OVERVIEW Show All | Hide All | Top

In this unit, students will explore 2D and 3D shapes and fractions.  Students will be able to recoganize the attributes of 2D and 3D shapes. Students will use attibutes to build and draw 2D and 3D shapes.  Students will be able to take 2 shapes and create a new shape.  Students will divide circles and rectangles into halves and fourths.  Students will prove that the more people you share with the smaller pieces they will receive.

1.G.1:

Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

 1.G.2:

Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or 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.

 

1.G.3

Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
