Start from the grade
Choose one skill below after checking the homework unit or the student's explanation. Each topic page then focuses on that single concept, its visual model, common mistakes, and a short mission sequence.
Grade 4 deepens arithmetic and introduces number theory. Students learn the standard multi-digit multiplication and long-division algorithms via the area model and place-value sharing, find factor pairs and classify numbers as prime or composite, work with like-denominator fractions and mixed numbers, translate decimals to/from fractions, and measure and compose angles with a protractor. All 4th grade games run free online β no Flash, no downloads, and no accounts to manage.
Grade Mastery Map
Grade 4 should turn procedures into explainable strategies. Students extend multi-digit multiplication and long division, analyze factors and primes, compare fractions, connect fractions to decimals, and measure angles, symmetry, and unit conversions.

Problems This Page Solves
Stepper-style missions expose each estimate, subtraction, and remainder so the algorithm is explainable.
Students reason about denominators, common units, and equivalent values instead of choosing the larger-looking number.
Angle and symmetry missions attach terms to actions students perform, not just definitions they read.
Recommended Learning Route
Multi-digit multiplication, long division, factors, and primes anchor the number work for Grade 4.
Fraction comparison, fraction operations, and decimal notation become related representations.
Angles, angle sums, geometry, symmetry, and unit conversion turn visual reasoning into precise language.
