Then, their partner says, "Lose a cube!" and they take away one cube from the train.
After that, the other partner writes the number sentence to show and solve the subtraction problem they made with their cube train.
They continue to play the game with different numbers of cubes on the train; taking away 1 every time. My students enjoyed it so much that they asked me if they could play it as a fast finisher activity later in the week if they ever finished their work early! Music to this teacher's ears!
After a few days of putting our subtraction skills into practice, I was feeling a bit stagnant in how we had been practicing creating and solving number sentences, so I came up with a fun little game called Flower Power Subtraction! I made a flower with 10 petals and labeled each one with numbers 1-10. Then I created a stem and made 10 leaves to go it.
Whoever threw the beanbag removes that many leaves from the stem. Since this one landed on 8, this student is taking 8 leaves off of the flower to see how many we have left over.
Then, using whiteboards, they wrote the number sentence to show their work! (I realize this isn't the number sentence that matches the picture above, but you get the idea).
They had SO much fun playing this game... they begged me to play it again! So for the next day, I whipped up a quick little recording sheet to go with it. You can download it for free by clicking on the picture below!
To switch the game up a bit, we also played it so that one student threw a beanbag on the flower and another rolled a dice. They had to decide which number was more, then create a subtraction problem using the 2 numbers we landed on. It was a quick little mini-lesson on how the bigger number always has to come first in our subtraction problems!
I'll probably roll this game out a few more times during our math time this week. I love when a new idea works out with the kids so well! They are getting faster and faster at solving their number sentences. Happy Sunday, everyone! Hope you have a great week.
