Equivalent Fractions Notes: Visuals and Standard Algorithm - Printable
These Fraction Notes were designed for use with middle school students, but can also be used with upper elementary or low performing high school students. This also provides great scaffolding for special education students. These notes allow students to draw visuals of fractions, create equivalent fracitions using a visual, and create equivalent fractions using multiplication and division.

Subtraction Algorithms for all grades
This file contains the notes I took at the NCTM Conference in Chicago. I attended a presentation on Subtraction by Frances Stern. She taught various ways to subtract with regrouping. My most favorite to use in class is the number line and France's way on pages 6-7. The France way is what I refer to in my class as "Give, Give It Back"...It's SO MUCH EASIER TO TEACH AND UNDERSTAND than the Traditional U.S. way. I don't know where this has been all my life. Please give it a try! It takes some pract

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

Root Finding Algorithms - Numerical Methods - First few pages
This is the chapter on Root Finding Algorithms from a larger project I wrote: A Numerical Methods Companion for High School Mathematics, which intended to be an aid for teachers of 10th, 11th, and 12th grade math to introduce computer science concepts in a manner which parallels topics taught in a standard math curriculum. Included in this PDF are the first few pages of a chapter that gives explanations for many root finding algorithms, including Bisection Method, Newton Method, and Secant Met

Date of Easter Calculator
In this learning packet, students work through an algorithm that leads them to predict the month and day of Easter for any year (from 1583 onwards). Because the date of Easter is tied to the movement of the moon and earth around the sun, it can be predicted mathematically. This packet contains teacher notes, references, and an answer key (calculations necessary to predict the month/day of Easter for 2013). This packet would be appropriate for earth science, astronomy, or applied math classes

Lattice Multiplication Grid Blank 2 by 1
Do you have students who struggle with the standard algorithm of multiplication? Well using blank lattice grids for multiplication offers a hands-on, visual approach that helps students understand the multiplication process step-by-step. This method breaks down the problem into smaller, manageable parts, reinforcing place value and partial products. It encourages accuracy and organization while building students’ confidence with multi-digit multiplication. The blank grids also promote student en

This exercise focuses on using the “Complete the Square” method to calculate the Real Roots so it only makes sense to use a Quadratic Function that has two real roots. We start with a Quadratic Function defined as −3∗x2+2∗x+4

Solving for the nth Term in Quadratics Using a Chart Technique
This is a way for student to find the nth term of a quadratic using a systematic algorithm that they usually find (not only) less complicated than guess and check, but also fun. Many feel that it feels like they are solving a puzzle. They find first and second differences through a chart they fill in, and then create a second chart to use their findings and actually formulate the nth term statement.

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
