Played my favorite review game, Attack, today that I found on Pinterest a year ago, but have now adapted it to make it my own. See thread for rules!

i decorated my graduation cap

@mr_guindon Congratulations!!! I didn’t know you got in! Can’t wait to hear about it!

Still humbled and honored to see my name on this list. Can’t wait for July!

End of year project for Geometry. Students can only use construction tools (digital or traditionally). Columbus people will understand #savedthecrew

@AnkerMath @MissDavisSCSD found it!

Chalked a number line from 57" to 74". Students stood on their height line. I took a class photo to show how clustered data affects the way a boxplot looks! #mtbos #statschat

@MissDavisSCSD I had my students line up on a number line based on their heights, took a picture then sketched a box and whisker plot over them and asked them what they see, notice and wonder. I saw something like this on twitter, but can’t remember who posted it to credit them!

I'm teaching #BoxAndWhisker plots next week to help my #algebra1 students prepare for their #EOC. Any suggestions from the #MTBOS community? #iteachmath #alg1chat #testprep

@MrsCookKHS I love that! We’re watching hidden figures right after testing, so that would be a great transition!

What are your favorite post-state testing activities/lessons, specifically for Algebra 1 & Geometry? Here are some not-so-thought out ideas I had, but would love to know more:

@harpgirl555 Oooh...I like that! I’ve thought about doing a “copy my construction” activity, but forgot about it! Love it!

I’ve also thought about doing a choice board with some of the less involved ideas listed. Wondering if anyone has had experience with that...are making rubrics (and then grading) for each choice a nightmare?!

Gym is decorated, t-shirts loaded in my car and everything is ready to be decorated at Franklin Park Conservatory. It’s Prom Day, Vikings! ✨

It's prom day! Have a safe and enjoyable night, Viking Nation!

@arzzax No, the second one they used 415 as the initial value and used growth instead of decay to work backwards, which makes sense to me but doesn’t give you the same answer

@mathwizlizz I'm assuming the second one is meant to be 415=a(1+.12)^6 as opposed to your 415=a(1-.12)^6? They've assumed it's exp growth not decay, so when solving for a it will reduce 415 instead of increasing it.

I had an exponential decay problem on my last test where Ss had to solve for initial value. I set it up as 415=a(1-.12)^6. A student set it up as 415(1+.12)^6. Why doesn’t this give you the same answer? #mtbos #iteachmath

@mathgeek76 Mowing your lawn using safety scissors...unnecessarily tedious when lawn mowers exist

it always makes me a feel a little 🤢🤢🤢 when I see curriculum give Ss a bunch of data and ask them to graph displays by hand and “do not use a calculator.” How would you complete this sentence: Asking students to graph data by hand is like... #mtbos #iteachmath #statschat

@DawnRecentio @KristieDonavan @cmt215il No, I used a Desmos activity! I believe it’s called something about Avi and Benita and it’s the first one in the exponential bundle. Although, that would be a good idea!

@mathwizlizz @KristieDonavan @cmt215il Thanks so much!!! Is this how you introduce the topic?

Exponential functions are BY FAR my favorite unit. In one day, we have talked about college loan interest rates, the opioid and orphan epidemic in Ohio and the use of cell phones by elementary age students, all on real data. My kids are LOVING it and learning that math is power!

@DawnRecentio @KristieDonavan @cmt215il Here are the articles that we used: bit.ly/2uA7L5G bit.ly/2TFz1JP bit.ly/2FJG4gW For the college interest rates, I had kids look up how much the college they want to go to costs, multiply by 4 and use that as their initial amount!

@KristieDonavan @cmt215il @mathwizlizz Me too. I’ll be starting exponential the end of next week.

@MrsSasser Here are the articles that we used: bit.ly/2uA7L5G bit.ly/2TFz1JP bit.ly/2FJG4gW For the college interest rates, I had kids look up how much the college they want to go to costs, multiply by 4 and use that as their initial amount!

@mathwizlizz Have any resources to share?? It’s coming up for us and I would love to make it more relevant for my students!

@scitecheducator We did a textbook example of this, but not sure if the date is real. That would be interesting to find an article on it!

@mathwizlizz Don't forget half life of drugs in your system. I like the number play and real life feel of this unit!
