In this two-lesson unit, from Illuminations, virtual hundred boards and calculators furnish a visual way of highlighting and displaying various patterns and relationships among numbers. Using calculators and hundred boards together encourages students to communicate their thinking with others. Students display patterns on a calculator and on a hundred board simultaneously, and then examine number patterns, using a calculator to move beyond 100.
