After beating my head against a wall and causing my ever-patient homeschooling friends to want to beat their heads against a wall due to my incessant whining about our math struggles, I finally took the advice of all three of those friends and ditched our math curriculum (for the time being). Instead, we do kitchen math, mental math, math games, games that are not math games but that require math skills (like Yahtzee), and work from the incredible "Math Pamphlet" that my good friend made for AC. (That's a whole other post. It's really wonderful.)
In my search for ways to work on math without it seeming like we are working on math, I came across the Exact Change Card Game. Not only is it a great way to teach money skills, but it is perfect to teach children how to add a series of numbers with regrouping. I have AC do all the adding for all of us. It's great practice and is a good confidence builder for her. I think it's really going to help. Hopefully, we can start our Singapore Math curriculum again soon.
