9 Strategies for Motivating Students in Mathematics | Edutopia Motivating students to be (enthusiastically) receptive is one of the most important aspects of mathematics instruction and a critical aspect of the Common Core State Standards. Effective teachers should focus attention on the less interested students as well as the motivated ones. Presented in this blog post are nine techniques, based on intrinsic and extrinsic motivation, which can be used to motivate secondary school students in mathematics. Extrinsic and Intrinsic Motivation Extrinsic motivation involves rewards that occur outside the learner's control. However, many students demonstrate intrinsic goals in their desire to understand a topic or concept (task-related), to outperform others (ego-related), or to impress others (social-related). With these basic concepts in mind, there are specific techniques which might be expanded, embellished and adapted to the teacher's personality and, above all, made appropriate for the learner's level of ability and environment. 1. 2. 3. 4. 5. 6.

what's shakin An earthquake is a sudden release of stored energy. Earthquakes occur when slow but powerful tectonic forces cause stress to build up in the Earth’s crust. When the stresses get large enough, slippage is triggered along fractures in the rock known as faults. The sudden slipping motion along a fault causes vibrations known as seismic waves to form and travel away from the zone of slippage. Several meters of slip along a large fault causes a major earthquake; a few centimeters of slip on a small fault (perhaps the size of a soccer field) would cause a small earthquake. Seismic waves that travel through the rocks of the Earth’s crust are similar to the ripples that spread across the surface of a pond after a rock splashes into the still water. Seismographs are sensitive instruments that record the vibrations of passing seismic waves.
Fun with the Impossible Penrose Triangle I found this delightful animation today: The ball is traveling around a shape that can’t exist in our real world: the Penrose triangle. This illusion is the basis for some cool art, like Escher’s Waterfall. And I’m using it in my Math You Can Play books as a design on the back of my playing cards: Want to Play Around with the Penrose Triangle? Here’s a few links so you can try it for yourself: Penrose Lego by Erik Johansson (CC BY 2.0) Book Update I’ve sent the first two Math You Can Play books to a copy editor (she edits the text part), so my focus this month is on finishing the illustrations and downloadable game boards. If everything stays on schedule, both Counting & Number Bonds and Addition & Subtraction should be available by mid- to late-spring. Get monthly math tips and activity ideas, and be the first to hear about new books, revisions, and sales or other promotions. Like this: Like Loading...
The Language of Maps Kids Should Know Though in the age of iPhones and GPSs we seem to be losing paper maps, I still love exploring maps, and believe kids need to learn map skills, and develop their geography awareness. Because of this I have many activities on Kid World Citizen to help parents and teachers teach children about maps. Kids not only can learn to read them, but to recognize their components and build their own maps. I was recently asked for a list of vocabulary or concepts of maps kids should learn. Here are the geographic terms- and their definitions- that I think are important for kids to be able to identify. Want the materials for this lesson? Buy a full lesson plan about Map Vocabulary at the Kid World Citizen store at Teachers Pay Teachers! The Map Vocabulary Lesson Plan features three activities that help students develop a strong foundation in the geographic terminology associated with maps.

Photographer Creates Stunning Symmetric Images with Light and Reflection | Bibbi Abruzzini All Photographs (c) Ferdinand Choffray, Courtesy of Ferdinand Choffray Could symmetrical composition be part of defining beauty? Symmetry makes it attractive. The shots of Brussels-based photographer Ferdinand Choffray will show you the timeless power of symmetrical composition. But how did he get started? Armed with a keen eye and irrepressible curiosity, this photographer turned 'urban explorer' is an expert in capturing pictures from rooftops, construction sites, lost places and abandoned buildings. "I like the way photography forces me to go out, it constantly makes me explore new places and be in contact with new people. Natural light is an important tool available to photographers, and fortunately it is free. "I photograph the same places multiple times. With his images this young photographer wants to show us that we can enjoy great views by directing our eyes towards the right spot. « I'm showing the unusual of places you can see everyday.
Where is Earth's water? The USGS Water Science School "Water, Water, Everywhere...."You've heard the phrase, and for water, it really is true. Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground. Below are two representations of where Earth's water resides. The globe image represents how much actual water exists, compared to the total size of the Earth. Distribution of Earth's Water In the first bar, notice how only 2.5% of Earth's water is freshwater - the amount needed for life to survive. View a larger version of this image and learn more.
