Additional finger(s) raised - additional solutions
Sign language for making a connection Benefits of Sharing & Discussing Computation Strategies:
Students have the opportunity to:
1. Clarify their own thinking
2. Consider & test other strategies to see if they are mathematically logical
3. Investigate & apply mathematical relationships
4. Build a repetoire of efficient strategies
5. Make decisions about choosing efficient strategies for specific problems The Role of Mental Math Critical for Understanding Place Value, Developing
Number Sense, Building Automaticity, Reasonableness
of Answers, etc. Purposeful computation problems Number Talks can be a purposeful vehicle for -
1. making sense of mathematics
2. developing efficient computational strategies
3. communicating mathematically
4. reasoning and proving solutions Helpful Hints:
-Select a designated location that allows you to maintain close proximity to your students for informal observations and interactions
-Provide appropriate wait time for the majority of students to access the problem
-Accept, respect, and consider all answers
