade • Summary: The purpose of this instructional PowerPoint is to review perimeter by building fences for Old MacDonald’s farm animals. • Learning Objective: Given the instructional PowerPoint the student will complete the slideshow and answer the perimeter questions with 100% accuracy. • Content Standard: CCSS.Math.Content.4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.
Perimeter of a Rectangle Review Perimeter is the distance AROUND a two-dimensional shape.
Review w = width h = height h w Perimeter Formula for Rectangle: Perimeter = 2 w + 2 h ~OR ~ w + w + h + h
Try It Together! • Find the perimeter of this rectangle. w = 6 inches h = 3 inches 3 inches 6 inches 2 (6) + 2 (3) = ___ Simplify: 12 + 6 = 18 Therefore, the perimeter of this rectangle is 18 inches
Old MacDonald needs help measuring fences for the animals on his farm! Can you help him?
Question 1 • What is the perimeter of the pig’s fence? 5 feet 8 feet A) 26 B) 40 C) 13
Correct!! Great Job 2 ( 8 ) + 2 ( 5 ) = 26
Question 2 • What is the perimeter of the horse’s fence? 10 feet A) 15 B) 50 C) 30 5 feet
CORRECT!! Great Job! 2 ( 10 ) + 2 ( 5 ) = 30
Question 3 • What is the perimeter of the cow’s fence? 18 36 45 3 feet 15 feet
CORRECT!! Great Job 2 ( 15 ) + 2 ( 3 ) = 36
Summary • Today we learned about finding the perimeter of rectangles. • We started with simple one-digit numbers then advanced onto two-digit numbers.
