Our math coach, Mrs. Rigatti, created this Parent Reference sheet about rounding. We hope you and your student find it helpful when completing homework or discussing the rounding concepts that have been introduced in Unit 1. Thanks for supporting your child!!!

In some ways, math instruction is very different today than it was when we were in school. Instead of rote memorization and skill drills, standards now emphasize number sense and problem solving skills. The following document is a handy resource guide to multi-digit addition and subtraction for Grade 3. This guide has been placed in your child's folder after the math tools tab for easy reference.
In this first unit, third graders will focus on and review a variety of place value concepts including addition and subtraction strategies, rounding, word problems involving money, and number comparisons (<, >, =). Students will also solve real world and mathematical problems involving perimeters of polygons. Rounding to the nearest 10 or 100 is an important new concept which requires a solid place value understanding. Solving two-step word problems using the four operations and representing these problems using equations with a letter standing for the unknown quantity also helps students to assess the reasonableness of answers using mental computation and estimation strategies. Third graders will also use $ and ¢ symbols to solve practical money problems.
