In this unit, students learn and practice efficient counting strategies. They use connecting cubes, connecting links, and number lines as tools for counting and comparing numbers, and they make connections between these representations. Students use the counting strategies to solve addition problems. In the last lesson, students begin to collect and record data on a data table for the type of sky each day.
