Grade 4 Math: Operations, Fractions, Decimals & Geometry

This complete Grade 4 math curriculum includes 46 interactive lessons that guide learners from place value to geometry. The course emphasizes conceptual understanding and efficient problem solving through visual models, guided practice, and real-world applications. Learners begin with place value and number sense, including reading, writing, comparing, rounding, and identifying number patterns. Core focus areas are multi-digit addition and subtraction and multi-digit multiplication and division. Students explore these operations using place value models, area models, partial products, partial quotients, and standard methods to build flexible strategies and procedural fluency. Number theory topics include factors, multiples, and classifying prime and composite numbers. The curriculum then develops a deep understanding of fractions: generating equivalent fractions, comparing and ordering fractions, adding and subtracting fractions and mixed numbers with like denominators, and multiplying fractions by whole numbers. Students connect fractions to decimals, learn decimal place value, and compare and add values represented as decimals. Measurement units, conversions within the same system, perimeter and area problem solving, and real-world measurement tasks are included. Geometry instruction covers lines, rays, segments, angle measurement and construction, classification of triangles and quadrilaterals, symmetry, and geometric pattern analysis. Each lesson reinforces prior skills with practice, math games, and opportunities to explain reasoning and choose efficient strategies. The course is suitable for Grade 4 learners and families seeking a structured, standards-aligned sequence of lessons taught in an interactive online classroom.
