Segment A of Mathematics 4 teaches that proficiency with basic facts aids in the computation of numbers. Place value patterns are repeated in numbers, and symbol notation is used to represent mathematical relationships in numbers. Students will work with money to understand place value, refine skills with addition and subtraction, and practice multiplying with larger numbers. They will work with one-digit divisors in division problems. Students will compare and contrast measurement units, working with units of capacity and weight and the metric system.

Segment B covers fragments and decimals, teaching that a fraction describes the division of a whole into equal parts, and it can be interpreted in more than one way depending on the whole to be divided. Both common and decimal fractions can be represented using fractional parts. Students will also learn that reading, understanding, interpreting, and communicating data are critical in modeling a variety of real-world situations, drawing appropriate inferences, making informed decisions, and justifying those decisions. Spatial sense and geometric relationships are a means to solve problems and make sense of a variety of phenomenal. Real world situations can be represented symbolically and graphically.
