We have moved from a focus on 2-D measurement (including perimeter and area) to looking at polygons and angles. Ask your student to explain the above chart to you! It might make your head spin, but they are working each day to learn the various characteristics of quadrilaterals. We are also focused on learning to recognize landmark angles (30, 45, 60, 90, and 180 degrees) and using these to build larger angles. Our Unit 4 assessment will be on Thursday, January 30.
