# Kindergarten Math

## Unit 1: Operations and Algebraic Thinking

### April 6-17

• K.OA.1 Represent addition and subtraction using objects, fingers, pennies, drawings, sounds, acting out situations, verbal explanations, expressions, equations or other strategies.
• NY-K.OA.2a Add and subtract within 10.

## Unit 2: Numbers and Operations in Base Ten

### April 20-May 1

Work with numbers 11–19 to gain foundations for place value.

• K.NBT.1 Compose and decompose the numbers from 11 to 19 into ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

## Unit 3: Counting and Cardinality

### May 4-15

Know number names and the count sequence.

• NY-K.CC.1 Count to 100 by ones and by tens.
• NY-K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20

Count to tell the number of objects.

• NY-K.CC.4 Understand the relationship between numbers and quantities up to 20; connect counting to cardinality.

## Unit 4: Counting and Cardinality

### May 18-29

Count to tell the number of objects.

• NY-K.CC.5a Answer counting questions using as many as 20 objects arranged in a line, a rectangular array, and a circle. Answer counting questions using as many as 10 objects in a scattered configuration.

Compare numbers.

• NY-K.CC.6 Identify whether the number of objects in one group is greater than (more than), less than (fewer than), or equal to (the same as) the number of objects in another group.

## Unit 5: Measurement and Data

### June 1-5

Describe and compare measurable attributes.

NY-K.MD.1 Describe measurable attributes of an object(s), such as length or weight, using appropriate vocabulary. e.g., small, big, short, tall, empty, full, heavy, and light.

Classify objects and count the number of objects in each category.

NY-K.MD.3. Classify objects into given categories; count the objects in each category and sort the categories Note: Limit category counts to be less than or equal to 10.

NY-K.MD.4 Explore coins (pennies, nickels, dimes, and quarters) and begin identifying pennies and dimes.

## Unit 6: Geometry

### June 8-19

Analyze, compare, sort, and compose shapes.

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

NY-K-G.5 Model objects in their environment by building and/or drawing shapes.

NY-K-G.6 Compose larger shapes from simple shapes.
e.g., join two triangles to make a rectangle
