This morning in Math we continued learning about ratios (les rapports). Ratios are a comparison of quantities. We use ratios almost every day, especially in the kitchen! We see ratios when we mix frozen orange juice, cook rice and bake a cake! Specific ratios ensure of juice won't be watered down, our rice won't be too mushy and our cake won't be dry!
And, because there's no better way to kick off a new Math concept than with a sugary cereal treat, we opened up a box of Fruity Os to practice our ratio-writing skills!
We each got a small cup of Fruity Os and counted out 20. We then worked to answer specific questions comparing one colour of "O" to another. Mme Careen tried to trick us by asking us to write a ratio of how many BLUE Fruity Os we had. Silly Mme! There is no such thing as blue Fruity Os! :)
Our next step - which we will continue working on tomorrow - will be to find the percentage of each colour represented in our group of 20 Fruity Os. Because percents are fractions over 100 (and not over 20 like the fractions we had written), we'll have a bit of Math thinking to do!
Ex: Out of her group of 20, Mme Careen had 4 yellow Fruity Os. What percentage of her Fruity Os are yellow?
In addition to learning about ratios, this activity is also getting us ready to review and tackle fractions and equivalent fractions next week! Who knew there was so much Math hiding in a box of Fruity Os ?!

Agenda items:
1. Fun lunch - tomorrow!
2. Congratulations and Thank You! Our class brought in 73 non-perishable food items and a $25 donation in support of this year's SOUPer Bowl! Hooray! A final school-wide count will be announced early next week.
Way to go, les chevaliers!
