Operations & Algebraic Thinking – 3rd Grade
Represent and solve problems involving multiplication and division.
Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
Drawings and equations help us solve word problems in situations involving equal groups, arrays, and measurement quantities.
Understanding the context and actions of a story problem helps us to interpret and represent mathematical equations.
