Opening: I will begin today’s lesson with a cute and fun video. Though this video isn’t about baseball, it is very awesome and I couldn’t pass it up! I think it’s the perfect way to engage them and get them ready for the subtracting that’s to come for the day’s lesson! This is the video from YouTube: http://www.youtube.com/watch?v=QkPa9V2wtZs. I plan on playing this on my smart board and after each subtraction question he asks, I will pause it and we will say the answer as a class and then I will resume the video and we will see if we are right. I foresee first graders loving this! This song also has a ton of subtraction vocabulary terms.
Instruction: I will randomly do a few subtraction problems on the board with my students, letting them take turns to solve them and then I will explain what their activity is for their practice.
Practice: This activity is a lot of fun and will give students a lot of practice with subtracting. I will pair off all the students into groups of 2s. Each group will have a cupcake tin and a small, soft baseball. These materials will already be spread out in the room. Inside each of the cupcake tins will be half of a notecard that I have placed inside and written a subtraction problem on the front and a subtraction word problem on the back. Each student takes a turn throwing the baseball into a cupcake holder and then pulls that index card out, reads the problem and solves it on his or her own paper. Once they solve it, they will flip it over and hand the ball over to their partner.
Closing: I will call the students back to their desks and will take up their work for completion. To close, we will go back to the interactive website and choose another game (since there are SO many!) from this site to complete together. https://sites.google.com/a/leahfullenkamp.com/mrs-fullenkamp/math-1/subtraction. This time, I will not chime in to help them like I did on the first day closing. I will let them go up in pairs of two’s to answer the questions.
After Assessment:I will have my students give me a journal entry that is informative and gives me facts and a sense of closure to show they are understanding what we are doing. I will write a few questions on the board for them to give me written statements to do this and then I want a short summary at the end.
