This video tutorial, led by Simone, covers fifth-grade math focusing on operations and algebraic thinking. It includes a series of questions that explore concepts like PEMDAS, equivalent expressions, word problems, error analysis, and properties of operations such as associative, commutative, and distributive properties. The video also demonstrates how to calculate the area of a rectangle, use tables and graphs, and write algebraic expressions. Each section is designed to reinforce understanding through practical examples and encourages viewers to engage with additional resources.

• Step 2

• No mistake

• Step 1

• Step 3

Which expression demonstrates the associative property?

• 5 + (3 + 6) = (5 + 3) + 6

• 5 * 3 = 3 * 5

• 5 + 3 = 3 + 5

• a(b + c) = ab + ac
