Number Sense, Addition, and Subtraction
From counting and cardinality through place value, this minicourse will look at the big ideas relating to
number, addition & subtraction from whole numbers to fractions, the strategies students utilize in developing
those big ideas, and models that promote concrete understanding. Our discussions will focus on sharing
classroom practices that foster students’ growth across the landscape and take advantage of the range of grade
level perspectives that will be represented. Number talks, number strings, tape diagrams, tools for thinking
including the rekenrek and Digi-Blocks, all will be an integral part of the course as we consider how best to
develop students conceptual understanding in concrete and pictorial representations and that lead to more
abstract thinking. The content in Landscapes I will be the basis for development of ideas central to the focus
of Landscapes II & III coming in July.
