Using Cuisenaire Rods

Last week, our school received exciting new math tools – cuisenaire rods! I’ve used these number rods before, and was thrilled to jump right-in with them this week in guided math groups. We are at a perfect point in math to spend an entire week getting hands-on practice with some 1st grade skills. 

With any math tool, we started with exploratory play. I introduced the cuisenaire rods by name, handed out a mat for using the rod (just 1 cm graph paper), and set the timer for 10 minutes. Why do we play first? My friends know we put first-things-first, so when we pull out these number rods, I want to make sure we are using them as math tools, not as toys. Giving students time to explore gives them this ‘play’ time so our later learning is focused.

Our first task after exploring the rods was to create a staircase. It was interesting to watch students create their staircases and see which students had to individually count/point the squares on each rod and which students could mental ‘hold’ the number as they counted.
Using Enriching Mathematics online (free), I was able to have students share their stairs on our SMART Board, as well. Our school also purchased a teacher-set of magnetic cuisenaire rods, but I haven’t broken those out yet. I hoping to try them out this week!
At this point, we transitioned into our guided math groups. We are learning about related facts (fact families) right now, so we started with a part/part/whole chart. I LOVED this visual representation of this skill. I gave my students 2 parts and they had to find the matching whole rod. After lots of practice, we bumped it up and I gave students a whole and a part. It was then their job to find the missing part (i.e. missing addends)!
Then, we transitioned to writing number sentences about our part/part/whole boxes. The cuisenaire rods are so hands-on, it’s perfect for my sweet and lows who struggle with fact families. They could physically manipulate the placement of rods (green first, yellow second…yellow first, green second). Additionally, it made the ‘Think Subtraction’ sentences SO much easier to coach. Students had the whole rod (the green plus the yellow) in their hands. They could then choose which rod to remove (subtract). As students did each step, they had to talk me through it. After we talked about it, we wrote it on our tables. Using cuisenaire rods made fact families such a ‘concrete’ concept rather than these random 4 number sentences – woohoo!

 In Chapter 5, Go Math also has us looking at different ways to compose numbers. Using our cuisenaire rods was a great opportunity to get hands-on practice with this skill. We started out with only the rods on the table (no markers). I handed each student a different whole and asked them to find other rods that were the same length. (Each student had a different whole to keep wandering eyes at bay). After students had time to find 5/6 different combinations, we went around the table and talked about the rods asking ‘How did you made them equal?’ Then, we made the connection to addition – finally, writing our addition sentences under each combination.

This is such fantastic practice for my friends that is has become a new math center using these house mats. It’s the perfect opportunity for students to get hands-on practice with equal number sentences and the house provides a structure that helps students to work independently. 

One group of my friends were ready to bump-up to finding equal equations, so I introduced the balances – (insert amazed faces of 1st graders here). This is the first time I’ve pulled out this math tool, and my friends were in awe. To start, we explored the beams and made predictions about what would happen if we put different rods on each platform. After exploring, I asked – “How could you make both sides balanced?”

Throughout 2 days of guided math, we learned that different combinations of the same number would balance because they had the same value.

Eventually (after MUCH practice and talking and hands-on experience), we wrote each side of the balance in terms of numbers. We’ll continue exploring this in the coming week, and I will introduce it to my other guided-math groups, as well. After teaching it once, though,

Well friends, these are a few different ways we’re using cuisenaire rods in our guided math structure. We are loving these hands-on tools. As a teacher, I love that they provide such a concrete model for some difficult math concepts.

If you don’t have cuisenaire rods, no worries! You can can pick up a small-group set of cuisenaire rods pretty affordably on Amazon. (FYI – when using them in small groups, I use 1 set for every 3 students) or use them online at Enriching Mathematics. 

So tell me, do you use cuisenaire rods in your classroom? If so, do you have any tips or tricks for using them? What’s your favorite way to use them? I’d love to hear what works for you!

    Thanks for sharing. =) The rods that I have access to do not join together and do not have a side that shows the segments… wish they did. But they are still useable and we have a ton of them, so I almost have enough for each student to have their own set! Now if their desks were only large enough…lol

    You do so many great things in your classroom! I'm curious as to how you take grades. We are required to take math, spelling, and reading grades, and I always struggle to come up with activities to grade. Any tips would be helpful!

    I’m looking for the house template – but your link doesn’t bring me to them. Any idea where I can find them? I could make them, but I don’t want to “reinvent the wheel” if I don’t have to!
