What’s in each hub
Worksheet builder
Filter the published unit problems by unit, topic, difficulty or calculator use. Reorder, shuffle and print with an answer key on its own page.
Exit tickets
Pick up to three problems. Students rate their confidence and name one thing they are unsure about. Print two per page or share a link.
Present mode
Project one problem at a time in large type, with a timer and an answer you reveal when you are ready.
Shareable links
A link carries only the list of problems. No accounts, and students’ work stays on their own devices.
Misconceptions
Common wrong ideas for each topic, with the feedback that helps students correct them.
Standards alignment
Every problem is tagged with its course learning objectives, and every course links to its full outline.
