@howie_hua Yes, making 10s is a very important early math strategy however turning ‘10 frames with counters’ into a worksheet is very confusing and silly in my opinion.

How would you find the 100th term of the sequence 3, 7, 11, 15, 19,...?

One of my students showed me a strategy I will never forget.

[Howie Hua @howie_hua]

Might be embarrassing to say but I didn't realize exponent and power weren't the same thing until around 5 years ago.

[Joanne Simmons @gnitnuoc]

@howie_hua For those asking whether this is mathematically important or just semantics, I’d say it’s ‘ Instructionally Important’. Emphasizing the result as the power interrupts the common misconception that we multiply 2x3 to find the ‘answer’. Language matters in math instruction.

[Howie Hua @howie_hua]

Can you visualize fraction division on the number line? If not, give me around 90 seconds to explain it.

It is mathematically impossible to perfectly tune a piano. Here's why.

Really great blog!! Important for intermediate teachers to know! @SWLiteracy

@SciInTheMaking When instruction is guided by cognitive science, high-impact strategies, and the belief that every student is capable, we give them a shot at reaching their pinnacle of success. Thank you @SciInTheMaking this is why we fight for evidence-based instruction #ScienceofLearning

Teaching area formulas as how the shape is related to a rectangle helps build conceptual understanding.

Here's how to derive the area formulas of a parallelogram, triangle, trapezoid, kite, regular hexagon, and even a circle from the area formula of a rectangle:

Happy π Day!!

The meaning of π using pizzas.

Cutting and laying the crust of a pizza across four others with the same radius, youl'll find that the crust spans a little more than 3 pizzas or ~3.14

God Damn, @ArleneDickinson is on a roll, much respect for that woman. Sure hope she considers running for public office, Canada needs more Arlene, less @kevinolearytv.

The smaller circle rolls inside the bigger circle, while the four points actually just move in a straight line. 😲 [https://t.co/L8AsEcy6j8]
