Subject: math class opener trick

One of the opener "tricks" I use with my 9th grade Algebra students was this: You need a calendar big enough for the class to gather around. I have them go up to the calendar and quietly chose 4 dates off the calendar that form a perfect square. The add the dates together and give me the total only. Then, using my magic algebra formula, I solve it and tell them the four dates they chose. If you use: n = 1st date (n) + (n + 1) + (n + 7) + (n + 9) = the total given to you Plug back in to arrive at the four dates chosen from the calendar. I use this at the beginning of distributive property, but can be used in several areas or just for fun. KIM
