Truths & Lies Activity

Super excited to share this new activity with you guys. It was inspired by Sarah over at mathequalslove when we discussed some common activities that could be structured around all courses. One of those awesome ideas was the game Truths & Lies which is amazing!! 

I originally came across this idea as an icebreaker that you do on the first day with your students so everyone can get to know each other and get a few laughs.

1) Allie & I were almost licked by a giraffe 
2) I've been ziplining in the mountains
3) I won $1000 on a lottery ticket

Can you guess which one is the lie? 

Wait for it!

Wait for it!

Wait for it!

Eventually I'll tell you...

I promise I will...

Don't cheat...

Which one do you think was the lie???

Our first trip to the zoo was amazing! Thanks to an awesome friend 
who let us come visit over the summer and took us to the zoo. 

Wish I had gotten someone to take the pictures but it was a last minute decision. You know your an exhausted momma and teacher when you would rather take a nap during free time than go zip lining or ride go carts. HAHAHA!! Luckily when I woke up there was still plenty of play time left. This was truly an awesome experience and I hope to do again in the future.

Well I guess you now know I haven't hit it big with the lottery. I'm smart enough to use my money for something that is a sure thing... like new teacher clothes!!

So back to the activity...

Later I came across the idea while looking at twitter or a blog about how someone used this idea in the classroom (honestly, I can’t even remember where – too many great resources). I then decided to use it in my classroom with my geometry unit and congruence shortcuts where students in groups had to create 2 correct examples and 1 wrong example. Then all the other groups had to try to figure out which example was incorrect. It actually worked really great and got them talking. 

After talking with Sarah about some other cool ideas this truths & lies kept coming back into my mind and I really wanted to make another card sort type game but with a little change. The activity below is what I have come up with so far. I have made one for my math 2 class on the sum of the angles in a triangle and one for my math 1 class on systems of equations using elimination. Here is a picture from class. 

I'm also thinking it might be cool to laminate some larger ones and let kids make their own and switch among groups. If I try it out I'll let you know how it goes!

  1. How did the math 2 one go? Seems like a really cool idea!

    1. It went really well. They liked it because it was something different. I'll definitely be doing it again with a different topic :)

    2. Okay great! I will be a first year teacher next year teaching Math 2, Pre-Calculus, and AP Calculus AB so I have been trying to find fun ideas that are more engaging!

  2. Wow that's soooo Exciting!!! Definitely keep searching different blogs looking for awesome ideas. I'm sure if you found my blog you probably already know all about the #MTBOS. But if not please message me back so I can share lots of tips on how to find other cool ideas. And how being on twitter is the best thing you could ever do your your career and first year as a teacher. I have tons of great resources saved in my virtual filing cabinet tab with the google doc that is labeled important links & resources by topic. Also I'll be adding another google doc soon with links to my card sorts and activities that I have already made this year. Hoping to blog about them soon.
