Here’s a summary of the California Common Core State Standards for Mathematics for 1st to 3rd graders, organized by key mathematical concepts:

1st Grade:

1. Operations and Algebraic Thinking:

• Add and subtract within 20 (e.g., 9 + 7 = 16, 15 - 8 = 7).

• Solve word problems involving addition and subtraction.

• Understand the properties of operations (e.g., the commutative property of addition).

• Work with addition and subtraction equations (e.g., 8 + ? = 12).

2. Number and Operations in Base Ten:

• Understand place value (ones, tens).

• Count to 120 starting at any number.

• Add and subtract within 100 using strategies based on place value.

3. Measurement and Data:

• Measure lengths using non-standard units (e.g., paper clips, blocks).

• Tell and write time (hour and half-hour).

• Represent and interpret data (e.g., picture graphs, bar graphs).

4. Geometry:

• Reason with shapes and their attributes.

• Classify and sort 2D and 3D shapes based on their attributes (e.g., number of sides or vertices).

2nd Grade:

1. Operations and Algebraic Thinking:

• Add and subtract within 100.

• Solve word problems with addition and subtraction, involving lengths and measurements.

• Work with basic facts for multiplication and division (introduce the concept of repeated addition).

2. Number and Operations in Base Ten:

• Understand place value up to 100 (ones, tens, and hundreds).

• Add and subtract within 1,000 using place value strategies.

• Skip count by twos, fives, and tens (up to 100).

3. Measurement and Data:

• Measure and estimate lengths using appropriate units (e.g., inches, centimeters).

• Tell time to the nearest five minutes.

• Represent and interpret data using line plots, bar graphs, and tally charts.

• Solve simple addition and subtraction problems using coins (money).

4. Geometry:

• Recognize and draw shapes with specified attributes.

• Partition circles and rectangles into two, three, or four equal parts and understand the concept of fractions (1/2, 1/3, 1/4).

3rd Grade:

1. Operations and Algebraic Thinking:

• Multiply and divide within 100 (basic multiplication tables, simple division).

• Solve multi-step word problems involving all four operations.

• Understand the relationship between multiplication and division.

2. Number and Operations in Base Ten:

• Understand place value up to 1,000.

• Round numbers to the nearest ten or hundred.

• Add and subtract within 1,000, including using mental math and estimation strategies.

3. Measurement and Data:

• Solve problems involving time, liquid volume, and mass (e.g., measuring lengths, weighing objects, calculating elapsed time).

• Represent and interpret data using bar graphs, pictographs, and line plots.

• Understand and measure angles (e.g., right angles, acute and obtuse).

4. Geometry:

• Understand shapes and their properties (e.g., quadrilaterals, triangles).

• Partition shapes into equal parts and express the parts as fractions.

• Classify 2D shapes (triangles, quadrilaterals, polygons) based on attributes.
