This is a series of 21 posters that outline various mental math strategies for use in Number Talks discussions. The strategies come from examples used in the book Number Talks by Sherry Parrish, but I have put each one into a poster format so students can reference the strategies as they think.
Each strategy is on its own poster (preview is condensed)
Strategies included are:
Addition - Break it Down, Friendly Numbers, Making Tens, Doubles/Near Doubles, Compensation, Adding up in Chunks
Subtraction: Adding Up, Removal/Counting Back, Place
Value/Negative Numbers, Constant Difference, Adjust one Number
Multiplication: Repeated Addition, Friendly Numbers, Partial Products, Doubling and Halving, Breaking Factors into Smaller Factors, Area Model
Division: Repeated Subtraction, Multiplying Up, Partial Quotients, Proportional Reasoning
