  • Dance for Primary Musical
    I am posting our class dance for the musical in order for students to listen to and watch (and hopefully practice). Our dance portion starts at 1:55 of the video.

  • Coding with Scratch
    This week students were coding with the programming language Scratch. Earlier this year, students explored the block coding capabilities of the Scratch language. This week students used activity cards to help build their programming and coding skills. Many of the activities reflect our geometry unit (for example, coding different types of angles).

    In this activity, students coded the mouse to move and turn in right angles. Here is a link to the rest of the activity cards (if students would like to explore them at home).

  • Creating a Drawing Accessory for Dash the Robot
    This week grade 3 students broke up into teams to complete the following STEAM challenge. After they completed the challenge students reflected and self-evaluated their leaning skills for this activity (Responsibility, Organization, Self-Regulation, Collaboration).

    Students worked together to build a structure to hold a marker. This accessory would allow Dash to become an artist!

    Students used Lego and up up 4 rubber bands. Students used their knowledge about structures and stability when designing their accessory.

    Students tested and revised their designs. Students used Dash to draw geometric shapes (circles, right angles, squares, hexagon). Students also coded Dash to draw using the Blocky Coding App.

  • Finding Angles and Making Collages

  • Right Angles
    The goal for this math lesson was for students to understand what a right angle is and to be able to identify right angles in shapes. 

    Step 1
    Students were shown items one at a time in a YES group and items in a NO group (concept attainment). Students were only told that the YES group had something all in common that the NO group did not have. They were also told that the sorting rule for the YES group had nothing to do with size or number of sides of shapes.

    Step 2
    Students were told to keep their predictions of the sorting rule to themselves. They were also told to be prepared to make new predictions if their sorting rule no longer fit the objects being shown.

    Step 3
    Students were asked to raise their hand if they had a prediction of what the sorting rule was. They were then asked to whisper their prediction to another student who did not have their hand up. Afterwards, I showed several more YES and NO examples.

    Step 4
    Finally students were shown a list of TESTERS. They voted using their thumbs (up or down) whether the object belonged in the YES or NO group.

    Students then had the opportunity to discuss and share their predictions with the class. Students were quick to realize that the YES group had SQUARE CORNERS (right angles) and the NO group didn't. Students also described the YES group as having corners that looked like the letter L.

  • Congruent Shapes
    Students have been learning about congruent shapesShapes are said to be congruent if one shape can become another using reflections (flips), translations (slides) or rotations (turns). The shapes are the same size and the same shape.

    Step 1: Students played the Yes/No game (concept attainment) to try and figure out what the yes shapes had in common that made them different from the no shapes. Each pair of YES shapes were this math concept and each pair of the NO shapes were not that math concept.

    Step 2: Students used testers to see whether their prediction was correct.

    Step 3: After the testers, students made predictions of what math concept the YES pairs had.
    Some sample  responses:
    -The yes shapes are the same size
    -If you turned a shape, you can fit it over another shape
    -The shapes are the same size and same kind

  • Pixel Art and Finding Area
    Students created pixel art using Google Sheets then found the area of each colour of their design.

  • Pasta Bridges
    Some pictures from our class building and testing (with up to 1 kg weights) of pasta bridges.

  • Minecraft Perimeter Problem
    Today students were given the math task below. The big idea was solving perimeter when you are not given the specific lengths of every side (but have enough information to determine the length of the missing measurements using math).

    Students were very engaged in completing this task. Lots of great mathematical thinking:
    • Labeling sides with the measurement once they had determined what it was.
    • Showing calculating the perimeter using addition sentences and multiplication sentence (for the perimeter where the sides were all the same length).
    • Showing how they calculated the length of a side which measurement was missing.
    • Using arrows to help explain their mathematical thinking.

  • Tower Building STEAM Task
    Today students learned about strong and stable structures and built a tower (made of pasta) that supported a marshmallow on top.

    First students were shown this video and we discussed how to make a structure strong and stable.

    Then students were introduced to the STEAM activity. We also discussed the learning skills that applied to this task (students completed a self evaluation of their learning skills after the task).

    Finally students built their towers. Afterwards, they recoded a video (using Flipgrid) on how they made their towers strong and stable as well as what they might do differently if they were to construct another tower.
