Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

What better way to introduce the idea of a sequence than with robots! An educational lesson explains the classic Fibonacci sequence before pupils build and program a robot to move. Additionally, the lesson challenges individuals to...

Seventh grade math is so much fun! They solve 10 different problems that include using patterns to complete a table, describe the pattern, and identify the specific term in the pattern for each. Then they give a description of the...

Fe, phi, fo, fum. This activity leads pairs to find the ratio of consecutive terms of the Fibonacci sequence. The pairs find that the Fibonacci sequence can be found in many places. A discussion with the class shows that the ratios...

High Schoolers use the TI-83 calculator to produce a sequence, explore patterns and find a linear or quadratic equation for a given pattern. They use inductive reasoning to make conjectures about patterns. They find the Y-value of a...

Given the first few terms in an arithmetic sequence, find the next term in the sequence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Given the formula of an arithmetic sequence, either in explicit form or in recursive form, find a specific term in the sequence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

Given the formula of a geometric sequence, either in explicit form or in recursive form, find a specific term in the sequence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

In addition to arithmetic and geometric sequences, Fibonacci Numbers, and figurate numbers, there are countless interesting sequences that don't follow a similar, regular pattern. These include prime numbers, perfect numbers, the...

There are many other sequences that are based on certain geometric shapes. These sequences are often called Figurate numbers, numbers that can be represented using geometric shapes. Examples include square, triangle, and tetrahedral...

This lesson focuses on arithmetic and geometric sequences using several examples and practice exercises.

Explore this course in sequences and patterns including simple sequence, triangle and square numbers, terms, recursive formulas, and explicit formulas. Click on Trailer on the top left to watch an introductory video.
