Illuminations: Trigonometry for Solving Problems

The resources provided on this site from the National Council of Teachers of Mathematics include two trigonometry square activity sheets with which students can use to apply trigonometric values to common angles.  With the angle of elevation activity sheet students solve two problems, one by using right-angle trigonometry, and the other using the law of sines.  The last activity, the angle of declination, uses the law of cosines.  This can be a small group activity and answers may vary, but the discussion of each small group in deciding on their “correct” answer is invaluable.

EDSITEment: Evaluating Eyewitness Reports

Sept. 26

  Eyewitness accounts are often notoriously unreliable.  Use this lesson plan from EDSITEment to evaluate eyewitness accounts about the Great Chicago Fire of 1871.  Historians often use such accounts as part of their research into events, but they must look at them with a jaundiced eye, and not base all their historical interpretation of evidence on what one or two eyewitnesses say.  Students compare newspaper reports with eyewitness accounts to find how the understanding of events can be changed by tincture of time. The other event students look at is a diary by a sixteen-year-old girl who wrote about the …

National Geographic Education: A River Puzzle

Sept. 25

  Rivers are an important natural resource.  How a river is used and how humans interact with the river changes as it progresses through its watershed.  With this lesson students will think about how land is used along a river, and what the impact of that use is not only on humans, but also on the environment.  Included on the site is a puzzle showing many different uses.  Students start out with the source and mouth on opposite ends before filling in the many uses as the river flows toward the mouth.  This is a great hands-on learning exercise that …

National Punctuation Day

Sept. 24

    Today is a day that should be dear to every writer’s heart.  Punctuation gives writers the power to guide the reader to the intent of the writing.  Correct punctuation could save someone’s life.  For example, grandpa would surely be at risk if you wrote “let’s eat grandpa” rather than “let’s eat, grandpa.”  Perhaps the most misused punctuation mark is the apostrophe, but commas might come in a close second.  This site, dedicated to the yearly celebration of punctuation, has information about each form of punctuation, examples of BIG mistakes, and ways you can celebrate. Perhaps you can think …

CK-12 Foundation: Descriptive Statistics

Sept. 23

  Statistics is a large field of study.  A small part of that deals with descriptive statistics, which can be used to show a central tendency when summarizing hundreds of pieces of data. Learn how to figure the mean, mode, and median which can be used to find a central tendency.  You will also learn about range and how it is calculated to find the variation in the sample.  Practice what you know by clicking on the link to a BBC game.  After that, see if you can answer the review questions.

St. John: Guide to First Aid for Bleeding

Sept. 22

  In honor of the invention of the Band-Aid on this day in 1920, here’s a review of first aid procedures for different causes of bleeding.  A Band-Aid might not help with any of them initially, but knowing how to treat various sources of bleeding is important.  Some of the pictures are graphic, especially the ones on puncture wounds or amputation, but if that bothers you, just close your eyes until you can scroll to the important descriptions of what to do.  Because this is a site from New Zealand, the emergency number there  is 111.  You, of course, know …

EconEdLink: ‘Be All You Can Be’…For Minimum Wage?

Sept. 18

    Although this lesson plan from the Council for Economic Education is about five years old, the information contained in it is still timely.  Students look at how military strength has changed since the end of the draft.  I’m sure that will seem like ancient history to many of them.  By examining pay tables, housing benefits, and other benefits of being in the military, students can look at the incentives the military offers despite the fact the monthly pay for a private is so low.  Are these incentives enough to make the military an attractive alternative to private employment? …

Not only will they learn what a constitution is,  but by entering the Reading Room, they will find out from James Madison himself what went into writing our Constitution and why he is called the Father of the Constitution.  There are two activities for students to complete to …
