MasterMath.info: Middle School Math Lessons Free fraction videos online Enjoy free online math videos on these fraction topics: (Fraction videos, part 2, are on this page.) The videos are recorded in high-density (HD) and are viewable both here as well as at my Youtube channel. These videos are usable for students, teachers, and parents. You can use them... To learn these topics yourself (if you're a student for example, or an adult needing a refresher)As lesson plans for teaching these topics. The videos match the lessons in my book Math Mammoth Fractions 1 (Blue Series book), or the lessons in chapter 5 of Grade 5-B (Light Blue series). Mixed numbers to fractions and vice versa I explain both the visual models and the shortcuts for converting mixed numbers to fractions or fractions to mixed numbers. To convert a mixed number to a fraction, divide the whole "pies" into pieces (the same kind of pieces as what the fractional part indicates), then figure out how many pieces you have. Adding and Subtracting Like Fractions Equivalent fractions - split the pieces!
Geometry Labs Geometry Labs is a book of hands-on activities that use manipulatives to teach important ideas in geometry. These 78 activities have enough depth to provide excellent opportunities for discussion and reflection in both middle school and high school classrooms. Middle school teachers will find many labs that help prepare students for high school geometry by getting them to think visually and become familiar with fundamental concepts, figures, and vocabulary. Teachers of high school geometry —whether traditional, inductive, or technology-based— will find many labs that approach key topics in their curriculum from a different point of view. You may download the whole book or individual sections for your non-commercial use. For a preview of some labs from the book, see: The book uses tangrams, pattern blocks, cubes, mirrors, plus two manipulatives I designed, the CircleTrig Geoboard, and the Geometry Labs Template.

AIMS Puzzle Corner: Free Math Puzzles This week’s Puzzle Corner activity is a magic trick with a mathematical, as well as a slight-of-hand, component. I first came across this trick in one of Martin Gardner’s many books on recreational mathematics. I liked it so much that I have been stumping students, friends, and family members with it ever since. In order to make this trick work, you will need to practice it by yourself until the moves (illustrated at bottom) become automatic, before trying it out on someone else. Its success, like the success of many magic tricks, depends on diverting the audience’s in this case, your students’ attention. You can’t do this if you are uncertain of all the moves and take too much time making them. You will need at least three cups to perform this trick. Begin this trick by explaining that the goal is to get all three cups facing up after making exactly three moves. Next, invite one of the students who was watching to get all the cups facing up in three moves. Performing the trick: 1. 2.
