These are 10 problems I wrote for 1st grade students. All the problems relate to Valentine's Day and there is a heart border around each page. Each problem has 3 different number sets so you can differentiate, as well as an extension problem for extra challenge. The skills they encompass are: problem solving, multi-step problems, time using a calendar, addition, addition start unknown, part/part/whole, subtraction, place value and subtraction change unknown. These are ready to print or you can change the names to your own students' names for further engagement. ANSWER KEY IS INCLUDED.
