Rick Barlow's tweet caught my eye not because of what the student had written on the board but because of the poster hanging above the dry erase board. I think this poster belongs in every math classroom. This is definitely on my list of posters to create for my classroom for next year.

Greta Bergman recently published a beautiful blog post about her approach to introducing students to solving systems of equations by substitution. I love how she approaches it from a task that students should feel comfortable with and slowly moves students toward the way problems are typically approached. I think we can all learn something by checking out this post!

Danitte Kozai's recent tweet about challenging her students to do discover formulas in trig instead of simply giving them the formulas has me want to restructure my entire trig class. I only get to teach trig every other year, so I guess I should wait a bit before tackling that...

In the most recent issue of Monday Must Reads, I featured a visual representation for solving equations. I wondered how it might work with equations that have variables on both sides. Yah Lee answered my question with a visual model that does just that! I've played around with it, and I like it. The only thing I can't figure out how to do now is illustrate an equation that involves subtraction one one side of the equal sign and addition on the other side.

I was first introduced to Conway's Rational Tangles problem through a summer immersion program hosted by the Tulsa Math Teachers' Circle. Amie Albrecht shared in a recent blog post how to use the questions "What do you notice?" and "What do you wonder?" to motivate the activity. I think this approach is simply brilliant.

Katrina Newell blogged about her interactive notebook pages for angles formed by secants and tangents. I love how she encouraged her special students to use two small pieces of paper to better visualize the arcs and angles. I think this is a strategy that all students could benefit from!

Maths teachers in the UK have been honouring the late Malcolm Swan's contributions to maths education by using his resources in their classrooms on #malcolmswanday. Pip Mathematics shared a great Swan task that I look forward to incorporating when my Algebra 1 students tackle evaluating expressions in the fall.

Theressa Engel shared students' results to a problem-solving task I would love to try out with my own students: create the longest chain possible from a single sheet of paper. I'm thinking this would make a great first week of school activity!

Sam Shah recently shared a brilliant introduction to the unit circle in trigonometry using every shape but a circle!

Susan Russo took the traditional spaghetti activity for graphing sine and cosine curves a set farther by hanging them side-by-side to create a beautifully long graph.

Andrew Jensen shared a brilliant geometry task regarding wasted packaging space.

Until next time, keep sharing!

I LOVE LOVE these posts!! There are so many great posts on twitter and I feel overwhelmed sometimes trying to read them all so I appreciate you picking out some of your favorites so I can see stuff I miss!

ReplyDeleteSarah let me just say again how much I appreciate you and your work in posting for others. We all encounter these wonderful trinkets of awesomeness but rarely do we take the time to "give back" the way that you do. I am thoroughly inspired with every visit to your site. I try to pay it forward to my students and the other teachers in my district.

ReplyDeleteBless you!

Oh... my whole purpose for commenting was to say that I have gotten about 5 different pearls of inspiration for a Pre-Algebra summer course I am creating from this one post!

Thank you , thank you! Madelyne
