I teach second grade and a huge part of our math instruction is based on addition and subtraction facts. We encourage the students to practice these facts at home but not everyone does. With Quizlet flashcards, students can practice each set of addition and subtraction facts and then use them in different fun activities to study. Below are 4 sets of flashcards I have created for my students. I can easily send out the link to my flashcards or have students search for the fact group they are working on on the website.
