  • Take Apart Day!
    Today, our Grade 3 class helped our Kindergarten Buddies with Take Apart Day. Students helped their buddies use tools such as screwdrivers, to take apart a variety of electronic devices. Afterwards, our Grade 3 students reflected on their Learning Skills.

  • Probability Experiment using 2 Number Cubes
    Students conducted a probability experiment by playing a game. Students placed their marker on a number from 1 to 12. If they rolled that sum using 2 number cubes, they moved their marker up the game board. Students quickly developed their own strategies for placing their marker. They realized that it was impossible to get the sum of 1 using 2 number cubes so they did not place their marker there (some students even crossed the number out on the game board). Students also realized it was unlikely they would roll a 12 since there was only 1 way to make that sum using 2 number cubes. Most students placed their markers on the middle numbers since those sums could be made in a variety of way (6 could be made by rolling a 3 and 3, 4 and 2, 5 and 1). 

    After students played the game, we discussed their strategies and the probability of each sum occurring. To further demonstrate this, we used a probability website to simulate rolling 2 number cubes 132 times. It generated the tally chart below which validated students observations from the game.

  • Rock Hyraxes- Finding Key Words & Summarizing

    Students have been learning to find keywords in articles and to write summaries using those keywords.

    First students picked out the keywords from the article on rock hyraxes. The different parts of the article were covered up on the projector. I slowly uncovered the article. First the title, then the sub headings and photo captions and finally the paragraphs. Each time students picked out 1 or 2 keywords. Keywords are words that are repeated, that capture an important idea or are easy to visualize. 

    Time lapse video of the article being uncovered:

    Below is the article completely uncovered:

    Below is a list of keywords that a student made from the article:

    Next we started a $2 summary together. A $2 summary is a way of summarizing an article in a couple of sentences. The goal is to use as many keywords as you can but keep the summary to around 20 words. Each word you use in your sentence costs 10 cents however the topic words, rock hyraxes, were considered free to use.

    Together we wrote the first part of the summary which totaled $1.20. 

    Afterwards, students logged into Google Classroom and made their own $2 summaries using Google Slides:

  • The Ants Go Marching Problem
    Today students worked on a problem inspired by the children's song: The Ants Go Marching.

    First students listened to and sang the song (the song is part of our primary musical, so students are very familiar with it). As students sang the song, they acted it out. First we had 1 student marching (1 by 1). Next we had 4 students marching (2 by 2). Finally we had 9 students marching (3 by 3).

    Finally, students were introduced to the problem below. In partners, they worked enthusiastically to solve the problem.


    The problem presented to the students:

    I loved the variety of strategies students used to solve this problem!

  • Math Eyes Math Walk
    Today students used their math eyes to find and take pictures of math in our school yard. Afterwards, they made picture collages and inserted them (by themselves) into a class shared Google slideshow.
