For those with a classroom economy system or Class DoJo, this year my students have been balancing a checkbook to keep track of their "money"!
Super easy! I took a bunch of notecards, stapled them together, and ta-da!
We had 3 columns; date, deposit/withdrawal (for differentiation +/-), and balance.
We balanced every Friday and students worked to earn money weekly. They really bought into this but I made sure to have things for them to "buy" each Friday- pencils, pens, homework pass, extra computer time, lunch with the teacher... etc.
Also an AWESOME math activity you can adjust for each grade (just add decimals or round out the numbers!)
