Private: Learning Math: Number and Operations
Classroom Case Studies, K-2
Watch this program in the 10th session for K-2 teachers. Explore how the concepts developed in this course can be applied through case studies of K-2 teachers (former course participants) who have adapted their new knowledge to their classrooms.
In This Session:
Part A: Observing a Case Study
Part B: Reasoning About Number and Operations
Part C: Problems That Illustrate Reasoning About Number and Operations
Homework
In the previous sessions, you explored number and operations as a mathematics learner, both to analyze your own approach to solving problems and to gain some insight into your personal conception of number and operations. It may have been difficult to separate your thinking as a mathematics learner from your thinking as a mathematics teacher — most teachers think about teaching as they are learning and think about learning as they are teaching. In this session, we shift the focus to your own classroom and to the approaches your students might take to mathematical tasks involving number and operations concepts.
As in other sessions, you will be prompted to view short video segments throughout the session; you may also choose to watch the full-length video for this session. See Note 1 below.
LEARNING OBJECTIVES
In this session, you will do the following:
• Explore the development of number and operations concepts at your grade level
• Examine children’s understanding of number and operations concepts
• Explore how you would teach problems involving different number and operations concepts
Notes
Note 1
This session uses classroom case studies to examine how children in grades K-2 think about and work with number and operations. If possible, work on this session with another teacher or a group of teachers. Using your own classroom and the classrooms of fellow teachers as case studies will allow you to make additional observations.
Key Terms
Previously Introduced
even numbers
Even numbers are integers divisible by 2. Any number that ends with the digit 0, 2, 4, 6, or 8 is an even number.
odd numbers
Odd numbers are integers not divisible by 2. Any number that ends with the digit 1, 3, 5, 7, or 9 is an odd number.
