How can we use objects, drawings, and equations to find solutions to problems that involve adding three numbers, where the total is 20 or less?
Adaptive Perseverance: Students will experiment with different problem-solving methods (objects, drawings, equations) and persist through challenges.
Critical Thinking: Students will analyze word problems and decide which method (objects, drawings, equations) best represents the solution.
Communication: Students will articulate their problem-solving process and reasoning in both oral and written forms, demonstrating their understanding.
How can objects around us help us visualize and solve word problems involving the addition of three numbers?
In what ways can drawings and equations make it easier to understand and solve addition problems with three numbers?
How can we use a symbol for an unknown number to represent and solve word problems that involve adding three numbers?
Students will demonstrate the ability to solve word problems involving the addition of three whole numbers with sums less than or equal to 20, using objects, drawings, and equations.
Students will be able to represent word problems with equations, using a symbol for the unknown number.
Students will share and explain their problem-solving process and reasoning, using objects, drawings, or equations.
1.OA.A.2: Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
