Artifact 8


Bubble bubble, toil, and trouble ratio activity

This is the activity I created for my first Learning Activity Presentation. I made it Halloween themed because I presented towards the end of October. It involves adjusting a recipe based on serving size, both a practical and important skill.

I set the target grades as 6-8 for proportional relationships under the Number Sense and Numeration strand. The reason I gave a range is because the activity can be adjusted for difficulty depending on the numbers you use in the recipe (I aimed for ones that would be really tidy, but you can change it any way you please).

I will certainly use this in the classroom not as a diagnostic activity, but will use it only after students have become more comfortable with ratios. It went well during my presentation, so hopefully it will go smoothly in the classroom too!
