STUDENT ACCOUNTABILITY WITH NUMBER TALKS
1. Students use finger signals to nurture think time and strategy development.
2. Create anchor charts of student strategies.
3. Hold small-group number talks everyday.
4. Create and post class strategy charts.
5. Give students an exit problem using the discussed strategies.
Computational "Fluency"
What's the difference between
computational fluency and memorization?
"Computational fluency refers to having efficient and accurate methods for computing. Students exhibit computational fluency when they demonstrate flexibility in the computational methods they choose, understand and can explain these methods, and produce accurate answers efficiently. The computational methods that a student uses should be based on mathematical ideas that the student understands well, including the structure of the base-ten number system, properties of multiplication and division, and number relationships.”
Number Talks help students to...
add and subtract within 20, demonstrating fluency for addition and subtraction within 10, use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
