Make math fun! Planning a party gives students a real life opportunity to do various functions with decimals. I provide this worksheet to student pairs along with lots of halloween sales ads. The students can pick the things they want to buy to throw their virtual party. I do insist that they have at least 3 items in each category. You can vary this, but it ensures that students do have to do the decimal functions. Differentiation may be accomplished by ensuring that students choose more than 1 of an item or requiring them to fit their purchases within a tighter or certain high/low budget.
