✏️ Math Modules from Khan Academy. Khan Academy offers a wealth of free math educational resources, including a large library of instructional videos and online practice problem sets. – All

Tip – On Khan Academy, the Pre-Algebra modules are divided by grade. Grade 5 introduces the use of parentheses in numerical expressions, establishing relationships between sets of two variables (ordered pairs), and working in the coordinate plane. Grade 6 covers algebraic concepts across two modules: Variables & expressions and Equations & inequalities.

equations & expressions

📖 Mystery Math: A First Book of Algebra by David Adler. This picture book introduction to the concepts of forming and solving algebraic equations will nicely supplement your child's first forays into elementary algebra. – Elementary

✏️ Equality Explorer – Basics from PhET. “Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with objects on a balance. Find all the ways to balance cats and dogs or apples and oranges.” – Elementary • Middle

✏️ Equality Explorer – Two Variables from PhET. “Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with integers and variables on a balance. Find multiple ways to balance x and y to build a system of equations.” – Middle

✏️ Equality Explorer – Expression Exchange from PhET. “Build coin expressions, then exchange them for variable expressions. Simplify and evaluate expressions until you are ready to test your understanding of equivalent expressions in the game!” – Elementary • Middle

✏️ Function Builder from PhET. “Play with functions while you ponder Art History. Explore geometric transformations and transform your thinking about linear functions, then have fun figuring out the mystery functions!” – Elementary • Middle

order of operations

✏️ Order of Operations from CK12. CK12 offers free, adaptive online practice across all areas of math. Practice working with order of operations in this module. – Elementary • Middle

▶️ How to defeat a dragon with math from TED-Ed. “Having trouble remembering the order of operations? Let's raise the stakes a little bit. What if the future of your (theoretical) kingdom depended on it? Garth Sundem creates a world in which PEMDAS is the hero but only heroic when in the proper order.” – Elementary • Middle

graphing & coordinate plane

📖 A Fly on the Ceiling by Julie Glass. This Step-Into-Reading title is a nice addition to a study of coordinate graphs. "Recognized as the father of analytic geometry, René Descartes was a French mathematician and philosopher. Kids will love this funny and very accessible tale, based on one of math's greatest myths, about the man who popularized the Cartesian system of coordinates." – Elementary

✋Dry-erase graphing mats. A dry erase mat (or board) printed with a coordinate grid and and x-y axis can be a real timesaver when studying graphing in the coordinate plane. The linked product is for a set of 10 reusable graphing mats sold by Learning Resources. – All

✏️ Graphing Lines from PhET. “Explore the world of lines. Investigate the relationships between linear equations, slope, and graphs of lines. Challenge yourself in the line game!” – Elementary • Middle
