These are 10 problems I wrote for 1st grade. All the problems relate to St. Patrick's Day. 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, subtraction, part/part/whole, missing addend, money, elapsed time, patterns, estimation, shapes, non-standard measurement. These are ready to print or you can change the names to your own students' names for further engagement. Answer key is included.
