Here is a great set of 24 task cards for Valentine's Day. What a fun math activity to do with your students on Valentine's Day! These cards are aligned to the 2nd grade common core standards. Use with 2nd grade students to cover important problem solving skills, but also great for your 3rd graders who will be tested on these skills next year. Can be used with your whole class, in small groups, or great as a math center activity. They include both addition and subtraction problems that involve adding to, taking from, putting together, and taking apart. What a great way to differentiate for your students at all levels. Answer key included. Happy problem solving!
