My class has been working on two-digit addition with regrouping in recent weeks, and we're getting ready to move on to other math strands. Not wanting my students to forget this important skill, I've created an addition challenge that I'm using as bell work upon entry first thing in the morning.
I have a 100 chart hanging in one corner, and each day "Swiper" pulls two numbers from it.
The students are required to identify the missing numbers, then find their sum. I created little "ballots" that reflect the strategy we're using for addition.
The little cloud on the right-hand side is called our "Thinking Space" and is where the students first show the addition of the ones digits. After doing this, we have a rhyme that helps with the regrouping:
10 or more, move the tens next door.
9 or less, let the ones rest.
I take a peek at the solutions, and they glue the slip into their math notebook. If the student gets the answer correct on the first try, they earn a stamp or punch on their Swiper Addition Challenge card.
When they reach 10, they get to choose something from the classroom treasure chest. I am hoping that this regular practice will keep these addition skills sharp! If you'd like to try this in your own classroom, you can click the images above to grab free copies of the punch card and "ballot"! I'd love to hear what you think, or what you do in your classroom to motivate your students to keep these skills sharp!
