IB: Where we are in Place and Time
About the Mathematics in This Unit
Our class is starting a new mathematics unit about geometry and measurement called Perimeter, Area, and Polygons. During this unit, students measure length by using U.S. standard units (inches, feet, yards) and metric units (centimeters, meters). They investigate characteristics of triangles and quadrilaterals (4-sided polygons). They use right angles as a reference to identify other angles as being greater than or less than 90 degrees. Students solve problems about perimeter (the length of the border of a figure) and area (the measure of how much flat space a figure covers).
