Marvellous Math!

Here’s an update about what we’ve been learning in math. Since returning from spring break, we have finished our unit on percentages and ratios. We watched the film If The World Were a Village to see what the world would look like if it had only 100 residents. Using that information, we displayed percentages in a few visual ways. We also used those skills to start a survey project. We interviewed 25 people and then have prepared posters that show the percentage of their answers. Finally, we created some artwork of our names to show the link between percentages, fractions, and decimal numbers.

With ratios, we learned when they are used in real life (for example, making quinoa: 1 part quinoa to 2 parts water! We also learned that many of us are not fans of quinoa). On top of that, we practiced identifying ratios from pictures and creating pictures from ratios.

Because of the importance of understanding fractions, we reviewed this week what we remembered about les fractions impropresles nombres fractionnaires, and how to order/compare these. Everyone showed great recall!

Next up: In mental math, we are practicing multiplying decimals by multiples of 10 (see the video below). We have also begun to learn about les régularités (patterns). For instance, today we practiced using les machines d’entrée-sortie to see what we remembered about identifying and following pattern rules. Here’s a game you can play at home to practice! 


If you’re looking for some more practice to do at home, it’s always wise to practice multiplication and division of larger numbers. We’ll be coming back to this very soon, in fact. (We do indeed use the standard algorithm – or the “old school” way. Check out this site to see how it’s introduced to promote conceptual understanding.)

Happy Math!


Persuasive Speeches

It’s time for our next type of speech! This time, we will focus on persuasion. The handout below should be in students’ speech duotangs. Presentations will begin Monday, April 17. Because the speech must be longer (between 3 and 4 minutes), students will have a good chunk of time next week in class to draft, practice and perfect their speech. They will still, however, need to complete some work at home.

Here is an example of a persuasive speech that we watched and discussed in class. Notice how she appeals to the audience’s emotions and uses facts and logic to support her argument.
