Euclid's Algorithm - uses in a high school mathematics class
Euclid’s Algorithm (EA) is a simple process by which you can find out the greatest common factor (GCF) of two numbers by repeatedly subtracting the smaller number from the bigger one. Euclid proved and used it in his series of textbooks, called the ‘Elements’.
On my first practicum, I was distraught to find that when I was teaching factorisation by common factor to my year 10s, many of them couldn’t remember their times tables. I couldn’t find any method of getting them to find the GCF between

Cosmo's Minus Method (Poster / Handout)
Cosmo's Minus Method is an adaptation of Cramer's Rule I made for my Algebra 2 class. I wanted them to have this algorithm as an alternative to substitution or elimination to solve moderately difficult systems of 2 linear equations in standard form. I chose not to call it Cramer's Rule because a quick google search would reveal how to use Cramer's Rule with the available TI-84 Graphing Calculators. Also, the title of the algorithm "Cosmo's Minus Method" comes from the name of the crazy neighbor
