Solve addition and subtraction word problems, and add and subtract within 10, by using concrete objects or drawings to represent the problem.

Unpacked Content


Students know:
  • Characteristics of addition and subtraction contexts such as putting together, adding to, taking apart, and taking from.


Students are able to:
  • represent quantities and operations physically, pictorially, or symbolically.
  • Strategically use a variety of representations to solve addition and subtraction word problems.
  • Use informal and mathematical language to communicate addition and subtraction representations.
  • Accurately compute sums and differences.


Students understand that:
  • both putting together and adding to can be viewed as addition.
  • both taking apart and taking from can be viewed as subtraction.
  • Mathematical problems can be solved using a variety of strategies and representations.


  • Concrete objects
  • Drawings
