Addresses Standard: 1.NBT.B.2 This excerpt from a larger lesson is an introduction to place value for first grade students. The video begins after students have worked in groups to count out large numbers of popsicle sticks for a class project (footage not available). The class discusses and explores how making groups of ten makes it easier for mathematicians to count because it is an organized and efficient way to count large numbers of objects. This lesson exemplifies various indicators from all three Core Actions.
