A Scavenger Hunt in Your Seat (and a FREEBIE!)



I recently have been trying something new in my classroom - scavenger hunts that can be accomplished by each student in their seat.  No moving around the classroom...sometimes movement is good, but sometimes you just need students to do an activity where they stay in their seats :)

In this activity (sometimes called a circuit - thank you to Virge Cornelius for this idea), students are given a number of problems to do.  They start in the upper left hand corner with problem #1.  They work to complete problem number one.  After they have figured out the solution to problem #1, they look for the answer to that problem somewhere else on the page.  This becomes problem number two.


Students seem to enjoy these activities as they are self-checking.

Would you like to try this activity with your geometry class?  

You can download it for FREE from my TPT store here...

Playing Bingo in a 1:1 Math Class


There are days when a fun activity is necessary - kids need to practice specific skills, and they need a break from lecturing and practice worksheets.

My students love playing Bingo!  But, I don't like all the time that has to be spent making the bingo cards (it takes students forever to make their own) - or if I make them, it takes forever to make the cards and then laminate them for future use.

Lucky for me, one of my colleagues introduced me to the website Bingo Baker.


This website allows you to enter words and images into a bingo card. [Bingo Baker is freemium tool - it is free to use up to a certain point and then costs $14.95 for a lifetime membership - well worth it in my opinion!]

Here is the beginning of my Antiderivative Bingo Game.


Notice that I was able to add a graphic to the center space easily - I just dragged and dropped from my computer.  If you want to add something that is easily typed like cos x or 0, you just type it right into the square.  Unfortunately, Bingo Baker doesn't seem to have an equation editor.  However, you can get around this if you have an equation editor that you can save your equations as pictures.  Then you can drag and drop those into your card.

Now to the best part!

Bingo Baker will automatically generate different bingo cards for you!  You can give the class a link to follow and each student will get a different bingo card right on their device.

This is a link to see the screen students would get if they were going to play my St. Patrick's Day Calculus Bingo Game...St. Patrick's Day Calculus Bingo Card

As you can see, if students push generate card, they will get their own card pulled up right on their screen.

Then, I project the questions on the board.  For example, here is a first question for my St. Patrick's Game.


Then all a student has to do is touch the screen where they find the answer to this question.

Calculus Optimization Project - Popcorn Box




This is a great project to do on the day before Thanksgiving Break.  It works anytime, but it is really nice to do on a day when you need to keep the students' minds on math.

Materials Needed:

construction paper
scissors
rulers
tape
calculator
big bag of popcorn

I begin by having this on my board when students enter the classroom.


Students immediately want to know "what's that for" and "are we having a quiz?"  (Eye roll!)  But at least they are paying attention to their surroundings and I am generating interest in the day's lesson.

I have students choose a partner and then sign their name next to one of the (what will turn out to be) measurements on the board.

I explain to the students that we are going to make boxes out of their piece of construction paper.  They cut squares of equal size out of each corner of their sheet of construction paper.  Each group uses the measurement next to their name on the board in the front of the room.


After students cut the paper, they fold up the sides of the box and tape them in place.

Once their box is made, each group calculates the volume of their box.

I have each group write the volume that they calculated next to their names on the board.

Once all of the groups have written their volumes on the board, we look to see which measurements will give the maximum volume of the box.

Then we figure out, using algebra and the calculator, exactly where and what the maximum will be.  The construction paper that we use is 9 inches x 12 inches.  Students use these measurements to come up with a formula that will represent the volume of a box that can be formed if squares with sides of length x are cut out of the corners of the construction paper.  This graph is generated.

We talk about the graph and realize that for this particular situation, we only want to use the part of the graph between x = 0 and x = 4.5.  [squares larger than 4.5 cannot be cut out of the paper].

Of course, none of this actually involved any calculus.  I use this entire activity as an introduction to the idea that we can all start with a given constraint - in this case the piece of 9 x 12 construction paper - and generate different solutions to the problem - in this case make a box.  Which one is best? 

Then we talk about different types of optimization problem situations - I specifically bring up whether pop is in the most cost efficient container.  I actually have a coke "can" in the shape of a (sort of) sphere that Coke put out several years ago for Christmas.  Or, Dr. Pepper, made a special edition "can" in the shape of a football several years ago for the beginning of the football season.

After our discussion and calculator work, students get to fill their box with popcorn and eat!

Another Way to Use Scavenger Hunts





My class loves a good scavenger hunt...you know the kind - you post problems all over the room - students start anywhere and work a problem, then find that answer posted somewhere in the room.  They continue to work problems until the end up back where they started.

But sometimes, you have a class you just don't want to let out of their seats.  Or maybe you want to hold everyone accountable for the work.

Fun First Day Math Activity - Algebra Review Using Clue





Last year I did a breakout game with my calculus class for beginning of the year review.  I will probably do that again this year to help them review some things for PreCalculus.  You can read about that here: Making a Breakout Game

But, this year I decided that I wanted to try something with my Geometry class too.

I have to thank Stephanie Howell for this idea.  I heard about it on the podcast Hacking Engagement - you can hear it too - Hacking Engagement Clue Game

So, here are the steps I went through to make this game.

Using Uno as an Intro to Teaching Proofs



I recently came across this idea on Pinterest, and I LOVE it.  I am sorry, I don't know who the original credit goes to for coming up with this idea is...if you can claim it - let me know :)

As we all know, getting students to understand the whole IDEA of a proof is difficult.  Then throw in theorems, postulates, reasons, statements UGH...it's too much.  The reason I love using Uno to start teaching proof is that you begin the lesson with something students are familiar with - many have played Uno before.
