This past Monday, for Family Home Evening, we decided to work on Andrew's Webelos Cub Scout badge and have a discussion about budgeting and family finances.
Me (after an explanation of what a mortgage is): Who knows how much we pay every month for our mortgage?
Andrew: Yeah, oh, I think it's $300 to $600
Sophie: 8 minutes
Me: How much do you think we spend on groceries every month?
Andrew: $30 to $100
Sophie: 6 minutes
We had a good (eye-popping and jaw-dropping, at least on the kids' part) discussion about finances.
