### Quote: Living Mathematics

Only dead mathematics can be taught where competition prevails: living mathematics must always be a communal possession. — Mary Everest Boole CREDITS: Today’s quote is from Mary Everest…

### A Tensegrity Icosahedron Model (or that cool collapsible thing from Little Man Tate)

A tensegrity icosahedron model, is one in which a 20 faced polynomial is outlined by free hanging struts, suspended in the tension of elastic bands. I'll be honest, I don't really know what its purpose would be. But, I can tell you, a tensegrity model of a icosahedron is the cool collapsible shape Fred Tate made in the 1991 movie Little Man Tate. And, not only is a lot of fun... ...to twist... ...and squish... ...and flatten, as you explore a three dimensional plane in motion... ...it turns…

Using snowflakes as a fun geometry project! This covers KS2, KS3, KS4

### Summer Fun 2014 - Sidewalk Chalk Paint Tape Resist - Marvelous Math Madness

Coffee Cups and Crayons posted a tape resist project using sidewalk chalk paint, a week or so ago. It looked like so much fun, I knew we were going to have to try it. As soon as I pulled out the chalk for the girls' starburst driveway drawings, and they started asking when we were going to make more chalk paint, the time seemed right to give it a try. We pulled a shape from the Marshall Hampton's Mathematical Coloring Book , settling on an "orthogonal hypercube projection", because it while…

### Summer Fun 2014 - Marshamallow and Toothpick Geometry - Finding the Cubes in a Hypercube

I did a little bit of research, and it turns out the octagon full of squares, and triangles, and stars which the girls had so much fun coloring in with sidewalk chalk paint... ...is really the outline of the shadow of a tesseract - not the glowing blue cube from The Avengers, or the 5th dimensional wormhole Meg Murray travels through in L'Engle's A Wrinkle In Time, but a 3-dimensional representation of a 4-dimensional hypercube, "that is to a cube, as a cube is to a square". I'm totally not…

### 3D Space Invaders

Class loved this one, they really got to grips with the idea and gained some understanding of perspective.

### How to make a Multiplication Tower

Do you have projects pinned that you’ve been meaning to do for years? Multiplication towers was one of mine. When I first saw them on The Map is Not the Territory I knew we’d all learn …

### Geometry Unit and Symmetry Activity

I really wish that I would have taken more pictures throughout our geometry unit. There are so many creative ideas out there to help solidify these concepts for kids. A few of the activities we did included: building various 2D and 3D shapes using marshmallows and toothpicks modeling various types of lines using pretzels (for the lines), M&Ms (for points and to create line segments), and candy corn (to show how the lines go on endlessly) creating foldables to remember different types of…

### Redirecting

Have you ever played with tangrams? Known to the Chinese as qi qiao ban: the "seven-board of cunning" puzzle was invented 1500 years ago, and still used today as a popular toy and in schools to teach trigonometry and geometry. It consists of 7 pieces, or tans, that are moved around to create a shape, often following an outline. The 7 pieces include five right triangles (large, medium and small), one square, and one parallelogram. The rules are simple, though the puzzles range in complexity…

### Math Curriculum Not Required

Is math a struggle? Why not ditch the curriculum and play some games? It's my opinion that using a math curriculum with young children is not required. Learning addition, subtraction, multiplication and division is just more fun with games and real-life experiences and that's the majority of what's covered during the elementary school years. Skills such as telling time, counting money, estimating, measuring and calendar skills are much easier to understand when they occur in the context of…

### Tangrams: The Seven Magic Shapes

Three Pigs, One Wolf and the Seven Magic Shapes by Grace Maccarone is a wonderful introduction for younger students to tangrams. The Tangram is an ancient Chinese puzzle in which one is to form a specific shape given only in outline or silhouette using all seven pieces, which may not overlap. In this book, the seven shapes make different characters or objects that further the plot. The tangrams in this book are not a single silhouette; the pieces are set slightly apart so that the young…
