How can understanding the properties of addition and subtraction help us find more than one way to solve a problem?
Critical Thinking: Students will analyze problems and decide which property of operations would be most efficient to apply.
Adaptive Perseverance: Students will explore multiple methods to solve problems, understanding that there is more than one way to reach an answer.
Communication: Students will explain their reasoning and process for choosing and applying a specific property of operations in problem-solving.
What are the properties of operations, and how do they apply to addition and subtraction?
How can applying these properties change the way we approach solving a problem?
Can you think of a real-life scenario where using a property of operations could make solving a problem easier?
Students will identify and explain the properties of operations as they apply to addition and subtraction.
Students will demonstrate how to apply these properties to solve addition and subtraction problems more efficiently.
Students will apply the understanding of these properties to solve real-life mathematical problems.
1.OA.B.3: Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.)
