You can create actual interactive activities that students can use. This is one I built in Gemini using this prompt:
Develop an interactive credit card simulation. Create a calendar that flips to the next month each time you click on it, starting with September 2025. Next to the calendar put a computer screen that displays a random selection of purchases that range from $20 to $100. As students click on any item, add it to a monthly credit card bill that displays underneath the bill. Underneath the bill place a bank account balance. In the bank account start with $1000. On the bill place a large blue button that says "Pay your bill". When they click on the button, ask them how much they want to pay. Give them 3 options: 1) the minimum payment which should be 10% of their balance, 2) pay off the bill in full, 3) pay another amount. If they select 3) then ask them how much they want to pay. Whatever they pay, deduct from the displayed bank account number
