This PDF printable is great for students learning their key words in addition and subtraction problem solving. It includes just a few words for each operation for easy reference by your students.
Ideas for this:
1. Print and enlarge on a poster maker for your wall
2. Shrink and print one for each student to place in their math journal/folder
3. Use in front of students in small math groups
My students use this tool on a daily basis and eventually recognize the key words independently!
