Mini eco. 12 Visualizations That Will Change the Way You View Scale in Your World. Scale is a simple concept. From a very early age, children know about big and small, heavy and light, more and less. Extreme scales, however, are another story. Try to imagine, for example, the size of the universe… or \$1 trillion made up entirely of dollar bills. Exactly. Below are 12 visualizations that try to show things at extreme scales. 1. 2. 3. 4. 5. 6. 7. 8. 9.

Humans all fit within a small range of sizes, weights, and lifespans, and the quantities we deal with typically fit in small ranges as well.

» Giddy With Excitement! Grades 1 and 2 at Ancaster Meadow School. Feb1 Ever since I started focusing on math this year, I’ve started to love math in a way that I never did before. I think that I’m having as much fun learning math as my students are, and I’m so glad that we can learn together. This week though – even though it’s only Tuesday – has been incredible!

This is our school’s Math Week, so today, I set-up some different math centres that had students writing and talking about math. At one of the centres, students were making various shape pictures and completing various tanagrams. You can almost hear me chuckling in the background because I’m just so excited by what this student figured out. The best thing though is that this video was just the start of so many amazing conversations about math. Just listening to what the children discuss show me what the students know and what they still need to learn (I think it’s time to introduce the parallelogram). Aviva. Maths. Order of Operation Songs. Written by: Amanda Smith • edited by: Trent Lorcher • updated: 2/14/2012 Do you remember your favorite song from 10 years ago? Do you remember it word for word? That is the beauty of using music as a tool in learning.

By putting the steps of the order of operations to song, your students will have a blast while increasing their memorization of the concept. Order of Operations SongsThe order of operations is a very important concept in elementary math education. Teaching Tools for the Order of Operations Need help finding creative ways to engage students in learning the Order or Operations?

Khan Academy. Math Mayhem. Teaching Fractions with Sketchpad | Sine of the Times. Share A quick quiz: How many fractions are there? Fractions like 13/37 and 1/100 rarely appear in elementary mathematics curricula. This may sound like an absurd question, but in the context of elementary mathematics curricula, it makes a lot of sense. Think about it: Children encounter fractions like 1/2, 3/4, and 2/6 all the time, but do they ever see 1/100, 31/90, or 499/500? Unlikely. So when it comes down to it, children encounter relatively few fractions. The NSF-sponsored Dynamic Number project at KCP Technologies (the sister company of Key Curriculum Press) is creating Sketchpad activities for grades 2–8 that focus on number, operation, and early algebra. In several of our activities, we provide students with area models of fractions in which they can change the numerator or denominator of a fraction and immediately view its corresponding picture, represented as shaded parts of one or more circles.

With some trepidation, we entered 100. The video below starts with 1/2. Graphing Stories. Or: Best Lesson Ever Or: Why It’s Nice To Have Some Totally Extraneous Skills Or: Skip The Blah-Blah. Downloads At The End. The Blah-Blah I know this isn’t new. “Give me a graph of what happens to a bouncing ball over time.” “Show me what happens to your height as you grow up.” “Give me a graph of your marriage odds for each year of your life.” “Et cetera.” This idea that we can describe things that happen with mathematical graphs isn’t new, nor is the idea that this is an effective introduction to a linear unit.

I went out and taped ten events. I put a handout on every student’s desk with a graph ready for each event. I played each event and then paused the video. The students started scrawling approximations of my movement and realized quickly that they couldn’t remember when I hit the next flight of stairs (was it after four seconds? But I pressed play again and the same event played out, only at half speed. All this time I walked from desk to desk, stamping graphs I liked. Download Options. Plain. Maths iPad Apps.
