Estimation 180 is an activity curated by Andrew Stadel, a teacher and Mathematics Coach in California. He created 180 different estimation challenges for his students and published his site, Estimation 180 in 2012. Since then teachers around the world have been using his lessons to develop students' number sense and reasoning. What is the learning? This routine engages students in number concepts, including relative size, comparing and ordering numbers, and benchmarks.
How do I facilitate Estimation 180 with my students? I begin by showing the students an image of a quantity. Supporting websites/videos/blogposts: Image from Dana Shiels Grade Three Classroom, Surrey, BC. Teaching to the Beat of a Different Drummer. Have you ever said or thought any of the following? “They just add all the numbers! It doesn’t matter what the problem says.” “They don’t stop to think! They just start computing as soon as they’re done reading the problem.” “They don’t even realize this is exactly the same type of situation as the problem we did yesterday!” Then you might be interested in trying out numberless word problems with your students. In essence, numberless word problems are designed to provide scaffolding that allows students the opportunity to develop a better understanding of the underlying structure of word problems. My Blog Posts I’ve written about numberless word problems at various points on my blog. Numberless Word Problems – This is the initial post I wrote about numberless word problems.
Problem Banks Below are banks of problems organized around the CGI problem types. Addition and Subtraction Problem Types Multiplication and Division Problem Types. Maths Ed Ideas: RESOURCES. Downloads: Extra Stuff to Do at Home Corridor Cards(Click here to return to the menu) A set of over 50 brochure style leaflets (more added regularly), full of mathematical problems, that are designed to promote the doing of mathematics for the sake of it, without that is any externally derived compulsion to do so, with no time-limits or deadlines or expectation of completion.
The leaflets are intended to be housed in school corridors for students to pick up a problem as and when and if they wish. It is important to note that they are not a replacement for homework, but rather a compliment to it. They are about promoting an unashamedly purist approach to mathematics with students, that we do mathematics in other words because we are curious about finding things out, because we find some things intriguing and want to find out more, because of the sense of adventure that comes with solving problems and, indeed, in doing so, finding more problems to solve.

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. In some cases, the labs in this book can replace corresponding lessons in your textbook. Other labs can be used to preview or review material that you teach in more traditional ways. You may download the whole book or individual sections for your non-commercial use. For a preview of some labs from the book, see: CircleTrig Geoboard Geoboard Activities.

MathNEXUS: Mathematics Portal. In the past ten years, you perhaps have enjoyed some of the problems included in the "Golden Oldie Section.
" If so, you now have a special treat in store! I now announce the release of a new website Olde Math Story Problems. It is a data base of more than 1600 historical problems, including many of those shared via MathNEXUS. The selected problems are connected with mathematical topics, skills, and concepts taught in secondary schools and colleges. The problems are categorized within several broad areas: Number Algebra Geometry Measurement Trigonometry Number Theory Probability Statistics Pre-calculus Calculus Logic and Proof Discrete Mathematics Recreational Mathematics Revealing international contributions and changing cultures, the problems span the full history of mathematics (2000 B.C. – 1940). Also, in response to numerous requests, each problem statement includes its source and varying amounts of solution commentary (I try to not spoil the problems for you).
