Geometry in kindergarten involves the basics of measurement, shapes, and spatial reasoning. Designed and reviewed by teachers, this guided lesson gives kids an overview of these concepts with clear instruction and engaging exercises. Geometry practice in kindergarten can help bolster the skills needed for higher-level concepts in the later grades. You can give kids even more practice by downloading and printing the accompanying worksheets.
Kids get the opportunity to make their own jungle board game and practice their math skills. They will cut out the game markers and dice to begin the game.
Use this rectangular prism cut-out to help your child learn more complex geometric shapes, or practice finding the surface area or volume of an object.
First grade geometry covers basic shapes, as well as an introduction to 3D shapes. Our team of curriculum experts designed the following guided lesson, which provides an overview of first grade geometric concepts and gives kids lots of opportunities for practice. If your child needs more support in a different format, check out the suggested first grade geometry worksheets.
This guided geometry lesson takes second graders on an exploration of 2D and 3D shapes. Kids will learn how to sort shapes, as well as partition them into halves, quarters and thirds. Tangrams are also featured within the exercise in order to give kids practical ways of practicing their new geometry skills. For more printable practice, try the geometry worksheets recommended by our curriculum advisors to accompany this lesson.
Build a solid geometry foundation with these hands-on shapes. Kids can practice identifying attributes of 2-D and 3-D shapes, then put their knowledge to the test by drawing and making 3-D shapes.
This final installment of our Second Grade Fall Review Packet offers five more days of engaging activities that will prepare incoming second graders for a new year of learning.
Get in shape for geometry! From 2D to 3D, polygons to prisms, your child will soon be a shape master. After a review of important terms and concepts, he will practice identifying real world shapes.
3D shapes are solid objects that have three dimensions. These dimensions are length, width, and height. While 2D shapes are flat, 3D shapes objects that have depth to them. A soccer ball is a 3D shape, also known as a sphere, while a circle on a piece of paper is a 2D shape. To learn more about the different names and properties of 3D shapes, see our resources below.
Get Started With 3D Shapes
3D shapes can be complicated to work with at first because they have strange names and properties that are different from the familiar 2D shapes. We’ve put together a list of some properties of common 3D shapes and common equations that can be used when working with 3D shapes.
3D Shape
Properties
Volume
Surface Area
Sphere
It has no edges or vertices (corners) It has one surface It is perfectly symmetrical All points on the surface are the same distance "r" from the center
4⁄3 × π × r3
4 × π × r2
Cylinder
It has a flat base and a flat top The base is the same as the top It has one curved side
π × r2 × h
2 × π × r × (r + h)
Cone
It has a flat base It has one curved side
1⁄3 × π × r2 × h
π × r × (r + s)
Cube
It has 6 Faces, each with 4 edges (and is a square) It has 12 Edges It has 8 Vertices (corner points), each is where 3 edges meet
(edge length)3
6 × (edge length)2
Triangular Prism
It has identical ends (triangles) and flat faces It has the same cross section all along its length
Base area × length
2 × base area + base perimeter × length
