Oops, I forgot: Building Sinusoids
Build the equation of a sinusoid that passes through the point (90, 2)
Sketch a graph of the sinusoid you build.
Oops, I forgot...
-The sinusoid needs to have an amplitude of 3
-The sinusoid must only have y-values that are positive
-The sinusoid must also pass through the point (0, 2)
-The phase shift is larger than one period length
Did a fun #OIFMath today with sinusoidal functions, tweaked from the original found at natbanting.com/oops-i-forgot

Round 3: roll a die, place the number in a square. Goal is to get as close to 2000 as possible though multiplication without going over. Wrinkle: two throwaway boxes, so you can opt out of two rolls. 6 rolls total.

A paper handout to record numbers provided by a die to get near a desired result
The activity:
Round 1: roll a die, place the number in a square. Add the numbers. Goal is to get as close to 800 without going over. 6 rolls total.
Round 2: roll a die, place the number in a square. Subtract the numbers. Goal is to get as close to 200 without going under. 6 rolls total.

Thanks for this, Dan! A colleague of mine adjusted the plans slightly to cut down the creation time (took about 6 hours for our printer to make this green one). Looking forward to extending the lives of these!

I agree and feel like itβs by design too. This came as news to us about a month ago, and it sounded like surprising news to our admin too. Too much fine print, not enough transparency.

Ss can opt out of their e-learning requirement, but we found out that schools arenβt funded for the courses they opt out of. Schools are then allocated a number of e-learning classes the Ts at that site must pick up, leading to fewer classes offered at their schools and higher class sizes π’

How has your first week of the semester been?
Three non-math related topics I know a lot about areβ¦..
One thing I'm looking forward to this semester is...
Draw a mathematician in this box.
I feel _____ about this class because...
Someone I met this week that I didn't know before is..
A question I have for the teacher is...
Write the largest mumber you can in this box.
I gave students the autobiography as well as a questionnaire (see below) at the end of the first week, after they experienced a few non-curricular tasks and got a sense of what the classroom structure was.
Build community, dig deeper about who is in your community, then start to grow together.

If you believe students donβt have math trauma, test that theory by having them write a mathematical autobiography. I learned so much about who they are and what they bring to the classroom. BTC as math therapy, merging the work of @themathguru.bsky.social and @pgliljedahl.bsky.social this semester
