We spend 50% more hours in school than Finland. They get 15 mins of recess every hour. They have NO standardized tests except for PISA in HS and they outperform us every time. When we can’t give students more recess, physical activity & Arts then we don’t understand education.

If you’re afraid that books might change someone’s thinking, you’re not afraid of books, you’re afraid of thinking.

Seduction and romance are found being lost in the wilderness of mathematics. Schools have no time or patience for such dilly dallying. @ChasingMath

Our #1 goal this quad in #MTH1W is to "Improve the Student Learning Experience in Math."

This was a grade 9 math student's thoughts after 2 hours in a #thinkingclassroom. We're on the right track! @pgliljedahl @Desmos #mtbos #iteachmath

I keep thinking about this Stokely Carmichael quote: “If a white man wants to lynch me, that's his problem. If he's got the power to lynch me, that's my problem. Racism is not a question of attitude; it's a question of power.”

I cannot emphasize enough the importance of having people in your life who, when you're rejected/passed over for an important-feeling thing, reply without hesitation, "wow, how sad for them that they got it so wrong" and mean it.

[Howie Hua @howie_hua]

Two phrases I've been saying frequently in class:
1. It's okay if you are wrong. I just want to know what you're thinking.
2. Remember, we're on the same team. I'm here to help.

What do you notice here? What patterns do you see? What might the fifth design look like? What about the tenth?

Making links with quadratics. A short vid showing how to use the quadratic model. It is a great way to get pupils connecting Maths. For Y9/10/11/12 I will post a blank template.@WRMathsSec @mathsjem @mrshawthorne7

[Patrick Honner @MrHonner]

I've known many math teachers who bragged about how hard their tests were. As sad as this is, even sadder was the artless way they did it: by making tests unreasonably long, by requiring absurd computations, or by testing out of scope of what was taught.

Rainy afternoons = playing with maths. This is the 13 times tables plotted on a 180 point circle. Mathematics can be so beautiful #mathart #mathisbeautiful #mathsart #beautyinmaths #multiplication

Mathematics is everywhere. This short movie by @cristobalvila is a beautiful illustration of numbers, geometry and nature. Truly inspirational.

I just received what may be the kindest and most gentle comment anyone has ever given in a peer review. I am framing this.

[Kevin Ashworth @SLOlifeKevin]

If you're not following @howie_hua and you teach math, you are missing out. The end of this video killed me. Estimating for the decimal point rather than relying on "counting" - how did I not ever learn this!!
