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. The four-page Post Office Problems template requires students to apply these skills to present a handful of stamp-buying-related questions.
Editor's Note: This blog is the second in a series of posts from former math specialist Scott Loomis on the real world math templates he has created for Wixie and how you can use and modify them for your own awesome performance tasks. You can read the backstory on his experience and expertise below.
