Count backwardsCounting down by ones, fives, and tens.6 skills
Count Backward by Ones
Given an oral prompt and no displayed sequence, recite the backward number-word sequence by ones from the requested starting point to 0, up to a starting point of 100.
Count Backward by Ones from Any Number

Count objectsCounting collections and recognizing small quantities.3 skills
Count Objects
Given a collection within the stated size and arrangement boundary, coordinate one count word with each object exactly once and state the final cardinality.
Instant Count Quantities Through 5
Given a briefly shown quantity from 1 through 5, recognize and name the quantity without counting each object.
Count Grouped Collections Extension
Given a collection organized into visible equal groups of five or ten with possible remaining single objects, determine and state its total cardinality through 100.
Produce objectsShowing a requested number of objects.2 skills
Produce a Requested Number of Objects
Given a spoken target and a larger available collection, select exactly the requested number of objects and stop at the target.
Produce a Requested Number Using Groups of Five and Ten Extension
Given a requested quantity and grouped objects, select or construct groups of five, groups of ten, or a mixture of groups and single objects whose total equals the target.
Explain countingPrinciples that explain how counting works.4 skills
The Last Number Said Tells How Many
After correctly counting a collection, state that the last number word said tells the total number of objects in the collection without recounting.
The Next Counting Number Means One More
Given a counted collection, predict that adding one object makes the total one greater and name the next counting number as the new total.
Counting Order Does Not Change How Many
Explain and demonstrate that a collection has the same cardinality when its objects are counted in a different order, including from the opposite end.
Moving Objects Does Not Change How Many
Explain and demonstrate that moving or rearranging every object in a collection, without adding or removing any, does not change its cardinality.
Reading numbersRecognizing numerals and connecting them to number names.1 skill
Read Numerals
Given a written numeral from 0 through 20 in mixed order, say the corresponding number name. No objects, counting, or numeral writing are required.
Writing numbersRepresenting spoken numbers and quantities with numerals.2 skills
Write a Spoken Number
Given only a spoken number from 0 through 20, write the corresponding numeral without seeing a numeral or number word.
Write How Many
Given a visible collection of 0 through 20 objects, write the numeral that represents its cardinality.
Shapes & positionRecognizing shapes and describing where things are.10 skills
Name Common Flat Shapes
Given one circle, triangle, square, rectangle, or hexagon without an answer label, say its most specific common shape name across varied sizes and orientations.
Compare Flat-Shape Properties
Given two flat shapes and several property statements, select the true comparison about their sides, corners, or equal side lengths.
Draw a Named Flat Shape
Given the spoken and written name of a flat shape, draw one recognizable instance without a tracing or copying guide.
Model a Flat Shape from a Familiar Object
Given a clear view of a familiar object's flat face or panel, draw the flat shape represented by its outside edge.
Place Objects Above or Below
Given two objects and a named vertical relation, place one object above or below the other from a fixed front viewpoint.
Name Familiar Solid Shapes
Given one familiar solid model without an answer label, say cube, sphere, cylinder, cone, or rectangular prism as its most specific common name.
Distinguish Flat and Solid Shapes
Given a picture representing a geometric figure, select whether the represented figure is flat (two-dimensional) or solid (three-dimensional).
Compare Solid-Shape Properties
Given two solid shapes and several property statements, select the true comparison about flat or curved surfaces and whether the solids can roll, stack, or slide.
Place Objects Beside One Another
Given two objects and a request to put them beside or next to one another, place one object adjacent to the other across varied left-right arrangements.
Place Objects In Front or Behind
Given two objects, an explicit front viewpoint, and a named depth relation, place one object in front of or behind the other using occlusion.
