Working toward the goals of the Essential Learnings in mathematics, each third grader will understand concepts and apply procedures in the following areas:

Number Sense:

• Explores and represents whole numbers up to 100,000 and fractions (1/2-1/10).
• Adds and subtracts whole numbers up to 100,000 and decimals (money).
• Knows multiplication facts (0-9); expands multiplication to 3-digit number by 1-digit number; and multiples by power of 10.
• Explores the concept of division and relationship between multiplication and division.
• Compares, sequences and orders numbers up to 100,000.
• Selects and uses tools appropriately.
• Estimates and determines reasonableness of results.
• Develops, analyzes , and explains procedures for computation.
• Understands the relationships between numbers, number systems and symbols. 

Measurement:

• Expands estimates and measures to include perimeter, area and volume.
• Makes change for a varied amount of money.
• Tells time to the nearest minute.
• Uses calendar and clock to measure elapsed time
• Uses estimates to predict reasonableness of measurement.
• Expands measurement and comparison of characteristics of objects.
• Selects and uses appropriate tools for measurement.

Spatial Sense:

• Copies and constructs 2 and 3-dimensional shapes (plane and space).
• Demonstrates location of objects by using directional words.
• Expands symmetry and similarity of geometric objects.
• Explores parallel and perpendicular lines and congruency.
• Creates geometric shapes using manipulatives. 

Probability and Statistics:

• Recognizes difference between certain and uncertain events.
• Conducts experiments.
• Successfully collects, organizes, records, and graphs data using numerical and
  pictorial symbols.
• Expands the use of median and mode and introduces mean to describe data.
• Makes simple inferences from charts and graphs.
• Predicts outcomes of simple activities and compares the predictions to results of
  experiments.

Functions & Relationships:

• recognizes and creates patterns of objects and numbers.
• practices using guess and check in the search for patterns.
• represents number patterns using manipulatives and symbols.
• uses standard notation to read and write number sentences.
• solves simple equations at the concrete level.
