Bee lesson.

Our class used BeeBot robots to learn more about area and perimeter.  Each group had one student documenting on the iPad using an eBook creator through the Book Creator app.  The Lesley team helped design the lesson in conjunction with the grade three teachers to review area and perimeter.  Here’s a YouTube video to help you see the students in action: BeeBot Area and Perimeter.  The students loved the lesson and they are excited to use the BeeBot for future lessons!

Below you can see a sample of the lesson’s challenges.

Lesson: Measuring Perimeter and Area in Bee Units

Challenge 1: Measuring in Units

  1. Using a Bee Bot robot, pipe cleaners and string, show us the size of a Bee Unit?
  • Take a picture
  • Add a short explanation of how you figured it out.

 

Challenge 2: Find the Perimeter

Do you think these shapes have the same perimeter or different?

Circle one:

Same perimeter

Different perimeter

How many Bee Units is each side of your shape(s)?

Given this information, what have you learned? What is the perimeter for each shape?

Perimeter of shape 1: ________ (Bee Units)

Perimeter of shape 2: ________ (Bee Units)

Use your BeeBot to prove your work and double check your perimeter. You can write your code on a piece of scrap paper and take a picture once your code has been tested (and works).

Challenge 3: Finding the Area

Based on what you learned about perimeter, can you predict if the area of the two shapes is the same or different?

Circle one:

Same area

Different area

Let’s prove your thinking. Using your Bee Unit squares, how can you figure out the area of each shape?

How many Bee Unit squares did you use (take a picture):

    • Area of shape 1: ________ (Bee Units)
    • Area of shape 2: ________ (Bee Units)

Let’s prove your work. Use the measurements from your perimeter challenge to calculate the area of each shape? Show your work (formula)

Did you need to use different strategy to calculate the area for each shape? If so, what strategies did you use?

Thank you to the Lesley team for their support with this lesson!

Perimeter and area.

It’s been a long week of MCAS review.  The children have been taking practice tests and reviewing the concepts they learned this year.  Students were mixing up perimeter and area so we looked for fun ways to remember the difference between them.  Here are the key points we need to remember:

Perimeter–the fence around the outside, add up the sides

Area–the grass on the playground, multiply length times width OR tile in the squares

We watched some videos on Brain Pop Jr. and we watched some songs online.  These were our favorites:

Mrs. Burk’s Perimeter Rap made us laugh!  (And it helps us remember to multiply to find the area!)

This Perimeter Area Song was fun to sing along with!

Hope you enjoy them as much as we did!
