Finding Perimeter of Shapes

The video tutorial introduces the concept of perimeter, specifically focusing on irregular shapes. It explains two methods for calculating the perimeter: by adding the lengths of each side and by counting the total length around the shape. The tutorial includes examples to illustrate these methods and provides instructions for students to practice finding perimeters using a graph book. The video emphasizes understanding the concept of perimeter as the distance around a shape.

What does the term 'perimeter' refer to?

• The area inside a shape

• The distance around a shape

• The volume of a shape

• The diagonal of a shape

How do you start finding the perimeter of a shape?

• By measuring the area

• By measuring the length of each side

• By calculating the volume

• By finding the diagonal

What is the first step in adding side lengths to find the perimeter?

• Multiply the side lengths

• Subtract the side lengths

• Divide the side lengths

• Add the side lengths

What is an alternative method to find the perimeter?

• Counting unit squares

• Using a calculator

• Finding the area

• Measuring the diagonal

What is the perimeter if you count 24 unit squares around a shape?

• 24 centimeters

• 6 centimeters

• 12 centimeters

• 48 centimeters

Which method involves counting the number of squares on each side?

• Area method

• Unit square method

• Diagonal method

• Volume method

What is the perimeter if the side lengths add up to 22?

• 33 centimeters

• 44 centimeters

• 11 centimeters

• 22 centimeters

How do you find the perimeter using both methods?

• By measuring the area and volume

• By counting squares and adding side lengths

• By subtracting side lengths and counting squares

• By finding the diagonal and area

What should students do after watching the video?

• Calculate the volume of shapes

• Find the area of shapes

• Draw figures and find their perimeter

• Measure the diagonal of shapes
