Shapes can have multiple sides: some straight, some curved.

‍The video begins by listing some attributes of common shapes. Video 1: Understanding Basic Shapes and Attributes

Create a shape when given a list of defining attributes.Ģ Videos to Help You Teach Common Core Standard: 1.GA.1īelow we provide and breakdown two videos to help you teach your students this standard.

Identify basic 3D shapes: cubes, right circular cones, right circular cylinders, etc.

Identify basic 2D shapes: rectangles, squares, trapezoids, triangles, etc.

Understand and explain the difference between defining and non-defining attributes (i.e.

Students who understand this principle can: three thirds, four fourths, etc.) They will also learn that the “equal shares of identical wholes” do not need to the same shape to equal each other (2.G.2-3).Ĭommon Core Standard: 1.GA.1 - Distinguish between defining attributes versus non-defining attributes They will also be able to cut shapes into equal parts and deepen their understanding of “part and whole relationship,” explaining that a whole can be made up of parts (i.e. Your students will learn to identify more complex shapes: triangles, quadrilaterals, hexagons and cubes (2.G.1). By understanding halves and fourths, your students will be able to work with, draw, and analyze shapes. This 1st grade skill of understanding halves and fourths will help your students when they move onto 2nd grade. They should also be familiar with making simple shapes to form larger shapes (K.G.6). squares, circles, triangles, etc.) and using formal and informal language to analyze and compare the shapes (K.G.1-3). Your students should be familiar with the Kindergarten skill of naming regular shapes (i.e. Then, we provide a breakdown of the specific steps in the videos to help you teach your class. Below we show two videos that demonstrate this standard.

Understanding and identifying basic 2D shapes based on their attributes is a first grade, Common Core math skill: 1.GA.1.
