@carlblong.bsky.socialIn #MathsToday, 11th grade pre-calc Ss invented the Law of Cosines (and realized its usefulness).
Started w/ right triangle, changed it up. Derivation took a while, but w/ a _little_ guidance, every group found the formula!
Tonight, practice.
Next class, ambiguous case!
@pwharris.bsky.socialNice proportional reasoning Shawn! Cross multiply and divide would miss all of that lovely thinking. Well done!

@carlblong.bsky.socialIn #MathsToday, introduced composite functions to #Alg2.
Started with Collatz Conjecture, then these 3 prompts. Ss worked in groups for each, leading to full-class sharing/discussions.
Keeping it grounded at first, with units in mind. e.g. "Are you adding to the mileage, or to the money?"
