Can you Solve the TedEd Temple Riddle?

TedEd did it again. They produced another fantastic riddle that my students love. I first blogged about the Bridge Problem here and then about Einstein Problem here. There are a few more riddles that have been produced, such as the Prisoner Hat Riddle and the Green-eyed logic puzzle. And their latest does not disappoint...The Temple Riddle.

Each riddle provides a great story line that hooks the students. The animation is fun and the voice is great. Each one tells a tale that is seemingly impossible to solve, and then you can pause the video so that the students can attempt to find a solution.

Today, my students were at first very stumped (as was I!) with the Temple Riddle. We worked on it for at least 15 minutes, everyone coming up with different ideas and several students coming to the board. A student finally came up with the solution, but another student wasn't sold. What's great is that when you unpause the video, it explains the solution fully, so that anyone who was confused will no longer be. They are all awesome, and this one is the type of problem that my students crave.

Here are the five of them all in one place if you would like to share them with your students. I recommend spacing them out so that they look forward to them--because they will. More are being made, so stay tuned!

My Log B(log)

I'm starting logs in my Algebra 2 Honors class upon return from winter break. There's been a few great posts that I've found on these blogs from Wendy Menard, Julie Reulbach, and Kate Nowak. They are all fantastic, and I've used much of their ideas in my documents...so here's notes, links, etc. for exponentials and logarithms, that could go with any text, though I use Larson Algebra 2 and Trigonometry, 9e. Keep in mind that I teach in 90 minute blocks. Each note packet is for a day, but I haven't used them yet and so some could go over. These are linked to my dropbox, so you will need an account to open them.

--First, I am using this Desmos intro to exponential growth and decay. This is a play on the doubling pennies idea and the m&m's exponential decay problem along with graphs.

Then I will give out these Exponential Notes.

When I find the time, I am going to throw in these two videos:

-- a Ted Ed video on how many folds of paper can get you to the moon

-- a Mythbusters video on paper folding

On Day 2, I will give them these Intro to Logs Notes.
--includes the Need for Logs (click on Wendy's and Julie's link, above)

--includes the fun puzzle from Kate (click on her link, above)


My plan is to use this Kahoot! as a good brain break that day.

On Day 3, I will hand out Laws of Logs Notes (nice way for students to figure out the laws in groups, by Kate.) We have a week of immersion before these notes (and no class), thus the big review in the beginning.

On Day 4, they will get A Huge Review of Logs and Exponents (I haven't checked answers! The last half is a review sheet that I once found, but I don't know where to give the credits to. The latter is for them to do on their own, if they want to)

What did I miss? Please send anything my way :)
