GRADE FIVE- DESIGN YOUR DREAM BEDROOM WEBQUEST
Lesson Six-Calculating Area and Perimeter Quickly
Play game 1 below. Try five rectangle shapes and then five compound shapes.
Write a comment below about how you could find the area of a shape quickly without counting all the squares. Think about our previous work on rows and columns.
Remember to put your name on the comment.
Use the geoboard to make 5 different rectangles. I would like to see you write the answer with your working out in your maths book. For example write Perimeter = 2+3+2+3 Having trouble ask a classmate for help. Explain any patterns you see in your answers to calculate the perimeter of a rectangle. Write your explanation in your maths book. How could we shorten our answer and work out perimeter more quickly.
