Linkfest for Thursday, March 27

• I got my master's degree at Eastern Michigan University. It makes me happy to see them on the web.
• Colorful related rates problems, and colorful descriptions of solution strategies.
• Turning multiplication table practice into a scrabble-like game sounds like a good idea to me.
• Teaching metacognition in math class.
• Fawn is teaching absolute value. (And giving us some great ideas.) And James Cleveland has a great inspiration, using estimation180 to help teach absolute value and analysis of errors.
• Math Munch collects other games like 2048.
• Mr.Honner once again finds a weird graph on a standardized test. It purports to be exponential, but it's not.
• Justin Lanier did a math circle on Celtic knots.
• Interesting puzzle - place the houses on the number line. I know there's some math here, but I haven't figured it out yet.
• Optimization, a calculus problem solved by dogs, ants, and light.
• Henri Picciotto has a nice visual Pythagorean Theorem proof.
