Common Core State Standards with Grade 3 Addition Word Problems Worksheet

This Grade 3 addition word problems worksheet primarily supports CCSS.MATH.CONTENT.3.NBT.A.2: fluently add and subtract within 1,000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. Word problems also support CCSS.MATH.CONTENT.3.OA.D.8 when students solve two-step word problems using the four operations; the multi-step items here focus on addition. The exact standard fit depends on the numbers and strategies a teacher asks students to use.
