In keeping with the holiday spirit, I will be milling around the room bestowing glad tidings upon all whom I see. However, in keeping with the competitive spirit of the classroom, there will be a prize for the winning pair. Desks are arranged in pairs. The pair that comes up with the correct calculation first will be a winner. Each group is given a copy of both worksheets.
Students begin work on the price index calculation.
Prices of products are given on a per unit basis. The same logic follows for the Eight Nights of Chanukah worksheet. Proportionally, the actual calculation of the index doesn't really vary that much if they make the math error noted above, but I strive for complete accuracy to add to the fun of the contest. I usually have the winning pair go to the board to take the class through their calculation. Prizes are awarded and we leave for holiday break.
