Compose and distinguish between two-and three-dimensional shapes based on their attributes.

Standard:

CC.2.3.1.A.2

Description:

Use the understanding of fractions to partition shapes into halves and quarters.

Standard:

MA.1.FR.1.1

Description:

Partition circles and rectangles into two and four equal-sized parts. Name the parts of the whole using appropriate language including halves or fourths.

Standard:

1.G.A.1

Description:

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.

Standard:

1.G.A.2

Description:

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.

Standard:

1.G.A.3

Description:

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.

Standard:

MA.1.GR.1.1

Description:

Identify, compare and sort two-and three-dimensional figures based on their defining attributes. Figures are limited to circles, semi-circles, triangles, rectangles, squares, trapezoids, hexagons, spheres, cubes,rectangular prisms, cones and cylinders.

Standard:

MA.1.GR.1.3

Description:

Compose and decompose two-and three-dimensional figures. Figures are limited to semi-circles, triangles, rectangles, squares, trapezoids, hexagons, cubes, rectangular prisms, cones and cylinders.

Standard:

MA.1.GR.1.4

Description:

Given a real-world object, identify parts that are modeled by two-and three-dimensional figures. Figures are limited to semi-circles, triangles, rectangles, squares and hexagons, spheres, cubes, rectangular prisms, cones and cylinders.

Standard:

1.6.A

Description:

classify and sort regular and irregular two-dimensional shapes based on attributes using
informal geometric language;

Standard:

1.6.B

Description:

distinguish between attributes that define a two-dimensional or three-dimensional figure
and attributes that do not define the shape;

Standard:

1.6.C

Description:

create two-dimensional figures, including circles, triangles, rectangles, and squares, as
special rectangles, rhombuses, and hexagons;

Standard:

1.6.D

Description:

identify two-dimensional shapes, including circles, triangles, rectangles, and squares, as
special rectangles, rhombuses, and hexagons and describe their attributes using formal
geometric language;

Standard:

1.6.E

Description:

identify three-dimensional solids, including spheres, cones, cylinders, rectangular prisms
(including cubes), and triangular prisms, and describe their attributes using formal
geometric language;

Standard:

1.6.F

Description:

compose two-dimensional shapes by joining two, three, or four figures to produce a
target shape in more than one way if possible;

Standard:

1.6.G

Description:

partition two-dimensional figures into two and four fair shares or equal parts and describe
the parts using words; and

Standard:

1.6.H

Description:

identify examples and non-examples of halves and fourths.
