A supplemental practice source, not a course. MathOtter doesn't replace what you do -- it can amplify your efforts.You can use it to assign practice problems on specific topics to individual students. It provides practice problems, answers, and step-by-step solutions to reinforce online or in-person instruction.
Built for struggling adult learners, particularly those preparing for GED math -- but it can be used by anyone seeking additional math practice.
Easy for students to use! The web app runs in the browser on nearly any device with a modern web browser. You can assign a set of problems for students to work on without any friction (no signup, ads, installation or personal information required).
No grading or progress tracking. Learners practice, check answers, and study the step-by-step solutions.
Founded on classroom experience. The topic choices reflect gaps seen firsthand while teaching. This includes common stumbling blocks: signed-integer arithmetic, fractions and decimals, for example.
What makes the content distinctive
Problem-specific scalable visuals. Plotted inequalities, linear function graphs, number lines, and geometric shapes are drawn for the actual problem -- not just generic illustrations.
Carefully curated "clean" numbers. System of equations solutions are integer points; quadratic formula problems have positive perfect-square discriminants. Students can focus on concepts instead of messy arithmetic.
Broad, deep coverage. More than 90 topics ("flashcards") spanning number sense, fractions, exponents and roots, mathematical reasoning, equations, linear functions, geometry, data analysis, and probability.
Wide range of problem volume. From about 30 hand-written word problems on some topics to millions of generated permutations on others.
Imbedded calculator emulator. For some key topics, an emulation of the TI-30XS is included. It steps the student through the key sequences for the exact problem they are working on.
