✨Kindergarten Math focuses on:
developing number sense, basic operations, spatial reasoning, and understanding simple patterns and measurements. The goal is to build a strong foundation in early math concepts through hands-on activities, visual models, and everyday experiences.
1. Counting and Cardinality (CC)
Detailed Topics:
-
Count to 100 by ones and tens, starting from any number.
-
Understand the relationship between numbers and quantities:
Recognize that the last number counted tells “how many” (cardinality).
-
Count objects up to 20, understanding one-to-one correspondence.
-
Compare numbers using terms like more, less, equal, greater than, less than.
-
Understand that numbers represent quantities and can be put in order.
2. Operations and Algebraic Thinking (OA)
Detailed Topics:
-
Understand addition as putting together and adding to, and subtraction as taking apart and taking from.
-
Use addition and subtraction within 10 to solve word problems with objects or drawings.
-
Decompose numbers less than or equal to 10 into pairs (e.g., 5 = 2 + 3).
-
Find the number that makes 10 when added to a given number.
-
Fluently add and subtract within 5.
3. Number and Operations in Base Ten (NBT)
Detailed Topics:
-
Work with numbers 11–19 to understand place value:
-
Recognize that these numbers are composed of ten ones and some more ones.
-
-
Use concrete models (e.g., base ten blocks) to represent these numbers.
4. Measurement and Data (MD)
Detailed Topics:
-
Describe and compare measurable attributes like length, weight, and capacity (longer/shorter, heavier/lighter).
-
Classify objects and count the number of objects in categories (sorting and categorizing).
-
Describe the categories by count (e.g., “There are 3 red blocks”).
5. Geometry (G)
Detailed Topics:
-
Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, spheres).
-
Analyze, compare, create, and compose shapes.
-
Combine simple shapes to form larger shapes (e.g., two triangles make a square).
-
Understand positional words such as above, below, beside, in front of, behind, and next to.
