The Real Numbers: Size of Infinite Sets
The learning opportunities with the resource on infinity are finite, but it's still good to use. Individuals investigate the size of the set of integers and the set of even integers. Conclusion: the two sets have the same size.

Arithmetic and Geometric Sequences
Old mathematicians never die; they just lose some of their functions. Studying sequences gives scholars an opportunity to use a new notation. Learners write functions to model arithmetic and geometric sequences and use them to find new...
Curated OER
Converge or Diverge?
Students prepare for the calculus concepts of limits by examining sequences that converge and diverge. By using an Excel program that generates sequences, students manipulate the starting number, multiplier and add-on values, and examine...

Units Multiplication Closure Activity
Students practice multiplication. In this multiplication lesson, students multiply two numbers and closely examine how multiplication affects the units digit of the product.
Curated OER
Jazz and Math: Improvisation Permutations
Learners explore the various rhythmic combinations in jazz and blues music. They watch a video segment, apply a mathematical formula to calculate the number of possible rhythmic combinations, and perform a combination of notes and...
