Level 3
Mathematics text and practise book for you and your learners
Key Concepts of Intermediate Level Math is an open textbook that efficiently covers a review of foundational mathematics up to the end of high school. The author states it can be used by new teachers to brush up on their math, parents to help their children with homework and adult basic education students with some past math experience.
Pre-GED adult education math and numeracy slides
Literacy Minnesota produced a series of math lessons for remote learning situations. Explanatory information on slides accompanies the math textbook/workbook, Math Sense 2. However the slides can work with any resource, online or on paper, that provides an opportunity to practise the concepts and strategies introduced in the slides. A teacher guide and lesson template are also available. Pre-GED or Math 2 "applies basic numeracy skills to proportional reasoning, pre-algebra and geometry. The lessons in these units can help students learn, review or improve their skills in preparation for the GED, the Accuplacer, or for certain careers."

Open online math textbook
The NROC project, a non-profit that collaborates with secondary, postsecondary and adult education leaders, has developed an open developmental math program that is web-based.
Here are the contents (PDF).
GED math videos
The Florida Literacy Coalition has curated a collection of Khan Academy video mini-lessons to help adult learners prepare to write the math portion of the GED test. There are six topics in the collection:
Foundations
Basic math
Basic algebra
Graphs and functions
Geometry
Each topic has a pre and post test using Google Forms. The videos and quizzes can be accessed on a website or an app. A fillable PDF tracking sheet is also available.
Khan Academy content is free and can be downloaded. It can also be re-posted on other sites. Uses are limited to non-commercial, educational purposes.
GED math packets
While this collection of GED and high school equivalency math packets (PDFs) is aligned to New York state requirements. Topics are similar to the Canadian GED test but different from the new CAEC test.
These are the 8 subject areas, divided into part one and part two, for a total of 16 packets:
Geometry
Area & Population Density
Volume & the Density of Matter
Rigid Transformations: Shapes on a Plane
Lines, Angles, & Shapes: Measuring Our World
Algebra and Functions
The Power of Exponents
Tools of Algebra: Expressions, Equations, and Inequalities
Tools of Algebra: Linear Functions
Tools of Algebra: Nonlinear Functions

Math games and simulations
Open source math and science simulations
PhEt interactive is an open collection of online math and science simulations designed to help students understand fundamental concepts in math, physics, chemistry and biology. You can download, embed and sync the content to Google Classroom. Extensive teaching resources targeting use throughout K-12 are also available. In addition, a variety of translations are available, including French.

Math challenges and games
Tasks, games and problem-based activities from NRICH Maths at the University of Cambridge. Explore the following topics to find suitable activities:
They also have some additional interactive games developed for online use or whiteboards.
Activities are accompanied with an age range which will give you some indication of a GLE. They also indicate the difficulty with one, two or three stars. all challenges have an online explanation and accompanying printable.

Interpreting interesting graphs
Each week, a graph is posted for students to analyze in a feature called What's going on in this graph? Students can also post responses but will need an account. You can see all comments for the graph, which could be used as part of your instruction. After commenting closes, an explanation of the graph is also published. You can search the collection and access over 60 graphs along with the archived comments and explanation. In addition, teaching support is available using the On-Demand Webinar: Teaching With Graphs From The New York Times.

Slow reveal graphs
Slow reveal graphs are reverse engineered so students can discover and make sense of the data and processes involved in representing data. "It starts with a graph that has been stripped of context: its numbers, its labels, its title. The teacher facilitates a discussion around what students notice and wonder."
CollectEdNY also has an extensive collection.
Read an article from the Adult Numeracy Network‘s Math Practitioner (Summer 2022 issue), where an educator explains how he uses slow reveal graphs in his classroom and why the routine is so effective – Slow Reveal Graphs: A Powerful Instructional Routine.
