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

[Lizz Ellis @mathwizlizz]

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

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

[Lizz Ellis @mathwizlizz]

@AnkerMath @MissDavisSCSD found it!

[Lizz Ellis @mathwizlizz]

@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!

[Lizz Ellis @mathwizlizz]

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

[Lizz Ellis @mathwizlizz]

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:

[Lizz Ellis @mathwizlizz]

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

[Lizz Ellis @mathwizlizz]

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! ✨

[Teays Valley Schools @TV_Vikes]

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

[Lizz Ellis @mathwizlizz]

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

[Lizz Ellis @mathwizlizz]

@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!

[Lizz Ellis @mathwizlizz]

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!

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!

@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!
