Cluster:
Reason with shapes and their attributes.

Standard:
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.

Cluster:
Reason with shapes and their attributes.

Standard:
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.

Footnote:
Students do not need to learn formal names such as “right rectangular prism.”

Cluster:
Reason with shapes and their attributes.

Standard:
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.

Cluster:
Measure lengths indirectly and by iterating length units.

Standard:
Order three objects by length; compare the lengths of two objects indirectly by using a third object.

Cluster:
Measure lengths indirectly and by iterating length units.

Standard:
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

Cluster:
Tell and write time.

Standard:
Tell and write time in hours and half-hours using analog and digital clocks.

Cluster:
Represent and interpret data.

Standard:
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

Cluster:
Extend the counting sequence.

Standard:
Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

Cluster:
Understand place value.

Standard:
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: 10 can be thought of as a bundle of ten ones—called a “ten.”

Cluster:
Understand place value.

Standard:
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
