For those students that are struggling with subtraction facts up to 20 they can use the ten frame model to subtract. This is for those students that need to see it.
For students still struggling with basic facts up to 10. My students were struggling with basic facts such as 4+2 so I decided to create these paper size flash cards that I can use every morning for 5-10 minutes (and kids can use at centers). They are great because kids can see it at a distance. All you have to do is print, put on construction paper so it can stand out and laminate for every day use.
I did this for my second graders because they were still getting stuck on subtraction basic fact up to 10. So I printed them out and glued them to construction paper and laminated them. I was able to stand in the front of the classroom and for 5-10 minutes flash the cards.
This is a sheet that I made for my students to take home and practice everyday. This really helped the kids learn their skip counting. I stapled it to a manila folder and i also stapled a parent/student log where students and parents sign everyday that they practice. This really helped for them to be fluent in their skip counting.
