At supper last night, we had this little exchange among Middle Daughter (age 8), Youngest Daughter (age 5), and Ordinary Mommy…
MD (turning to YD): What’s six plus three?
YD (after a pause): Nine!
OM (quizzically): How did you know that?
YD (matter-of-factly): Because when you make a nine-patch and you have a group of six, you need one more strip of three.
Ordinary Spouse/Mommy/Homeschool Teacher laughs, because there are all these techniques for teaching addition, and then the child goes out and learns it from her quilting.
