  • The School Fair Necklaces Problem
    Today students were challenged to solve this interesting problem from Youcubed.org. Students had to figure out all the combinations of necklaces that had 4 yellow and 4 red beads on it. Also, each necklace must be symmetrical (see picture below). 

    Students took a variety of approaches to solve this problem. Some used pattern blocks, tiles or cubes where as others represented the necklaces using coloured squares. Also one group of students represented the beads using letters (y and r) whereas another group of students represented the beads using numbers (1 and 2). Students found a total of 6 combinations. One of the strategies that students discussed was finding one combination, then swapping the colours of the beads to find a second combination. What great math thinking!

  • Geocity- Applying Geometry Knowledge
    Over the past week, students have been using their knowledge of geometry to create a city. Each student was responsible for one section of the city (tourism district, business district, public works district, city living district and many more). When completed, they put all of the districts together to create one large Geocity!

    Afterwards, students made digital posters advertising their city as well as movie trailers promoting their city.

  • 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.
