:
"Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem."

Our Take:When solving word problems that involve addition and subtraction within 20, the first grader will use grade-appropriate strategies, such as writing an equation with a symbol for the unknown and drawing a picture.

These worksheets, games, and lesson plans can help students practise this Common Core State Standards skill.
