Students explore patterns in this unit. In Lesson 1, students collect, record, and analyze winter weather data and compare patterns to the patterns they found in the fall weather data collected in Unit 1. Students then look for patterns in the addition facts while analyzing an Addition Facts I Know chart introduced in Lesson 2. Students then identify, describe, and extend growing and repeating patterns that are represented with drawings, number lines, and the 100 Chart. They use these patterns to build number sense and make connections to number operations. Students then extend this use of pattern by composing shapes with smaller shapes along lines of symmetry. In the last lesson, students look for patterns on the face of an analog clock.
