  • Estimating and Measuring Length and Collecting Data using Google Forms
    Students have been estimating and measuring in cubes.

    Task: Students were tasked to estimate and measure 3 objects from the classroom using cubes. They were also asked to identify whether their estimate was: too short, too long or just right.



    When done, students entered in their data on an iPad using Google Forms:

    Consolidating the lesson: When done, we examined the data that was collected. 

    First we looked at students' estimates. We noticed that their estimates were very accurate.

    Next we looked at the length of objects. The most popular length (or mode) was 4 cubes long.



    Finally we used Google Sheets to order the objects from smallest to greatest. The smallest object measured (Lego) was 1 cube and the largest object measured (filing cabinet) was 53 cubes!

  • The Power to Connect
    This week I introduced our first reading power. Reading Power is a terrific resource that teaches various reading strategies to help students understand (or comprehend) what they read.

    The reading power I introduced was called the power to connect. Making connections while we read is something we do naturally as we get older. To explain the power to connect I read them the below passage to help explain why making connections while we read is actually quite remarkable. Over the next few weeks we will be working on making meaningful connections to texts we read in class.


    We also related the Power of Connect to the book: Once Upon an Ordinary School Day by Colin McNaughton

    Students were asked: Why is it, in this book, when everyone in the room was listening to the same piece of music, everyone was thinking something different?
    -We discussed that everyone is unique and therefore makes different connections from the music to their life stories.

  • Dash (the Robot) Bulldozing Challenge!
    Yesterday, students completed a STEAM task involving coding Dash the robot. The task was to code Dash to remove as many balls as possible from a hundred's mat.

    This activity linked to the curriculum and learning skills in many ways:
    • Students worked together to complete the task, often troubleshooting together when their code didn't work as expected (LS- Collaboration)
    • Programming movement on a grid (Geometry)
    • Right, acute and obtuse angles (Geometry)
    • Area-the number of squares that contained balls compared to those that were empty (Measurement)
    • Students were told that for every 20cm they programmed Dash to travel, it would move one square on the grid (Measurement)
    • Dash pushing the balls off the carpet (Science- Forces)
    • Friction-The carpet slowed the distance Dah travelled so in fact each square measured less than 20 cm(Science-Forces)
    First we discussed what a force was (a push or pull) and I showed them some robotic videos from Boston Dynamics as inspiration.  

    Next students were presented the task.

    Then students were given grid paper that showed the layout of the balls on the mat. They were told that if they programmed Dash to move 20cm, that was the equivalent of moving one square on the grid. Students planned a route for Dash on the grid paper before coding their route on the iPad app.

    Finally, when students were satisfied with their code, they attempted the task. Students were allowed up to three attempts. This gave students the opportunity to analyze Dash's performance and make modifications to the code before the next attempt. It is interesting to note that almost every group was able to improve Dash's performance in subsequent attempts.



    Afterwards, students reflected on their Learning Skill using Google Forms. They were asked to reflecton the following cooperation skills:
    I shared and took turns coding Dash with my partner.
    I listened and appreciated my partner's ideas. 
    I showed teamwork with my partner. 
    I used kind words with my partner.

  • Seeing Numbers Visually
    This week we discussed that powerful math learning happens when we think about numbers as symbols while also visualizing and drawing the numbers.

    Students looked at the drawing below. They were asked what number did each drawing represent  (they visually represent the numbers from 1 to 21) and what did see when they looked at that number.

    We also discussed how we saw the number (for example 9 is made up of groups of 3). Students were then asked to colour code their math thinking. Many students broke down the number into factors (for example 12 as 3 groups of 4). Others saw shapes in the numbers (for example 16 looks likes 4 squares).


    We also looked at this cool website that displays numbers visually counting from 1 to 1000 and beyond!

  • Dreamers
    Today we read the book Dreamers by Yuyi Morales. Yuyi Morales writes about a mother and her child who immigrate to another country where she did not speak the language. This beautifully illustrated book is on the Global Read Aloud list for 2019.

  • Google Accounts and Google Classroom


    This past week, students received their SCDSB Google Account login information. Using this information, students were able to login into Google Classroom. Google Classroom is a private digital learning platform where students can interact, collaborate and complete assignments using the Google Suite of Apps (for example Google Docs, Google Slides etc). Many applications, such as the stop motion app on the iPads, also export directly to Google Classroom. Google Classroom is widely used in the Junior/Immediate (and higher) Grades and I feel that they will benefit from becoming familiar with it now. Their login is written in the front of their agendas.

    Best regards,
    P. Johnson
