# Resources for Teaching Integers

I was recently contacted about whether or not I had any resources for teaching about Integers.  Of course, my answer was a resounding, “yes!”  But I was actually a little embarrassed when I had to admit to the person that I had never taken the time to organize them all into one easy-to-find place on the Internet.  So, that’s what this post is all about.  I hope that you enjoy the resources that I’ve collected for teaching integers.

Card Games

• Zero Sum Card Game – This is a card game in which students need to collect cards in order to reach the sum closest to zero.

Integer Bingo

• Bingo Master Template – This is an easy to use Bingo Master Template in which all you have to do is enter the clues and the answers.  The only limitation I’ve found is that it only prints 25 cards.  So, if you have more than 25 students in your class, you’re going to have a problem.
• EDU Bakery Bingo Cards – Here is a Bingo game that is ready to be printed out.  However, if you want to be able to edit the cards from what is on the website, you’ll have to pay the fee (except that there does appear to be a trial version available).
• Commercialized Bingo Game – This wouldn’t be my first choice for a Bingo game, but I can understand why someone would want to just buy the Bingo game since you wouldn’t have to take the time to print out the Bingo cards and the game probably would be reusable well into the future.

Integer Relay Races

I’ve used the files below in the past as ‘relay races’ in class.  You simply cut the sheets into strips and then have the students compete against each other.  Most students really seem to enjoy this!

Other Games and Activities

• Operation Integers – Maria Andersen has this ‘Operation Integers’ game over on her website in which seems to be a spin on a “target number” kind of game.
• Integer 500 – This is an integer game that involves putting a spinner together and things like that and seems like it would be pretty cool if you ever decide to try it (I haven’t).
• Integer Football – Apparently Integer Football is a popular integer game these days.  I haven’t tried this one, either.

Puzzles and Worksheets

• Math OPS Worksheets – MathOPS has some free puzzles available that can be printed out where the answer to every puzzle is the name of a “Famous Old Guy” in history.
• Integer Crossword Puzzle from NASA – I love taking advantage of all of the ‘Space Math’ resources over on the NASA website and this is just one of them that just happens to involve integer operations.

# Teaching Signed Numbers with Zombies, Ghostbusters, and Night Vision Goggles

Here are three new application problems that I came up with while teaching signed numbers this morning.  Remember, I came up with these on the spot, during class.  So, just imagine that the entire class is paying attention to each of these problems as I am writing them, trying to figure out what is going to happen next to Clyde in each of the problems.  I hope you enjoy these!

1.  Clyde was walking down the street and he lost 1/3 of his vodka.  A little later down the street Clyde encountered a zombie who wanted to steal another 2/5 of his vodka.  The zombie agreed not to kill him if he told him the total loss that he incurred, as a signed number.

2.  Clyde was running another scam where he collected \$6.20 from people to buy an invisible potion of life.  The local ghostbuster caught wind of this scam and blackmailed Clyde with a \$3.30 charge.  How much money does Clyde still have from this scam?

3.  Clyde was in debt \$12 to the local spy shop for some new night vision goggles that he needed to monitor paranormal activity coming out of the bottom of his shoes.  When Clyde informed the spy shop that they forgot to include the complimentary antenna that comes with his goggles, they subtracted \$4 off of his debt.  How much does Clyde still owe, as a signed number?

# Math Games for Integers, Multiplication, and Combining Like Terms

I have some slightly under-prepared students semester, so I suggested to them that they should try to work on their basic skills outside of class.  However, this requires me to provide some recommended resources to them, and these are what I have discovered:

Multiplication

• Tetris-style game for multiplication facts.
• Fun Multiplication Game that can be played with up to 4 people from around the world.
• For those who just want the traditional worksheets to practice with.

Combining Like Terms

• This like terms game requires you to match the center term with its the appropriate like term.
• Matching Game – Identify the matching terms in two columns.
• Distributive property, combining like terms, evaluating expressions, solving equations.
Integers and Order of Operations
• Pac Man-style game for Order of Operations.
• Circle 0 Puzzle – adding positive and negative integers to sum to zero.
• Circle 3 Puzzle – adding positive and negative integers to sum to three.
• Circle 21 Puzzle – adding positive and negative integers to sum to twenty-one.
• Circle 99 Puzzle – adding positive and negative integers to sum to ninety-nine.
