SALTA 1st grade

1.G.1 1.G.2

Strand: Geometry First grade students will reason with shapes and their attributes.

Topic 14: Reason with Shapes and Their Attributes Pick a Project • Tower Shapes • Real Reflections • Tile Art • Robot Helpers 14-1 Use Attributes to Define Two- Dimensional (2-D) Shapes 14-2 Defining and Non-Defining Attributes of 2-D Shapes 14-3 Build and Draw 2-D Shapes by Attributes 14-4 Compose 2-D Shapes 14-5 Compose New 2-D Shapes from 2-D Shapes 14-6 Use Attributes to Define Three- Dimensional (3-D) Shapes 14-7 Defining and Non-Defining Attributes of 3-D Shapes 14-8 Compose with 3-D Shapes 14-9 Problem Solving: Make Sense and Persevere

Topic 14:

• Triangle • Hexagon • 2-D shapes • Attributes • Rectangle

Standard 1.G.1 Distinguish between defining attributes ( for example triangles are closed and three-sided ) versus non-defining attributes ( for example, color, orientation, overall size ); build and draw shapes that possess defining attributes. Standard 1.G.2 Compose shapes. a. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) to create a composite shape, and compose new shapes from the composite shape. b. Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape. First grade students do not need to learn formal names such as “right rectangular prism.”

• Square • Three-

dimensional (3- D) shapes

• Flat surfaces • Cylinder • Cone • Cube • Rectangular prism

• Edges • Faces • Sphere

Topic 14 Manipulatives • Measuring Tools • Pattern Blocks • Fractions of Circles • 3-D Shapes • Cubes • Ones cubes
