I've noticed many of my students understand how to round, but they often round to the place! This great little checklist can be copied and taped right in to your students' math journals for easy revisiting when they forget all the steps to rounding to a specified place value.
File prints 6 per page (pdf)--feel free to print in black in white to save color ink.
I love distributing small, colorful reminders that are timely to the lessons to supplement students' handwritten notes. These little "cheat sheets" are visually appealing and keep students looking back until the skill is burned in the brain!
