Geometry Lesson Plans

Teachers often struggle to make sure they are covering all the concepts they need to teach in school. Geometry lessons build on each other, so it is important that this subject be taught very carefully with each idea building on the one before it. Nowhere is this more important than during the fourth grade. Concepts that teachers need to be sure to cover include angles, classifying quadrilaterals, lines of symmetry, and open and closed shapes. Much of the year will be spent studying polygons, including classifying these shapes by the number of sides and comprehending whether a shape is concave or convex. Another major occupation will be studying circles, including parts of a circle and finding a circle's diameter, radius, and circumference. Of course, teachers will also have to ensure that their students are well prepared in each of these subjects because their own success is often measured by how their pupils perform on standardized tests.
