Spend It All!

Here is another math activity that will have your students practicing subtraction of decimals, regrouping, and unit rates!  It's also quick and easy to make!

You will need index cards, scissors, glue and store ads.
Cut out items on sale from the store ad.
I tried to chose items that I know my students would be interested in.


Next, glue them onto index cards.  Try to glue them so that you will have room to write on a section of the index card.  Also, only glue one per card.


You have two options to choose from for this next part.  You can either use markers to write on the cards or you can print out the info and glue it onto the cards.  I chose the easier one. :D

Here is what I came up with!  Notice, on some of the cards students will have to determine unit rates.
Here are some more examples for you.


How do you play "Spend It All"?

Number of players:  2 to 4

Materials:  Paper, pencil and one set of "Spend It All" cards.

Directions:  Place cards face down on the center of the table.  Each player starts with $100.  Player 1 takes a card from the top of the stack.  This represents a purchase.  The card will state the number of items the player must buy.  The player will then subtract the amount from their $100.   Player 2 then repeats the same process.  Each player will have different cards (purchases) each time.  The player to "Spend It All" first is the winner!!!



As you can see, it is great practice for subtraction from zeroes and regrouping.
I would let each group have a calculator so they could check each other's work. This is great for immediate feedback and if the student knows he or she did the math correctly, their confidence level is raised!
Here are some closer looks at the cards.  Hopefully it will give you some ideas! :D





I truly hope this activity is helpful and of use to you! I think that it is good to have students work with something they see everyday outside of school, such as these ads. That way, they can actually realize that math IS important to learn and that they WILL use it in their daily life.

Practice Integers with a Deck of Cards!

First of all, I know first hand that buying materials for your classroom can get pricey and adds up to quite a bit by the end of the year.  This is why I try to look for ways to save money on items for my classroom.  I also try to look for items I can use in more than one way.

Now, onward to using a deck of cards for integers!

I found the best deal at Dollar Tree!  You get TWO decks of cards for $1!  Fifty cents a deck is a real bargain. Of course, if you can get them donated, that would be even better.



Here is what the package looks like if you happen to have a Dollar Tree near you.  If not, I'm sure you can find them at other types of dollar stores.


They are glossy and pretty durable.
I usually take out the Jokers, since I have no use for them.



This is how I use a deck of cards to have my students practice addition of integers.  My students call it Integer War and it is a game for two players.

First, I tell students that all face cards (King, Queen, Jack) have a value of 10.  All blacks are positive and all reds are negative.

For example, 6 of diamonds (red) has a value of (-6) and a Jack of spades (black) has a value of (+10).  I then instruct students to use addition to solve.

Step 1: Divide the entire deck of cards between two players.


Step 2: Both players take a card from the very top of their stack and place them down next to each other.  Be sure to tell you students that peeking is not allowed!  They MUST take the card from the top of the stack.  Now they have created an integer problem!  This one shows (+10) + (-8).
Step 3: The first student to shout out the answer takes both cards.  The coolest part is that they can use the symbols on the cards to create their "zero pairs" if they are still struggling solving it mentally!  Since face cards don't have symbols, you can have students take all face cards out for the first few times they play this game.  Then have them play the game with the face cards included as they are gradually building integer fluency.

Here are some more examples:

(+10) + (+7) = (+17)

(+10) + (-10) = 0


(-4) + (+10) = (+6)
(-10) + (+8) = (-2)
(-10) + (-10) = (-20)

It's that easy!

I think the colors really help students determine positive and negative values and understand when they have to add or subtract the values.


I usually have my students seated in groups of four. So what I do is have two students play against each other and the other two students use a calculator to check the answer.  That way they know who stated the correct answer first.  Then the pairs of students trade tasks.  It's a great way to build integer fluency and students end up discussing when answers are incorrect.  They teach each other!  How awesome it that?!

Take it to the next level!  After students understand directions and the goal of this game, change it up and have them subtract the integers.  I usually have them write down the problem when they use subtraction.  Eventually, I also have them practice multiplication of integers.

So you actually get THREE activities that will have your students practicing with integers using only one deck of cards!



WARNING!  When students are playing this game, you will hear them gradually get louder as they shout out the answer, because they want to win!  They get really excited.  Student engagement at it's finest!  :D

Here are some of the activities I have available at my Teachers Pay Teachers Store.

Integer Fluency Circles


Exponents with Integers


Christmas Tree Negatives and Positives - Mixed Computation with Integers This one is FREE!


I will be posting other ways I use decks of cards in my classroom at a later date.  Stay tuned!

Thanks for looking.  I hope this was helpful!

Jenga Math Review

A while back I posted about a used Jenga game I purchased at a Goodwill store.  Well, I finally finished it!  It took me a while because I didn't really know what to use it for or how to fix it up.



Well, I'm finally done and here is the final product!
I used an old plastic bin I had for
storage since the original
box wasn't in good condition. 
They all fit perfectly!

I used fine point permanent markers to make the game colorful.  I included various types of skills that my students need review on. Since the game blocks were in excellent condition and very smooth, it was easy to write on them with markers. 

TIP:  Use brand new fine tip markers.  For some reason, my used markers bled into the wood. 

One of my student groups already tried it out and they said it was "cool"! 

I hope these tips were helpful.  Let me know what you think!

UPDATE:  I was able to get a picture of Math Jenga in action.


I have my students seated in groups of four and I rotate stations around the room by groups.  Many students were anxious to get their turn at this station.  :D



Here is another great test review activity available at my Teachers Pay Teachers Store.
