NUM
Numbers
(8 atoms)Perceptually subitize quantities through five
Names a briefly shown quantity from zero through five without counting, across both structured and unstructured arrangements.
Maintain one-to-one correspondence while counting
Pairs exactly one number word with each object in a collection so no object is skipped or counted more than once.
Use the final count word to state how many
After counting a collection, states that the final number word gives the total quantity without treating it only as a label for the last object.
Conserve number across order and arrangement
Recognizes that a set has the same number of objects when it is counted in a different order or rearranged without adding or removing anything.
Relate each successive number to one more
Explains and represents that the next number in the counting sequence names a quantity containing exactly one more object.
Compare concrete groups through 10
Compares two groups containing up to 10 objects and identifies one as greater than, less than, or equal to the other without requiring comparison symbols.
Compare written numerals from 1 through 10
Given two written numerals from 1 through 10, identifies which names the greater quantity or that the quantities are equal without requiring comparison symbols.
GEO
Shapes
(8 atoms)Describe positions as above or below
Describes one object's vertical position relative to another object using above or below correctly in either direction.
Describe positions as beside or next to
Identifies and describes when one object is beside or next to another object across varied arrangements.
Describe positions as in front of or behind
Describes one object's position as in front of or behind another object when the observer frame is visually or verbally established.
Name common two-dimensional shapes across size and orientation
Names circles, triangles, squares, rectangles, and hexagons when their size, proportion, or orientation varies.
Informally analyze and compare two-dimensional shapes
Compares two flat shapes by observable parts and attributes such as sides, corners, and equal side lengths without requiring a formal classification proof.
Model a named or real-world shape by building or drawing
Builds or draws a recognizable model of a named two-dimensional or three-dimensional shape, including shapes observed in the environment.
Distinguish two-dimensional from three-dimensional shapes
Classifies shapes as flat two-dimensional figures or solid three-dimensional objects while distinguishing a pictured representation from the object it represents.
Informally analyze and compare three-dimensional shapes
Compares two solid shapes by observable parts and behavior, such as flat or curved surfaces and whether they roll, stack, or slide.
MD
Measurement
(3 atoms)Identify and describe linear attributes
Identifies length, height, or width as the relevant measurable attribute of an object and describes it with appropriate comparative language.
Identify a penny as one cent and value up to 20 pennies
Recognizes a penny as a coin worth one cent and determines the total value of a collection of up to 20 pennies.
Directly compare weights as heavier or lighter
Directly compares the weight of two objects and describes the result as heavier, lighter, or the same weight.
OA
Operations
(1 atoms)FLU
Fluency
(3 atoms)Add accurately within 10
Finds sums with addends and totals within 10 accurately, using any mathematically valid strategy without a fluency requirement.
Find the part needed to make 10 using a model
Given a number from 1 through 9, uses objects or a drawing to find the missing part that makes 10 and records the result with a drawing or equation.
Subtract accurately within 10
Finds differences with starting quantities within 10 accurately, using any mathematically valid strategy without a fluency requirement.
