Grade 7 Mathematics Lesson Plan ![]()
Lateral Thinking and Logic PuzzlesI encourage you to use any reference materials you think might help on the following 10 puzzles. I have deliberately stored the answers on a separate page to keep you from looking until you are ready. For the first four puzzles, pretend that you are an alien who had managed to learn the English language, but you do not know what significance the days of the week have. On which day of the week would you assume ...1. You would cook a meal.
2. You would get paid.
3. You would get married.
4. It would be unusually bright.
5. If there are four empty seats in a movie theatre, how many combinations are there for the number of ways four (4) people could sit in these seats?
6. There are 10 socks of each of the following colors in a drawer: blue, green, red, yellow, and white, for a total of 50 socks. If the socks are randomly distributed in the drawer (i.e., not in pairs or any other grouping), and you are blindfolded, what is the minimum number socks you must draw from the drawer in order to be certain you have at least two (2) socks of the same color?
7. If you are in the same situation as in the preceding problem, how many socks must you draw from the drawer in order to be certain you have at least two (2) socks of different colors?
8. If none of the following statements are true, who can we conclude broke the vase?
Mike: Sally broke the vase.9. Make a word from boas that can be used to keep you clean.

April: Tom, Mike and I could not have broken the vase.
Chris: I did not break the vase.
Erik: Mike broke the vase, so Tom and April could not have.
