The Helpful Art Teacher: SNOWFLAKES,MANDALA DESIGNS AND ROTATIONAL SYMMETRY: THE GEOMETRY OF ART. This mandala wheel has twelve fold symmetry, because the top wheel matches the bottom wheel twelve times.

In other words, this design is comprised of twelve identical slices around a central point. Each of these slices is 30 degrees of the whole (360 degree) circle (30x12=360). Hilarious Graphs Prove That Correlation Isn’t Causation. The High Line is a beautiful, bustling elevated park built on a former railway.

Planted with native grasses, flowers, and trees, it slices through the most valuable real estate in Chelsea, a neighborhood on Manhattan's west side. Over 20 million people have visited the park since it opened in 2009, making it one of the most popular tourist destinations—and economic catalysts—in the city. Elsewhere in the country, municipalities are eager to build their own "X" lines. It's tough to imagine that 20 years ago, developers wanted to demolish the railway. Now they're clamoring to build luxury condos, restaurants, boutiques, and galleries on the lots adjacent to it. Home - AMSI Schools. Overthinking my teaching. This page is a compilation of links to frequently requested resources.

They are arranged alphabetically by their subject, not their format. WIRIS editor demo - equations editor - educational mathematics. Digital Root Patterns. Digital roots provide some good opportunities for finding patterns.

They also reinforce the children's knowledge of their multiplication tables, and can be used to create some visual patterns. A worksheet with full instructions can be found below. This involves the children working out the digital roots of the numbers in each of the multipication tables, starting with the one times table, and progressing to the twelve times table. The following table shows the digital roots of each of the multipication calculations. Some of the lines have similar patterns. When you have worked out the digital roots of each of the multiplication sums, you can make some interesting visual patterns. Math Videos: Pre-Algebra 1 - Bay View Math. Limitless Applications.

Fractals - Hunting The Hidden Dimension [Full - Hd 720p] Fractivities : FractalFoundation.org. Fractivities are hands-on projects that teach fractal concepts in a fun, artistic way.

Students utilize their math skills in real-world applications and also work together as a team to create large fractal designs. With support from the Albert I. Pierce Foundation, our fractivities are aligned with common core standards in mathematics and English language arts so you can more easily incorporate teaching fractals in your classroom, combining science, math and art! Need help in choosing a fractivity? This summary page shows what grades each activity is appropriate for and what common core math standards they meet. National STEM Centre - Browse Collection. Introducing: The Great Inquiry Based Curriculum Mapping Project: a plea for collaboration. I’m kind of tired of working by myself.

I’m just not smart or creative enough to create an entirely inquiry-based curriculum. You know, the kind of curriculum where you pose an interesting problem to your students and let them attempt to solve the problem, and the teacher becomes more of a facilitator and intervenes, when necessary, rather than up-front, all the time. But I really do believe in that practice. Similarity to define sine, cosine, and tangent. Open-Ended Math Problems. TOKTalk.net. Linking Arts, Math, Perception and Emotions. Home.

Alan Schoenfeld in a seminal chapter from 1987 (What’s all the fuss about metacognition?) Discussed his observations of how undergraduate students solved problems. More than half, when faced with a non-standard problem outside a familiar context, followed the path illustrated in diagram 1. In this case, a pair of students read the problem, made a correct conjecture, but then got bogged down in calculations and ran out of time, even though they had the required knowledge to solve the problem.

Algebra - Solving Equations and Graphs - Growth Mindset Maths. Formative Assessment Lessons. Pythagoras’ Comma. In Problem 1 (Six Notes all Nice Ratios ) we explored a six point scale : shortest length to double that, with four lengths in between. In this problem the scale now has 12 points : shortest to double, with ten lengths in between. We are going to look for a closed and complete scale. Ratio inquiry. Dy/dan » Algebra: The Supplement.
