Place Value, Parts, and Space: Grade 5 Mathematics

Grade 5 · 317 pages · 72 lessons · PDF, print at home

A full-year grade 5 mathematics course built on three connected stories: how our place-value system extends to decimals and governs all arithmetic, how fractions behave as amounts that can be combined and split, and how measurement and space (volume, the coordinate plane, patterns) let us model the world. Every new procedure is introduced with an area model, number line, or fraction bar before any symbolic algorithm. Units are sequenced so each new topic depends on a named skill from the one before, with cumulative retrieval built into every unit after the first. Aligned to CCSS grade 5 mathematics.
