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!


Spirit week and other updates.

Last week our school enjoyed spirit week.  Monday we dressed in our school colors, orange and black.  Tuesday we decorated our door to show our Kennedy School pride (please come by to read the reasons why we love the Kennedy School), and on Thursday we were joined by our fifth grade buddies from Ms. Bougas’s class to participate in some Kennedy School Trivia.  We finished up the week by wearing Patriots clothing to celebrate our New England Patriots.  It was a fun and exciting week!

In math, we have been continuing to sharpen our skills with addition and subtraction by using the number line and bar model.  We have also been finding the perimeter of squares and rectangles by using the formula perimeter equals length plus width plus length plus width.  Some children have even written books about “Peri the Perimeter Pet”!  The students have been using variables in equations to solve for the unknown.  We will be reviewing money, time, and rounding to the nearest ten and nearest hundred before our district assessment at the beginning of November.  Reminder: Always remember to show work (two different ways if possible), write equations, and write a sentence with your answer for word problems!

In English Language Arts we have been continuing our study of fiction.  The last two weeks we have been reading My Name Is Maria Isabel by Alma Flor Ada and we have been learning how to ask questions to further our understanding of what we have been reading so that we can have engaging conversations about the text.  Students have focused on asking a balance of “Right There” questions and “Author and Me” questions.  They have had clear behavior expectations when asking and answering questions with their groups and they have made significant progress over the last few weeks.  Group expectations include speaking and listening to my partner about my work, staying focused on my work for the entire time, and having the materials I need to complete my task.

In Social Studies each student has chosen a New England State to learn more about.  Each child will research their state, write a report, and do a presentation.  Much of the research will be completed in school.  Students will be receiving more information in the coming weeks.  We started our maps in class on Friday and the map is due Wednesday, October 21st.

Pool with resume this Monday and Wednesday is a noon dismissal for students.

I’ll leave you with a photograph from Friday.  The students participated in their first session of Playworks on the front school yard. We had a lot of fun, despite the chilly weather and everyone is already looking forward to our next session.


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!
