Introduction: Did you know that there are eight problem structures for multiplication and division? It is important to identify what information is given and what is missing in order to determine the correct operation to use. Completion Instructions: . Write a contextualized example for each of the multiplication and division problem structures below and write out the equation that represents the correct equation, including the missing variable but do not solve (ex 12x(?)=12). . After completing, post three on the discussion board (don't share the problem structure, just the example) . Respond to a peer's problems and identify the correct equation and problem structure for their three problems. 1. Equal Groups: (Whole Unknown) 2. Equal Groups: (Size of Groups Unknown) 3. Equal Groups: (Number of Groups Unknown) 4. Comparison: (Product Unknown) 5. Comparison: (Set-size Unknown) 6. Comparison (Multiplier Unknown) 7. Combination: (Product Unknown) 8.Area and Array
