Building fluency with addition and subtraction is a critical area of focus for second grade math instruction. In addition to mastery of basic facts within 20, skip counting and other computations strategies learned from previous grades are applied. Students’ use of computation skills coincides with the ability to solve word problems involving money. This four-page activity requires student to apply these skills to present a handful of stamp-buying related questions.
