Friday Freebie - Magic Number Cards

In the beginning of the school year, I work with my students on mental math strategies and basic addition. (Sometimes, this takes longer than just the beginning of the school year.) One of my favorite ways of doing this is with Guess My Number Cards.

What are Guess My Number Cards?
Guess My Number Cards are a great way for students to practice simple addition of numbers between 1 and 31. 

How to Use the Cards
1. Tell students that you are thinking of a number between 1 and 31. 2. Look at each card.If the number is there, tell the students, "Yes." If it is not on there, tell the students, "No." 
3. Students then guess the number. If students know the trick, they should be able to guess the answer correctly.

* This is especially fun to play in the beginning of the year by having students pick a number, and you guess it correctly! I love hearing them guess how I was able to find the answer.

The Trick

The first number in the upper left hand corner is so important to finding the answer. You add the numbers of all the cards that have the number to find the answer.

For example, if my number was only on these two cards, I would add the 1+2. My answer is 3.

Freebie Time

The cards are free for you - a large class set as well as a small set for durability.  Click here to get your freebie! 

Please note: I laminated my cards onto colored paper and laminated mine for durability.

Bonus: This makes a GREAT filler activity when you have a couple of extra minutes that need to be filled.
