Decomposing Numbers and SUPER DUPER Fluency Practice


One of our favorite fluency games in the classroom is the popular "Domino Dash". I don't know if we play it like everyone else out there but my kids love it! It is kind of like "War" with dominos. 2 students pick a domino and whoever says their number first gets to keep both dominos. My students have become pretty proficient with adding quickly through this game alone. 

However, I noticed something during our last round of assessments. What if they only have one number and they need to figure out what is missing? If you give a student 2 will they automatically know how to get to 5? to 10? We need some practice with this! 

So here is the plan. I made some cards that look like dominos with only one number. I will hold up a card, say "Make ____" (whatever number we are working on) and students will respond with the number they need to make the number. This can be an easy 5 minute warm up to math or a game to play during morning meeting. 
Decomposing numbers in kindergarten and first grade is an important foundational skill. Work on breaking apart numbers with these whole group, small group or individual materials and students will not only be learning new math concepts but working on fluency as well.
When I printed them out I printed them all on different colors so they will be easy to grab and know what number we are working on. I think it is important to work on one combination at a time but eventually the goal would be to be able to show a number and say ANY number for them to build to.

I also made a bunch of 5 frames and 10 frames filled and blank too for students to practice with. I think this will help a lot with their fluency and ability to quickly decompose a number to know what is missing. 

You can see this in my store HERE. I included the first set of cards in the preview so if you check that out you can try the Make 5 cards for free.
