This week's challenge: 1/6 - 1/12: Ratios, rates, and proportions
Reminder of how to participate:
For the second quarter, the Challenge of the Week will involve doing problems on Khan Academy to practice for the SAT.
In order to participate, you will need to join the Khan Academy class called "Math Challenge" - class code is: 2VAMDW2W. Upon joining the class, you'll need to allow your SAT achievement to be shared with me. When you are ready to do practice problems, click on Courses (near the upper left hand corner), then select SAT under Test Prep (usually in the left most column). Click on Practice, select Math, go down the page to the Heading "Problem Solving and Data Analysis".
Each week, you will be given one entry for the ice cream ticket drawing for each question that you answer correctly for the week's topic.
