Arithmetic Series
Fall for a series. Learners determine how to find out how far a skydiver falls in the first 20 seconds. The Algebra II lesson introduces the idea of adding up the terms of an arithmetic sequence. Pupils learn how to use Sigma notation to...

Sums of Geometric Series
Geometric series either get bigger or approach a single number. So, how do you know which it is? An interactive presents three different geometric series with varying common ratios. With the aid of patterns, pupils determine values of r...
CK-12 Foundation
Sequence of Partial Sums: Partial Sums
Have some fun building squares out of triangles. Pupils investigate the partial sums of odd numbers. Using the sum of the first four odd numbers, learners see that it can be rewritten as a sum containing a triangular number. Simplifying...

Sum Notation and Properties of Sigma: Cracking the Code
Help your class develop an understanding of sigma notation. Pupils match the sigma notation with the sums. Using the expanded sums, learners evaluate the summations. The scholars move on to prove a property of sums.
Curated OER
Matrix Analysis of Networks
Explore the connection between a finite graph, a directed graph, and a matrix. Graph lines and identify the relationship of matrices in real-world scenarios. Then use this information to work with a partner to plan and design a...
Curated OER
Continuity and Limits
In this continuity and limits learning exercise, students solve and complete 4 different types of problems. First, they determine which of the limits shown exist and then, evaluate them. They also find which functions are continuous at a...
Curated OER
Autobiographical Art
Students explore how one artist portrays her own experiences and interests through her art. Students then choose themes in their own lives and create works of art inspired by those themes.
Curated OER
Dimension and Rank
Students determine the dimension of a subspace. For this dimension and rank lesson, students explore the dimension of a vector space. They compare and explore the relationship in a matrix.
Curated OER
Infinity and Cardinality
For this infinity worksheet, students determine a one-to-one correspondence between two finite sets. They discuss the relationship between the cardinalities. This one-page worksheet contains two problems.
Curated OER
Cardinality and Power Set
In this cardinality activity, students identify the cardinality of a finite set. This one-page activity contains eight problems.
