CCSS.Math.Content.1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. 

We continue to work on fact fluency in first grade.  Fact fluency is practiced each day at students’ independent centers.  Recently I introduced the “doubles” and “doubles plus one” strategies to my firsties.  They are so proud to be able to share all of the doubles they now know!

Introducing Doubles and Near Doubles: 

At the beginning of the week we we worked through understanding the Doubles and Doubles-Plus-1 (or near doubles) strategy with our work mats.  Students saw how knowing and understanding doubles helped them to solve many more number sentences quickly.  The idea of doubles is that when you have those facts memorized (1+1, 2+2, 3+3, ect.) you then can add problems such as 1+2, 2+3, 3+4 by just adding one to the sum.

Centers, centers and more centers:

After learning about the doubles and near doubles math strategies students were off to practice independently during math centers with their peers.  I wanted my students to be able to explore this math strategy with hands on activities that helped them develop this strategy.

Students sorted doubles and near doubles math facts.  
Students played Bump with partners to continue practicing doubles and near doubles math facts.  
Students played “Doubles Dice on Ice!”  another math game to promote fact fluency.  


We used the SmartBoard during centers to match up some “Ladybug Doubles!”
These games and many more can be found in my Doubles and Near Doubles Math Centers. I have both a winter and a spring version.  Click here or on the picture below to see more about these games and activities.    
Jump Game:
Students loved this game!  I used butcher paper to create a large game mat and wrote all of the doubles sums on it (I even added some tricky ones to challenge my higher students.)  One student was in charge of reading the doubles fact while two other students “jumped” to the correct sum!  Although the game was called “Jump” I quickly told students they need to walk and “hop” to the numbers because some of my little friends were getting a little too excited at the idea of jumping across the game board!  Students had fun hopping to squares to practice their doubles facts!
What good would a Saturday be without a freebie? 🙂 We used these doubles task cards this week to practice our doubles and near doubles math facts during transitions.  They are great because some of my kids still need the visual of counting/seeing the blocks and others add the doubles facts without the pictures.   Click here or on the picture below to grab your set!
“How many doubles facts do you know?”
This week finished with an informal assessment.  I asked my students question that now seemed simple to many of them, “How many doubles facts do you know?” Students were then given about 3 minutes to write as many doubles facts as they are able.  It was awesome to see the excitement as students filled their white boards with addition sentences.  Many students also realized as they were adding that their doubles facts followed a pattern of counting by two’s which allowed them to reach even higher numbers!

Happy Saturday!

  1. Love the jump on it game. I did the same thing with doubles and near doubles as well as adding 10 and 9. Kids love it! I also made a version to play on the table where kids cover the answer with their hand slap jack style.

    Love your informal assessment asking kids to write all the doubles they know. My first graders would LOVE this. Especially on a white board. I asked them to write all the numbers they knew a few weeks ago and they could not wait to fill up their boards, show them to me and erase and keep writing.

  2. Great article! I just wanted to say this post is right on the money. Apps are difficult to market, and games specifically have there own challenges. Video is definitely one of the best tools to get started with, and search engines love video. Most apps need explanation with a voice over, but most games dont, so you really need to present the game play in an enticing way and keep it short. You can make one yourself easily with your developer tool and a decent screen recorder. It takes some time but its well worth it. You could also just pay somebody to do it. I personally have used blue fortress media to make mine, but I know there are other good ones like appvj, wyzowl, and demo fuck. Either way good luck to you! And once again great article.
