Welcome
Welcome to Sparebrain Bazaar, a collection of free, high-quality educational tools and resources designed to support educators and learners across diverse disciplines.
This is a space where teaching, technology, and creativity intersect—offering practical solutions that help educators teach more effectively and students learn more deeply.
About the Project
With over 20 years of experience teaching at the graduate and professional level, and an equal amount of time building educational technology, Sparebrain projects are designed with one core principle: cost should never be a barrier to quality education.
The mission is simple: Create accessible, user-friendly tools that solve real problems for teachers and learners—and share them freely so everyone can benefit.
All resources here are built through hands-on work with students, trainees, and educators. Each tool is designed to help users understand complex ideas, think critically, and apply knowledge in meaningful ways.
Tools & Projects
These tools are free to use—no account, no paywall, no strings attached.
Generate customizable, printable arithmetic worksheets for students. Choose from addition, subtraction, multiplication, and division; set difficulty ranges; control problem count and layout; and toggle answers on or off. Designed for teachers, parents, and homeschoolers.
Open SumTodo →A Chrome extension that fills in the repetitive fields of CE Broker's “Report CE” wizard, so logging a continuing-education credit takes a few clicks instead of retyping the same answers every time. Save your provider, accreditation statement, course type, and hours once, and CE Relay enters them as you move through the steps. It fills; it never submits—every page is left for you to review and continue yourself.
Privacy by design: the only permission it requests is local storage for your own settings. It runs on the Report CE pages of secure.cebroker.com and nowhere else, makes no network requests of its own, and collects, transmits, and tracks nothing.
CE Relay is an independent tool and is not affiliated with, endorsed by, or sponsored by CE Broker or Propelus.
Coming soon to the Chrome Web Store
A Chrome extension that turns a Canvas discussion board into a clean, printable page. Click the toolbar icon on any discussion and it rebuilds the thread as colour-coded cards—each with the poster's name, avatar, date and full post—then prints or saves to PDF with the discussion title already set as the filename. Long threads export in full, including replies Canvas hasn't yet loaded onto the page.
Privacy by design: it does nothing until you click it, asks for no standing access to your browsing, and sends nothing to Sparebrain. The discussion it reads stays in your browser and is discarded when you close the tab. Works with Canvas at any institution, including schools on a custom domain and self-hosted installations.
Discussion Export for Canvas is an independent tool and is not affiliated with, endorsed by, or sponsored by Instructure, Inc.
