Third Grade Mathematics Content Standards
Third grade students are expected to:
-
Number and operations
- Use knowledge of place value to count, name, write, compare,
order and make quantities in hundreds and thousands
- identify place value of digits up to 10,000
- round to the nearest 1,000 and 10,000
- use expanded notation (3,000 + 200 + 6 = 3,206)
- Add and subtract two to five digit numbers, including regrouping
- Understand multiplication as repeated addition
- Solve problems with multi-digit numbers by one digit numbers (671 x 3 = 2,013)
- Instantly recall multiplication facts (1-10)
- Use multiplication in problem solving situations
- Find the solution to simple division problems by putting things
into groups and sharing equally
- solve problems when multi-digit numbers are evenly divided by one-digit numbers (135/5)
- Use inverse relationship of multiplication and division to compute and check results
- Round off and use exact numbers as appropriate in real life situations
- Find fractions (halves, thirds, fourths, eighths, tenths,
twelfths) of wholes
- compare fractions to show equivalency using drawings and concrete materials
- add and subtract simple fractions with like denominators
- Add, subtract, and multiply and divide money amounts
- know and understand the relationship of fractions and decimals as it relates to money (50 cents = 1/2 dollar)
- Use knowledge of place value to count, name, write, compare,
order and make quantities in hundreds and thousands
-
Geometry and measurement
- Understand the concepts of length, perimeter, area, volume, and
weight, using appropriate units when measuring
- find the perimeter of a polygon
- Complete unit conversions. e.g. inches to feet, minutes to hours, centimeters to meters
- Identify and describe and classify 3-dimensional objects
- Identify attributes of triangles and quadrilaterals (e.g. parallel lines; equal sides; right angles; isosceles, equilateral and right triangles)
- Identify right angles and angles less than and greater than right angles
- Use traditional clocks to tell time to the nearest minute and determine duration of time intervals
- Understand the concepts of length, perimeter, area, volume, and
weight, using appropriate units when measuring
-
Function and Algebra
- Use a function rule to solve simple problems and make
predictions (1 bike, 2 wheels;
2 bikes, 4 wheels)
Understand the relationship between two related objects and solve problems- use appropriate symbols, operations and properties (<, >, =, 5 x 7 = 7 x 5)
- Use symbols to stand for quantities
- Use a function rule to solve simple problems and make
predictions (1 bike, 2 wheels;
2 bikes, 4 wheels)
- Statistics and Probability
- Collect, organize, and display data
- Use data to determine the probability of an event
- Make simple inferences about real life data
- Predict outcome of simple probability events
-
Problem solving and math reasoning
- Use a variety of strategies, and approaches to solve problems
- Estimate and use context to verify reasonableness of answer
- Find logical solutions and clearly explain reasoning using words, numbers, symbols, pictures, charts, tables, diagrams, or models
- Analyze and apply strategies to solve problems that require students to add, subtract, multiply, and/or divide (e.g. apply simpler problems to more complex problems, generalize results and extend to other circumstances)
-
Math communication
- Use appropriate mathematical terms, vocabulary, and language
- Understand oral and written directions for appropriate mathematical activities
