CA- California K-12 Academic Content Standards
Subject: Mathematics
Grade: Grade ThreeBy the end of grade three, students deepen their understanding of place value and their understanding of and skill with addition, subtraction, multiplication, and division of whole numbers. Students estimate, measure, and describe objects in space. They use patterns to help solve problems. They represent number rela-tionships and conduct simple probability experiments.
Area: Number Sense
Sub-Strand 1.0: Students understand the place value of whole numbers:
Standard 1.1: Count, read, and write whole numbers to 10,000.
Standard 1.2: Compare and order whole numbers to 10,000.
Standard 1.3 (Key Standard): Identify the place value for each digit in numbers to 10,000.
Standard 1.4: Round off numbers to 10,000 to the nearest ten, hundred, and thousand.
Standard 1.5 (Key Standard): Use expanded notation to represent numbers (e.g., 3,206 = 3,000 + 200 + 6).
Sub-Strand 2.0: Students calculate and solve problems involving addition, subtraction, multiplication, and division:
Standard 2.1 (Key Standard): Find the sum or difference of two whole numbers between 0 and 10,000.
Standard 2.2 (Key Standard): Memorize to automaticity the multiplication table for numbers between 1 and 10.
Standard 2.3 (Key Standard): Use the inverse relationship of multiplication and division to compute and check results.
Standard 2.4 (Key Standard): Solve simple problems involving multiplication of multidigit numbers by one-digit numbers (3,671 / 3 = __).
Standard 2.5: Solve division problems in which a multidigit number is evenly divided by a one-digit number (135 / 5 = __).
Standard 2.6: Understand the special properties of 0 and 1 in multiplication and division.
Standard 2.7: Determine the unit cost when given the total cost and number of units.
Standard 2.8: Solve problems that require two or more of the skills mentioned above.
Sub-Strand 3.0: Students understand the relationship between whole numbers, simple fractions, and decimals:
Standard 3.1: Compare fractions represented by drawings or concrete materials to show equivalency and to add and subtract simple fractions in context (e.g., 1 ⁄2 of a pizza is the same amount as 2 ⁄4 of another pizza that is the same size; show that 3 ⁄8 is larger than 1 ⁄4).
Standard 3.2 (Key Standard): Add and subtract simple fractions (e.g., determine that 1 ⁄8 + 3 ⁄8 is the same as 1 ⁄2).
Standard 3.3 (Key Standard): Solve problems involving addition, subtraction, multiplication, and division of money amounts in decimal notation and multiply and divide money amounts in decimal notation by using whole-number multipliers and divisors.
Standard 3.4: Know and understand that fractions and decimals are two different representations of the same concept (e.g., 50 cents is 1 ⁄2 of a dollar, 75 cents is 3 ⁄4 of a dollar).
Area: Algebra and Functions
Sub-Strand 1.0 : Students select appropriate symbols, operations, and properties to represent, describe, simplify, and solve simple number relationships:
Standard 1.1 (Key Standard): Represent relationships of quantities in the form of mathematical expressions, equations, or inequalities.
Standard 1.2: Solve problems involving numeric equations or inequalities.
Standard 1.3: Select appropriate operational and relational symbols to make an expression true (e.g., if 4 __ 3 = 12, what operational symbol goes in the blank?).
Standard 1.4: Express simple unit conversions in symbolic form (e.g., __ inches = __ feet ยด 12).
Standard 1.5: Recognize and use the commutative and associative properties of multiplication (e.g., if 5 x 7 = 35, then what is 7 x 5? and if 5 x 7 x 3 = 105, then what is 7 x 3 x 5?).
Sub-Strand 2.0: Students represent simple functional relationships:
Standard 2.1 (Key Standard): Solve simple problems involving a functional relationship between two quantities (e.g., find the total cost of multiple items given the cost per unit).
Standard 2.2: Extend and recognize a linear pattern by its rules (e.g., the number of legs on a given number of horses may be calculated by counting by 4s or by multiplying the number of horses by 4).
Area: Measurement and Geometry
Sub-Strand 1.0: Students choose and use appropriate units and measurement tools to quantify the properties of objects:
Standard 1.1: Choose the appropriate tools and units (metric and U.S.) and estimate and measure the length, liquid volume, and weight/mass of given objects.
Standard 1.2 (Key Standard): Estimate or determine the area and volume of solid figures by covering them with squares or by counting the number of cubes that would fill them.
Standard 1.3 (Key Standard): Find the perimeter of a polygon with integer sides.
Standard 1.4: Carry out simple unit conversions within a system of measurement (e.g., centime-ters and meters, hours and minutes).
Sub-Strand 2.0: Students describe and compare the attributes of plane and solid geometric figures and use their understanding to show relationships and solve problems:
Standard 2.1 (Key Standard): Identify, describe, and classify polygons (including pentagons, hexagons, and octagons).
Standard 2.2 (Key Standard): Identify attributes of triangles (e.g., two equal sides for the isosceles triangle, three equal sides for the equilateral triangle, right angle for the right triangle).
Standard 2.3 (Key Standard): Identify attributes of quadrilaterals (e.g., parallel sides for the parallelogram, right angles for the rectangle, equal sides and right angles for the square).
Standard 2.4: Identify right angles in geometric figures or in appropriate objects and determine whether other angles are greater or less than a right angle.
Standard 2.5: Identify, describe, and classify common three-dimensional geometric objects (e.g., cube, rectangular solid, sphere, prism, pyramid, cone, cylinder).
Standard 2.6: Identify common solid objects that are the components needed to make a more complex solid object.
Area: Mathematical Reasoning
Sub-Strand 2.0: Students use strategies, skills, and concepts in finding solutions:
Standard 2.1: Use estimation to verify the reasonableness of calculated results.
Standard 2.2: Apply strategies and results from simpler problems to more complex problems.
Standard 2.3: Use a variety of methods, such as words, numbers, symbols, charts, graphs, tables, diagrams, and models, to explain mathematical reasoning.
Standard 2.4: Express the solution clearly and logically by using the appropriate mathematical notation and terms and clear language; support solutions with evidence in both verbal and symbolic work.
Standard 2.5: Indicate the relative advantages of exact and approximate solutions to problems and give answers to a specified degree of accuracy.
Standard 2.6: Make precise calculations and check the validity of the results from the context of the problem.
