My students have been so hard at work on those addition and subtraction fast facts! We have made a bucket full of flash cards to use in addition to our addition self correcting puzzles and our subtraction self correcting puzzles, and it’s really paid off. We take our one minute quizzes every day and the kids get so excited when they pass a new level and get to color a new shape. My door is now becoming very full of stars (for addition) and moons (for subtraction). I have one student who has mastered them all and is bugging me to finish the multiplication quizzes so she can start earning clouds. Hopefully I’ll get them done this week! Here’s some pictures of what we’ve been doing with addition and subtraction. Grab a FREE copy of the reward system from TPT or Raki’s Shop.
My students were having a bit of trouble understanding the difference between addition and subtraction. We did a variety of activities to help them understand, including using manipulatives, pictures, and putting two equations with the same numbers, but different signs right next to each other (5+3=8 5-3=2). However, the thing that worked the very best was to let them come up with their own word problems. At first, they were just excited to be able to use each other’s names, but as they got to drawing, they really understood all of a sudden that in addition you have two separate groups, where as in subtraction you have one group and you are giving some away. It’s also made my problem solving center run so much smoother! Here’s what we did:
1st – We wrote an addition word problem using the names of our friends. We also drew a picture to represent our word problem.
2nd – On the back, we wrote the addition fact that would solve the word problem we created.
3rd – We had each student’s page bound into a book and placed it on the “warm shelf” to be read over and over.
4th – Repeat Steps 1-3, with a subtraction fact.
5th – Had a whole class discussion about the difference between addition and subtraction.
