This is a template I use with my students in my special education class to work on rounding. I put it in a dry and erase sleeve and the student writes the number at the top. They then round it to the nearest, ten, hundreds, thousands etc in the first box and the second box round it up. Then they can look at the neighbor and then find which side the neighbor is in and this helps guide them to the answer. Its a great visual for my students.
I used this worksheet to help with the understanding of fact families and how they are related to each other. It's a fun visual to use for those who are struggling.
