Edible Problems for Ratio, Rate and Proportion
On Friday, October 14, we will have a "Ratio Party" with the Grade 8 math class. Students are to bring an edible ratio or rate... With their food item, they must include a problem for ratio or rate and provide for the class to solve. Students may go in partners for the assignment. Due to food allergies, please DO NOT bring items that contain NUTS.
* If students do not want to bring an "edible ratio", they must write a Ratio or Rate problem and submit it to Ms. SM on Friday, as it is an assignment. ANSWER KEYS MUST BE INCLUDED. PROBLEMS MUST BE TYPED OR HANDWRITTEN NEATLY.
** Each problem must reflect the number of people in your group. It's a ratio... 1 person - 1 part to the problem, 2 people in the group - 2 parts to the problem... Make your problem include ratios, rates and proportions... Make sure it makes sense and is "solvable".

** REMINDER- UNIT 2 RATIO, RATES AND PROPORTION TEST MOVED TO WED, OCT. 12.
