Do you use printable resources? Check out Teachers Pay Teachers for free and cheap resources!
Teachers Pay Teachers is an online marketplace where teachers (and homeschoolers) buy and sell original educational materials.
Just search for what sort of resources you need, eg: "Australian Money" then narrow down the results using the approx age level on the left, as well as your maximum price and the resource type. Try to be as specific as you can - I just searched for Australian Money resources for P/K/1 level and there are over 850 items! Please note that prices are in US dollars.
For US$5 I just bought a 56 page pdf download with 4 games I can print and use right away. It has lists of what we need (eg: dice, counters), cards, game boards, instructions, and "coins" (but we'll use our plastic ones or real money).
I played (and made) a few money games with my older children when they were young. I found it gave them the confidence to go into a real store and hand over the correct money, and/or remember to wait for change.
We've never tried teaching about money using worksheets, we just use play and real life. I'll share another resource about money next week...
