They’ve been working a lot with representing fractions as circles and as rectangles. They’ve done some basic addition with fractions. Most aren’t generally able to find equivalent fractions. Guinness World Record – The largest popsicle stick chain reaction. Guinness World Record – The largest popsicle stick chain reaction. Inside mathematics - a professional resource for educators / Polya. George Polya was a Hungarian who immigrated to the United States in 1940.

His major contribution is for his work in problem solving. Growing up he was very frustrated with the practice of having to regularly memorize information. He was an excellent problem solver. Early on his uncle tried to convince him to go into the mathematics field but he wanted to study law like his late father had. After a time at law school he became bored with all the legal technicalities he had to memorize. His first job was to tutor Gregor the young son of a baron. He was invited to teach in Zurich, Switzerland. Relief Teaching Ideas. A game for 2 or 3 players.

Each player chooses a colour pencil or texta they will use in the game. Players take turns rolling the dice, using the numbers that they rolled to draw the perimeter of a rectangle or square & writing the area in the middle of the shape. Game ends when players run out of room to draw. Winner is the player who has used the largest area/most squares. This game is an old favourite. Second Grade Math Japanese Lesson Study. Lesson study in japan. Max Ray at NCTM Ignite. Browse Talks. Gesturing with hands is a powerful tool for children’s math learning. Children who use their hands to gesture during a math lesson gain a deep understanding of the problems they are taught, according to new research from the University of Chicago’s Department of Psychology.

Previous research has found that gestures can help children learn. This study in particular was designed to answer whether abstract gesture can support generalization beyond a particular problem and whether abstract gesture is a more effective teaching tool than concrete action. “We found that acting gave children a relatively shallow understanding of a novel math concept, whereas gesturing led to deeper and more flexible learning,” explained the study’s lead author, Miriam A.

Tips For Teachers On Using Digital Technology. Geometry Is Worth The Extra Time… As I am sure many teachers can attest, there is a constant struggle each year between covering content and the precious amount of time we have to engage the students in learning.

Prior to the past two years in the classroom, this guilt always seemed to creep up most during our geometry units. I used to feel that once the students could find area, perimeter, and volume, we would move back into our fraction and decimal work because that always took SO much time to develop a deep, foundational understanding. While geometric representations such as an area model support the fraction and decimal work, it is still not the 2D or 3D unit work. Alyssa and India.. Productive struggle and aha moment.

All meaningful mathematics learning is imaged-based.

While there may be certain forms of mathematical reasoning that seem not to use imagery, most mathematical activity has a spatial component. If school mathematics is procedural, students may fail to develop their capacity to form mental images of mathematical patterns and relationships. It is well documented that students who reason from images tend to be powerful mathematics students. Further, we know that the ability to use images effectively in doing mathematics can be developed. When students are encouraged to develop mental images and use those images in mathematics, they show surprising growth.

Quick Draw is an engaging mathematical activity that helps students develop their mental imagery. The discussion of what they saw is a crucial component of the activity.

It’s been a great fall of 2014 – many states, many schools and many classrooms.

It’s been full of hope and optimism as I see many positive aspects of the Common Core era, more and better use of the incredible array of new on-line resources (see: ), and powerful forays into effective collaboration and coaching. But then there was a discouraging return to reality. I’m in a majority minority suburban school district with more than 12,000 students working with middle and high school teachers about strengthening the teaching and learning of algebra, and it’s the typical one-day one-shot PD.

So, I decided to make a few posters of these words to hang in my classroom.

This site provides an overview of the current application, information for Field Testers and Task ideas for teachers and parents. Background Information Current mathematics education software has been developed for the desktop/laptop paradigm of technology use where the mouse and keyboard are essential interfaces. Even software for interactive whiteboards (IWBs) does not take full advantage of touch-screen capacities because the mouse/keyboard interface is the default interaction mode. The touch-screen iPads also enable a much more intuitive interface suitable for young learners, allowing them to use their fingers and gestures to explore mathematics ideas and express mathematical understandings.

I presented these ideas at Twitter Math Camp 14 in the flex session on Saturday afternoon. Let me be clear, these great ideas belong to Peter Liljedahl and he deserves all the praise. I was fortunate to be asked to present at the Canadian Mathematics Education Forum about spiralling the curriculum with activity based teaching.

This is where Peter was a Keynote speaker. His idea of visible random groupings (VRG) and Vertical Non-Permanent Surfaces (VNPS) resonated with me. I felt it was an excellent teacher move to increase engagement in my classroom and to have learning be student centered. This post will probably be a little long as I would like to include some of his research as well. Visibly random groups & Vertical non-permanent surfaces. I have been trying to shift my Math classes toward activity- / problem-based learning. We still have individual practice days, but as much as possible I want them solving new, complicated problems in groups. Two ideas that I heard about at a meeting of the OCDSB Mathematics Department Heads have really changed how I do things in class lately: Visibly Random GroupsVertical Non-Permanent Surfaces Both ideas come from the work of Peter Liljedahl and have been gaining traction amongst OCDSB teachers lately, particularly in Mathematics classrooms.

I have seen quite a few posters to describe Webb’s Depth of Knowledge but I recently came across a set that is now my favorite. In particular, I love the bullet point lists that explain each of the levels as I believe that focusing on the verbs can lead to confusion (for example, “explain” can be level 1 through 4 depending on how it is used). Click the “Download Files” to download two PDFs: one has all four levels on a single sheetone has each level on its own sheet in a bigger size I got these posters via Alyda Mir who got them from Linda Evans.

When children are constructing multiplication they often start by needing to build a whole system of ones. So, if the context is “What’s 3 x 6?” , kids will count out 6, count out another 6, count out another 6, make sure they have 3 groups and to get the answer they go all the way back and count from 1 again. Eventually they begin to skip count and use repeated addition, and repeated addition usually builds into kids beginning to realize they can regroup groups.

So, something like 12 fifteens, kids will regroup the fifteens putting two together and turn 12 fifteens into 6 thirties. Cathy Fosnot, Ed.D. Cathy Fosnot - Doing Computations with Understanding.
