These flashcards can be used in a variety of ways! I use gray for the numbers so that my students can trace and write each fact with a marker or crayon on their own. The flashcards are easily grouped so you can focus on one set of facts at a time. You may want to print on cardstock and use whole-group, or have your students work on independently. They can also be used with partners, in a math center, or as an at-home resource. I find the picture visuals are helpful for students to actually see how much they are "taking away". You may choose to edit them to fit your needs! I hope they are useful for you!
