Mathematics | Kindergarten
In Kindergarten, instructional time should focus on two critical areas: (1)
representing, relating, and operating on whole numbers, initially with
sets of objects; (2) describing shapes and space. More learning time in
Kindergarten should be devoted to number than to other topics.
(1) Students use numbers, including written numerals, to represent
quantities and to solve quantitative problems, such as counting objects in
a set; counting out a given number of objects; comparing sets or numerals;
and modeling simple joining and separating situations with sets of objects,
or eventually with equations such as 5 + 2 = 7 and 7 – 2 = 5. (Kindergarten
students should see addition and subtraction equations, and student
writing of equations in kindergarten is encouraged, but it is not required.)
Students choose, combine, and apply effective strategies for answering
quantitative questions, including quickly recognizing the cardinalities of
small sets of objects, counting and producing sets of given sizes, counting
the number of objects in combined sets, or counting the number of objects
that remain in a set after some are taken away.
(2) Students describe their physical world using geometric ideas (e.g.,
shape, orientation, spatial relations) and vocabulary. They identify, name,
and describe basic two-dimensional shapes, such as squares, triangles,
circles, rectangles, and hexagons, presented in a variety of ways (e.g., with
different sizes and orientations), as well as three-dimensional shapes such
as cubes, cones, cylinders, and spheres. They use basic shapes and spatial
reasoning to model objects in their environment and to construct more
complex shapes.

4. Understand the relationship between numbers and quantities; connect
counting to cardinality.
- Literature connection: Let's Count
a. When counting objects, say the number names in the standard
order, pairing each object with one and only one number name
and each number name with one and only one object.
b. Understand that the last number name said tells the number of
objects counted. The number of objects is the same regardless of
their arrangement or the order in which they were counted.
c. Understand that each successive number name refers to a quantity
that is one larger.
5. Count to answer “how many?” questions about as many as 20 things
arranged in a line, a rectangular array, or a circle, or as many as 10
things in a scattered configuration; given a number from 1–20, count
out that many objects.
Compare numbers.
6. Identify whether the number of objects in one group is greater than,
less than, or equal to the number of objects in another group, e.g., by
using matching and counting strategies.1
- Greater Than, Less Than or Equal? Helping Kids Compare Numbers
- Cynthia Lanius' Lessons: Which is More?
7. Compare two numbers between 1 and 10 presented as written
numerals.
Operations and Algebraic Thinking K.OA
Understand addition as putting together and adding to, and understand
subtraction as taking apart and taking from.

than one way, e.g., by using objects or drawings, and record each
decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
4. For any number from 1 to 9, find the number that makes 10 when
added to the given number, e.g., by using objects or drawings, and
record the answer with a drawing or equation.
5. Fluently add and subtract within 5.
1Include groups with up to ten objects.
2Drawings need not show details, but should show the mathematics in the problem.
(This applies wherever drawings are mentioned in the Standards.)
Number and Operations in Base Ten K.NBT
Work with numbers 11–19 to gain foundations for place value.
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 (e.g., 18 = 10 +
8); understand that these numbers are composed of ten ones and one,
two, three, four, five, six, seven, eight, or nine ones.
Measurement and Data K.MD
Describe and compare measurable attributes.
1. Describe measurable attributes of objects, such as length or weight.
Describe several measurable attributes of a single object.
- Lesson: Spud Stuff
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.
Classify objects and count the number of objects in each category.
3. Classify objects into given categories; count the numbers of objects in
each category and sort the categories by count.3
- Sorting Attribute Blocks
- Activity: Guess My Button
Geometry K.G
Identify and describe shapes (squares, circles, triangles, rectangles,
hexagons, cubes, cones, cylinders, and spheres).
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.
- Literature Connection: My Very First Book of Shapes Eric Carle (1974) This is a wordless, split, board book, where the lower pages have a colorful picture and the upper ones have corresponding shadows but in a different order. Children are to flip the pages until they match the picture to the shadow. This book does not fit into the pattern that encourages children, parents, and teachers to think that "learning your shapes" means naming just circle, square, triangle, and rectangle and learning these imperfectly! (Scroll down to the set of activities suggested for this book around the middle of the web page.)

- Activity: Take a GEOMETRY WALK through the school and/or outdoors. Use a digital camera to record the geometric objects you see. For a sample of results, watch this presentation from a class of 6th graders: TeacherTube Videos - Geometry Walk Geometry in the Real World
2. Correctly name shapes regardless of their orientations or overall size.
- Lesson: Tri-Straws Students will construct a triangle using various materials and explain why the shape is or is not a triangle.
- Resource: Triangle Paper Quilts
- Literature connection: Selina and the Bear Paw Quilt
3. Identify shapes as two-dimensional (lying in a plane, “flat”) or threedimensional
(“solid”).
Analyze, compare, create, and compose shapes.
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).
5. Model shapes in the world by building shapes from components (e.g.,
sticks and clay balls) and drawing shapes.
6. Compose simple shapes to form larger shapes. For example, “Can you
join these two triangles with full sides touching to make a rectangle?”

In Seven-Minute Boogie, students roll two dice, make a multiplication problem out of the numbers, write it down (with the answer), and repeat the process as many times as they can in seven minutes. Their score for the day is the number of multiplication sentences they got right in the seven minutes. The next day, they try to improve their scores. With regular dice, they practice low numbers, which are the most useful facts anyway. But you can alter dice to cover more facts: try "2-3-4-6-7-8" and "3-5-6-7-8-9," which miss only a few of the non-trivial facts." http://www.learner.org/channel/workshops/math/work_5.html
