Math Journal Sundays Ahhhhh ... Sunday morning. All is good. I've got a quick little foldable to share with you today from our math journals. We're just finishing up our Measurement unit (we've covered measuring length, metric conversions and perimeter and area of rectangles, triangles and parallelograms). Our test is on Monday, so we spent Thursday and Friday in review. We made a 4-corner foldable to review the formulas for the area and perimeter of the different shapes we learned. That's about it ... Happy Sunday!!! Brain Teasers Sliding Triangle The triangle at left lies on a flat surface and is pushed at the top vertex. The length of the congruent sides does not change, but the angle between the two congruent sides will increase, and the base will stretch. What is the maximum area achieved during this process? This brainteaser was written by Derrick Niederman. Solution: 200 square units; 32 units. For the first part of the question, the maximum area occurs when the angle between the sides is a right angle. For a more advanced trigonometry solution, remember that the area of a triangle can be calculated by taking half the product of two sides and the sine of the angle between those sides. For the second part of the question, note that if you bisect the original triangle, divide it into two right triangles, and rearrange the pieces, you can form a new triangle with exactly the same area. Again using a trig solution, A=(1/2)absinθ, where a and b are the side lengths.

Canva for Education - Lesson Plans Incorporating Visuals Across the Curriculum Canva is a nice tool for designing infographics, collages, flyers, and slides in your web browser or on your iPad. I've been a fan of the service since it launched. In fact, I like it so much that I became an unpaid advisor to them when they started thinking about developing resources specifically for teachers. The new Canva for Education site features eighteen lesson plans written by Vicki Davis, Steven Anderson, Terri Eichholz, and Paul Hamilton. The lesson plans include things like Paul's making historical infographics in which students summarize and visually represent the connections between historical events and their causes. Check out the Canva for Education page to find all of the lesson plans and tutorials on how to use Canva.

Johnnie's Math Page - Fun Math for Kids and their Teachers Johnnie's Math Page is the site to find fun math for kids, math games, and even a little math homework help. Interactive math activities from across the web have been organized by topic to make math learning enjoyable and interesting. These activities have been chosen to represent the range of math learned from kindergarten to middle school. I have put together resources for middle school math. In the middle school math section you will find fantastic models for all kinds of algebra- from linear equations to quadratics. For parents and teachers, you will find math lessons and free math worksheets as well as links to other math teaching resources. For those who like a challenge, you will find free math games in the math puzzles section. Contact Johnnie

Chart students’ growth with digital badges By Kristin Fontichiaro and Angela Elkordy 2/26/2015 Topics: Gamification, Assessment Remember turning in your grades at the end of the school year? Did Zack’s B in geometry tell you enough about his mastery of the Pythagorean theorem or the area of a rectangle? K-12 educators, particularly at the secondary level, are considering these questions and asking if today’s scoring metrics are able to provide a robust picture of who our students are and what they can do. Educators are hopeful that a flexible assessment model called digital badging is a way to bridge these gaps and describe student attributes that are currently left unacknowledged. What is digital badging? Today, we learn everywhere: in formal classrooms and informal basement workshops; in less-structured environments, such as makerspaces and libraries; and in more-structured contexts, such as religious institutions and dojos. Badges unpacked Digital badges are created in online badging systems. Learning objectives.
