Problem of the Week for Grades 3 and 4: Would you rather have one half of a chocolate bar that weighs 280 grams or one half of a chocolate bar that weighs 460 grams? Draw a picture of the candy bars to show why.

Problem of the Week for Grades 5 and 6: You can find the approximate temperature in Celsius by subtracting 32 from the temperature in Fahrenheit, then dividing that number by 2. A recipe for pecan brittle needs to be heated to 300°F, but your candy thermometer only measures in Celsius. Find the temperature in Celsius to which you should heat the candy.

Problem of the Week for Grades 7 and 8: Polly is selling candy bars for a fund raiser. She sells caramel chocolate bars for \$3 and peanut butter chocolate bars for \$4. If she sells twice as many peanut butter chocolate bars as caramel chocolate bars and gets \$44 in total, how many of each kind of candy bar did she sell?

Problem of the Week for Grades 9 and above: A cylindrical chocolate peppermint cookie has a layer of dark chocolate cookie, a layer of peppermint creme on top, and layer of dark chocolate all over the whole thing. The cookie layer is 2mm thick, the peppermint creme layer is 3mm thick, and the chocolate layer is 1mm thick on all sides. If the whole cookie is 52mm across, then what is the volume of the chocolate peppermint cookie?
