@approx_normal @jamestanton illustrates a powerful approach to problem-solving: if you want something to be even, then make it even! If you want it to be a perfect square, then make it a perfect square! And if you want an even perfect square, then life is golden!

@approx_normal @jamestanton has a brilliant series of lessons on quadratics here: https://t.co/Bodu836ENB you could easily adapt the drawings he makes to a hands-on experience with algebra tiles. Check out unit 2!

How do you see these points moving ?
Ben Sparks @SparksMaths started a great talk last week for #latemaths with this simple animation. People see different things. What do *you* see ?

We made this cool spinner to help my geometry students visualize rotations. Then a student asked, “Is this brad real gold!?” 😂 #teach180 #iteachmath #MTBoS

@TPMS_AP @LoiedermanPrinc @LMSMagnetAP It was a blessing for sure!

San Francisco detracked math. The results: # of students repeating algebra fell among all ethnic and racial groups,fewer are receiving D's and F's in Algebra 1. 1/3 more students=ready for calculus, and that pool is more diverse. https://t.co/yISyn0haX5 @nhannahjones

@mrchasemath @wrose31 @jamestanton This is helpful. Can you describe the effect of this transformation geometrically?

[James Key @iheartgeo]

@wrose31 @mrchasemath @jamestanton You appear to be saying that linear transformations preserve incidence but may distort distances. What kind of transformation does the opposite?

@Nano82 My thoughts on integer rules here: https://t.co/32G1vRXU8G. Let me know what you think!

[James Key @iheartgeo]

@Nano82 How will students relate the sign rules to the distributive property using this model?
