Number Tricks

Ms. Arroyo asked the class to see if they could find the sum of the first 50 odd numbers. As everyone settled down to their addition, Terry ran to her and said, “The sum is 2,500.” Ms. Arroyo thought, “Lucky guess,” and gave him the task of finding the sum of the first 75 odd numbers. Within 20 seconds, Terry was back with the correct answer of 5,625.

How does Terry find the sum so quickly?

Creativity : Engineering Challenge : Kite

Engineering challenges are fun activities that are frequently assigned to students in physics or engineering classes, but they can easily be used outside of these venues. An engineering challenge usually has a simple goal and some rules about what sorts of materials you are allowed to use. These are great ways to get people thinking creatively and to foster teamwork and competition. Try an engineering challenge at a birthday party, office outing, scout meeting, or any other gathering where you want to have fun and exercise your creativity.

The objective in the Kite challenge is to construct a kite out of a sheet of paper, plastic drinking straws and tape. The winning kite will be the one to reach the highest altitude with a fixed length of string. If you don’t have a windy place nearby, you can allow the contestants to run with the kite to simulate wind. To measure altitude, a simple angle altimeter can be purchased at many hobby stores, or you can create your own with a protractor, string and a small weight.

Memory : Review

No matter how well you learn something, if you never access that information you will probably forget it. If you want to remember something, you need to review it from time to time to keep it fresh in your mind.

Review can also be very helpful immediately after learning something, because it can help solidify the important facts and make it easier for the brain to identify what to remember. You can use this to your advantage by making sure that you set aside some time at the end of a study session to review what you have learned. Just going over the main facts in your mind will be very helpful. You might also consider doing this after a class lecture. Take a few minutes to review your notes and go over the instructor’s main points.
