This free online tool lets you generate 20 random questions that test any of the following conversion: - binary to decimal - decimal to binary - binary to hex - hex to binary - decimal to hex - hex to decimal

You can choose any combination of the above and get students to work through 20 questions then take in their scores.

Scores are given for correct answers but you also get a measure of accuracy and speed too.

Hope it’s useful.

I also use this visual aid for teaching binary:
