Math Teacher Resources

Need elementary math resources? Use Lesson Planet to find curriculum covering topics such as counting, shapes (like this shape-dice printable!), addition, subtraction, time (this time concept book is fantastic), measurement, and arithmetic. Try this interactive to help youngsters understand the relationship between addition and subtraction. 

For more advanced classes, find lessons on geometry, fractions, percent, ratios, rates, proportions (here's a great video), area (simple worksheet here), volume, triangles, angles, exponents, negative numbers, statistics and probability, linear equations, graphing, real-world problem solving, polynomials, trigonometry, and matrices. Even find resources for more advanced topics such as series, limits, and derivatives covered in calculus and pre-calculus courses.

Whether you are teaching the basics or advanced topics, Lesson Planet can guide you to resources that will make math come alive for students!
