FLI - Future of Life Institute Numberless Word Problems | 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! 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 Other Blog Post Collection Would you like to hear how other educators have used numberless word problems? If you write a blog post and would like me to include it here, just fill out this form. Like this: Like Loading...

Centauri Dreams — Imagining and Planning Interstellar Exploration Desmos Art: A Definitive Guide to Computational Sketching | Math Vault If you’re of the type who enjoys playing around with graphing calculator, then you might be interested in the so-called Desmos Art. These are basically pictures and animations created in Desmos primarily through the clever use of equations and inequalities — among other features such as tables, animating sliders and regression models. Indeed, if you go to this official staff pick page, you should see that a whole bunch of creative artworks were already being created — anything from cartoon characters, landscape to logos and portraits. But here’s a problem: when you reach a Desmos artwork page, you get to see the end-result with all the equations and inequalities, without necessarily having any clue about how the sketching process comes about from the beginning to the end. Why does this weird-looking equation pop out from nowhere?

Weird things start to happen when you stare into someone's eyes for 10 minutes Giovanni Caputo recruited 20 young adults (15 women) to form pairs. Each pair sat in chairs opposite each other, one metre apart, in a large, dimly lit room. Specifically, the lighting level was 0.8 lx, which Caputo says "allowed detailed perception of the fine face traits but attenuated colour perception." When the 10 minutes were over the participants filled out three questionnaires: the first was an 18-item test of dissociative states; the other two asked questions about their experience of the other person's face (or their own face if they were in the control group). The participants in the eye-staring group said they'd had a compelling experience unlike anything they'd felt before. Caputo thinks the facial hallucinations are a kind of rebound effect, as the participants in the eye-staring group returned to "reality" after dissociating. Other clues come from prior research by Caputo and others. Caputo, G. (2015).

Home | Math Vault The Brains Blog | Since 2005, a leading forum for work in the philosophy and science of mind s Blog – Mrs. Cathy Yenca | Happenings from my real-life 21st-century mathematics classroom Fun Fact: That’s the Capital of Texas Highway, which takes you right to my house! Every time I try to sit down and compose a blog post about last week’s Apple Distinguished Educator Global Institute… I can’t. It’s not that I don’t want to! I *literally* can’t type the words. Even with every letter in the alphabet and every word in the dictionary, anything I attempt to share here will fall short. How can I convey here the feeling I had when I walked into the first general session, realizing that nearly 400 educators with hearts like mine from nearly 40 countries were gathered there? Through workshops facilitated by ADEs and Apple staff, we learned so much from the best of the best at Apple. We collaborated in teams, brainstorming and offering feedback on our passion projects. A few of many, many highlights for me include: Stephanie Thompson’s 3-Minute Showcase: Using ‘Equity Maps’ to empower students with relevant, accessible, and meaningful data.
