Students in Grade 4 use mathematics to model real world situations.

• In Unit 1, students organize and display data in a variety of ways, including line plots, line graphs, and circle graphs. They analyze the appropriateness and inappropriateness of various data displays. Students determine the mean, median, mode, and range of data. Students explore, model, and identify place value in large numbers. In addition, student’s identify/classify/draw angles and describe how points, lines segments, rays, and angles are related.
• In Unit 2, students solve for an unknown, generalize a pattern by stating a rule, and complete a function table using a given rule. Students explore the commutative and associative properties. Students continue to develop proficiency with basic facts. Students find multiples and factors of numbers in order to help with mastery of multiplication and division fact families.
• In Unit 3, students study the relationship between fractions and decimals. Students recognize, name, compare, and order fractions and decimals. Students practice adding/subtracting fractions with like denominators and decimal fractions. Students use models and pictures to multiply a fraction by a whole number. In addition, students explore probability concepts.
• In Unit 4, students continue to develop proficiency with multiplication and division as it applies to two-or-three-digit factors. Students practice estimation and reasonableness of answers. Students examine equivalent periods of time and determine elapsed time.
• In Unit 5, students explore specific movements of objects to identify and describe transformations. Students estimate, measure, determine, and use formulas as it relates to perimeter, area, and volume to solve problems. Students are introduced to positive and negative numbers in concrete situations.
