Session 1: Introduction to Number Sense, Developing Mental Images, and Number Talks
What is it and how can we help our students?
Number sense can be developed by using contexts from word problems and well-orchestrated classroom discussions known as number talks. Writing your own grade level appropriate problems can help students explore the 11 types of problems within addition and subtraction and encourages the development of thoughtful questioning by both students and teachers. The continuum of strategies students typically use to solve problems will be a focus, allowing teachers to predict, assess, and describe the level students are at in solving problems. Understanding and discussing the continuum of solution strategies encourages greater sophistication in problem solving and deepens number sense among students.
- Teachers will be able to conduct a number talk with a group of students.
- Teachers will be able to write 11 different types of addition/subtraction word problems.
- Teachers will be able to identify and name the various strategies that children use to solve addition/subtraction problems.
Goal is not to just find the best solution strategy but to open your students’ eyes to having more than one way to do the problem. Goal is to create more than one way not adopt the most sophisticated strategy, conversations about efficiency come with time. Focusing on efficiency right away does not make sense if someone only has one way to solve a problem. They need to have more than one strategy choice to compare different ways.
