Math 4

Building Strength for Complex Thinking (Ages 9–11). Math 4 is built around depth, not speed. Over 36 weeks, students work through advanced 4th grade concepts; multiplication, division, fractions, geometry, logic, and number theory, using Beast Academy’s puzzle-driven curriculum. This is for students who are ready to stop following steps and start understanding why they work.

Course Overview

This class is not for every child.

Math 4 is for advanced 4th graders ages 9–11 who are ready to stop following steps and start understanding why they work.

Knows multiplication but doesn’t know why it works.

Math 4 asks why, every session. Students explore the structure of multiplication, the logic of divisibility, and the patterns that turn arithmetic into number theory.

Fractions are still confusing — especially operations.

Math 4 builds fraction understanding the right way: models and meaning before algorithms. Students who have been memorizing rules often have a breakthrough here.

Can find perimeter but doesn’t really understand angles.

Geometry in Math 4 goes beyond shapes — students measure, classify, and reason about angles, symmetry, and coordinate planes, building the spatial intuition 5th and 6th grade demands.

Ready for competitions and advanced math.

The problem-solving strategies introduced here — working backwards, casework, invariants — are the foundation of AMC 8, MATHCOUNTS, and competition math at every level beyond.

Exponents

Understanding powers and exponents. Perfect squares. Exponent notation and evaluation. Applying exponents to place value and powers of 10. Introduction to scientific notation. (4.NBT.A.1, 6.EE.A.1)

Perimeter & Area

Perimeter of polygons. Area of rectangles using multiplication. Area of complex shapes by decomposing into rectangles. Missing side lengths. Same perimeter/different area problems. (4.MD.A.3, 3.MD.C.7, 3.MD.D.8)

Division

Multi-digit division with understanding. Interpreting remainders in context. Division as the inverse of multiplication. Divisibility rules and why they work. Long division strategies. (4.NBT.B.6, 4.OA.A.2, 4.OA.A.3, 4.OA.B.4)

Logic

Logical reasoning and deduction. Venn diagrams and set relationships. If-then reasoning. Logic puzzles. Applying logical structure to multi-step math problems. (MP.2, MP.3, MP.6)

Probability

Probability as a measure of likelihood. Simple probability experiments. Equally likely outcomes. Theoretical vs. experimental probability. Using fractions to express probability. (7.SP.C.5, 7.SP.C.6)

Symmetry

Lines of symmetry in 2D shapes. Reflective and rotational symmetry. Creating and completing symmetric figures. Symmetry in regular polygons. (4.G.A.3)

Mid-Year Exam

A timed, written assessment covering all Session 1 topics. Students solve multi-step problems that require applying not just recalling what they’ve learned. Results help identify strengths and areas to focus on in Session 2.

Detailed Curriculum — Session 2
