The Teacher Who Believes Math Equals Love : NPR Ed What makes a great teacher great? That's the question at the heart of 50 Great Teachers, from the NPR Ed Team. For her trigonometry class, Sarah Hagan (center) uses everything but the kitchen sink: a flower pot, garbage basket, rolls of tape, rubber balls, even loose spaghetti. Elissa Nadworny/NPR hide caption toggle caption Elissa Nadworny/NPR For her trigonometry class, Sarah Hagan (center) uses everything but the kitchen sink: a flower pot, garbage basket, rolls of tape, rubber balls, even loose spaghetti. Elissa Nadworny/NPR Sarah Hagan has a passion for math, and the pi-shaped pendant to prove it. The 25-year-old teaches at Drumright High School in Drumright, Okla. There are no stoplights, no movie theater and no bowling alley anymore. That makes it hard enough to attract good teachers, says Judd Matthes, Hagan's principal. "We don't pay a lot in Oklahoma for beginning teachers," he says, laughing from behind his desk in the school's basement. Sarah Hagan's answer: Yes, spaghetti.

Shapes tessellate if they fit together without leaving any spaces Like these: A square A rectangle isosceles

Exploring Geometry by Coding With @gosphero & @tickleapp In this article I would like to dissect the Math curriculum here in Ontario and focus on the process of mathematics. From the Ontario curriculum document: Problem Solving Problem solving is central to learning mathematics. By learning to solve problems and by learning through problem solving, students are given numerous opportunities to connect mathematical ideas and to develop conceptual understanding. Computational Strategies: They may need to apply the written procedures (or algorithms) for addition, subtraction, multiplication, or division or use technology for computation. Representing In elementary school mathematics, students represent mathematical ideas and relationships and model situations using concrete materials, pictures, diagrams, graphs, tables, numbers, words, and symbols. Communicating Communication is the process of expressing mathematical ideas and understanding orally, visually, and in writing, using numbers, symbols, pictures, graphs, diagrams, and words.

21 GIFs That Explain Mathematical Concepts “Let's face it; by and large math is not easy, but that's what makes it so rewarding when you conquer a problem, and reach new heights of understanding.” Danica McKellar As we usher in the start of a new school year, it’s time to hit the ground running in your classes! Math can be pretty tough, but since it is the language in which scientists interpret the Universe, there’s really no getting around learning it.

Shape Worksheets I organized these shape worksheets by grade level, as sometimes, if a child is motoring ahead, or lagging behind in a certain area, the last thing you as a parent wants to do is spend time scouring a website looking for the next level worksheet. If you are currently working on a specific grade level rather than this specific topic - please vist the geometry worksheets zone. Geometry is the study of shapes, so this section cannot be overlooked by any student. Many times, because of the structure of the elementary educations, a second grader has lost much of their knowledge of shape recognition. Don't let this happen to your kids. If you have any suggestions on how to make this site better for you and other readers, please don't hesitate to contact me. Return from these shape worksheets to our Geometry Worksheets hub.

Maths Everywhere Using Bitstrips To Create Interactive Comic Math Problems | Roflections Recently, I have been working with staff on integrating Bitstrips For Schools into their classrooms. Most of the ideas that were discussed involved using Bitstrips for literacy, social studies, history, health, and even science. However, math never really entered the discussion. So I searched the shared math activities that were posted by other teachers on the Bitstrips For Schools website and only found a total of eight activities. All of these activities consisted of instructions for students to create their own comics. Here is an example of a shared activity that was posted: Grades: 6-8, Subjects: Mathematics Create a 3 panel strip to explain how to calculate the area of a triangle and/or parallelogram. This particular application of Bitstrips is more of an assignment which focuses on students creating a product based on a set task. The following is a primary algebra word problem: Mr. I took this word problem and turned it into the comic below: Like this: Like Loading...

5 Best Apps for Math and Counting | Technology In Early Childhood As a follow up to my post about writing apps (which you can click here to see) I thought I’d share some of the math and counting apps we’ve discovered. Again, it’s been challenging to find the few jewels among the plain old rocks. I really hadn’t realized how many apps were out there, nor how terrible some of them could be! The ones I list below (in no particular order) are the ones that I like because of their educational value, and that kids like for their entertainment value. Each of these apps (except for Count Sort Match) offers a free “lite” version and a full price version. Click on the title or the picture to see the app in the app store. Count Sort Match This app showed up on Free App Friday last week. ) My students don’t find the “Sort” game particularly compelling, but they do like the “Match” game. Hungry Fish This app is particularly popular with the boys. Math is Fun Ages 4-5 I review this app here, and it’s still a favorite among my students. Butterfly Math Park Math
