About the Math

 Skills and concepts below are learning goals for this standard.

  • Represent addition word problems with objects or drawings.
  • Represent subtraction word problems with objects or drawings.
  • Add within 10. 
  • Subtract within 10.
  • Solve addition and subtraction word problems using objects and drawings.

When introducing addition and subtraction problems, make sure you are incorporating the various problem structures (refer to the "Problem Solving" page). Addition and subtraction problems are divided into categories based on the kinds of relationships that are involved. These include join problems, separate problems, part-part whole problems, and compare problems. Students do not need to know the structures but teachers should make sure when they are creating problems that all structures are represented.
