Geometry Terms

We know that as students move up in grade levels, math concepts and vocabulary terms become more advanced. This is certainly true when it comes to fourth grade geometry terms. Students will not only be asked to apply vocabulary they have used previously, but they’ll also learn additional fourth grade math vocabulary that will help them learn new skills and concepts.

While students have learned basic shapes by this age, they begin to spend more time on the properties of shapes. They’ll use a more extensive vocabulary to identify and describe geometric shapes and figures. Students will identify polygons using attributes like sides, angles, and vertices. They’ll be expected to identify solid figures such as cubes, cylinders, spheres, cones, prisms, and pyramids by using edges, vertices, and faces. They’ll spend time on points, lines, line segments, and rays. They’ll be asked to classify angles as right, obtuse, or acute and to classify triangles as right, acute, or obtuse, as well as equilateral, isosceles, or scalene. Circles will be used to identify the radius and diameter and calculate each. Students will also apply the concepts of similar and congruent figures, transformations, and symmetry.

There will also be new geometry terms in fourth grade math for coordinate geometry. Students will be asked to find and plot ordered pairs on a coordinate grid. They’ll also need to give distance and directions on the grid.
