This outer space-themed video teaches the concepts of area and perimeter. Students learn how to calculate the area of rectangles by counting unit squares and the perimeter by adding side lengths, and then by using the formulas length x width and (2 x length) + (2 x width). The song walks students through a real-life example of finding area and perimeter. Activity 1. Listen to this song for a further understanding of area and perimeter. 2, take a piece of paper and draw 4 rectangles for me that all have a perimeter of 8cm 3. label the 4 rectangles with the numbers for length and width 4. calculate the area of each rectangle and label this area next to each rectangle 5. Write me 2 or more sentences on why the perimeter is the same for every rectangle but the area's are different.
