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.
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.
Students will love composing and decomposing two-dimensional shapes using tangram puzzle pieces. Use this plan alone or to frontload key vocabulary and concepts taught in the lesson plan **Know Your Shapes.**
Quadrilaterals are important shapes when it comes to geometry. While students won’t begin to learn about more complex quadrilaterals like the rhombus and trapezoid until about first grade, they are probably completely familiar with quadrilaterals like the square and rectangle. Help familiarize your child with these geometric shapes, or if they’re ready to tackle a more complex topic, use familiar quadrilaterals to introduce the concept of symmetry.
The concept of a quadrilateral is simple enough: it is a two dimensional shape that has four straight sides, is closed, and has interior angles that add up to 360 degrees. Working with quadrilaterals can help students develop early concepts of geometry, such as angles, graphing, and symmetry. Visualizing how angles function in the changing shapes of quadrilaterals develops important instincts in geometry. Likewise, understanding symmetry helps with future concepts of graphing. Let’s consider a few types of quadrilaterals:
Square: a square has four equal sides, four perfect right angles, and opposite sides are parallel.
Rectangle: a rectangle has two pairs of equal sides, four perfect right angles, and opposite sides are parallel.
Rhombus: a rhombus is a diamond looking shape. It has four equal sides, two pairs of equal angles, and opposite sides are parallel.
Parallelogram: imagine a rectangle that has been tipped to the side. It has two pairs of equal sides and two pairs of equal angles.
Trapezoid: trapezoids don’t necessarily need equal sides or angles. The only requirement is that two of the four sides are parallel.
