Using the app

Share a graph or make a match-the-graph challenge

Send a graph as a link or QR code, and make challenges where students type equations to match a hidden graph.

Open in Trident

A share link holds the whole graph, so nothing is uploaded and nobody needs an account. Anyone who opens the link gets their own copy.

1. Tap the Share button in the top bar. Tap Copy link, or Share… to send it with another app.
2. Show the QR code on the board; students scan it with their camera to open the graph.
3. To make a challenge, build the graph students should match, then open Menu › Make a challenge.
4. Tick the lines students must match and add instructions if you like, then tap Make the challenge. The share sheet opens with the challenge link.
5. Students see a dashed graph with its equation hidden. When their own line lands on top of it, the banner says "Matched!" and the line gets a check mark.
6. Built-in practice challenges are in the light bulb sheet under Match the graph.

Tips

• Challenges compare the pictures, not the algebra, so y = 2(x + 1) matches y = 2x + 2.
• The answer travels inside the link, so use challenges for practice rather than grades.
• Very large graphs are too long for a QR code; share the link instead.
