I am not suggesting that these sorts of activities can entirely replace book learning. These life lessons can supplement and reinforce what your children are getting from class, adding more tangible value to the content they are getting from their books.
Some people think of audiobooks as a form of entertainment or means of self-improvement. We should consider them as an educational resource in our homeschooling as well! A good audiobook is fully able to stand as an integral part of your Catholic homeschool.
