Check the choices
Edit the blue, red, green and yellow options, choose the correct colour, then drag questions into the order you want.
Present the check

BUILT FOR WHOLE-CLASS KNOWLEDGE CHECKS
One clear question, four diagnostic choices
The question and answers share one continuous presenter surface. Four large answer cards sit in a single blue, red, green and yellow row, ready for comparison and discussion.
QUESTION SLIDE
Give the class thinking time
The question and its two or four options remain visible until you choose to reveal the answer.
ANSWER SLIDE
Reveal without losing context
A large white tick stamp lands on the correct card while the other choices remain available to discuss as near misses or misconceptions.
