(I) Compose and decompose numbers up to 10 with objects and pictures.

(Y1) Count collections to 100 by partitioning numbers using place value (ACMNA014)

K.NBT.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

(A) Give an example of a measurable attribute of a given object, including length, capacity, and weight

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

(F) Use direct and indirect comparisons to decide which is longer, heavier or holds more, and explain reasoning in everyday language (ACMMG006)

K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

(E) Classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size

(F) Sort and classify familiar objects and explain the basis for these classifications. Copy, continue and create patterns with objects and drawings (ACMNA005)

K.MD.3 Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.

(A) Give an example of a measurable attribute of a given object, including length, capacity, and weight

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

(E) Tell time to the hour and half hour using analog and digital clocks.

1.MD.3 Tell and write time in hours and half-hours using analog and digital clocks.

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

(F) Use direct and indirect comparisons to decide which is longer, heavier or holds more, and explain reasoning in everyday language (ACMMG006)

K.G.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

(A) Identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles

(D) Identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably

(E) Classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size

K.G.2 Correctly name shapes regardless of their orientations or overall size.

(A) Identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles

K.G.4 Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).

(B) Identify three-dimensional solids, including cylinders, cones, spheres, and cubes, in the real world

(F) Sort and classify familiar objects and explain the basis for these classifications. Copy, continue and create patterns with objects and drawings (ACMNA005)

K.G.3 Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").

K.G.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

(F) Compose two-dimensional shapes by joining two, three, or four figures to produce a target shape in more than one way if possible

(Y4) Compare and describe two dimensional shapes that result from combining and splitting common shapes, with and without the use of digital technologies (ACMMG088)

K.G.6 Compose simple shapes to form larger shapes. For example, "Can you join these two triangles with full sides touching to make a rectangle?"
