Now that dd5 has been out for summer from official school, part-time though it was, for a whole month, here's a list of what we do to keep educating her:
1) Nearly every weekday morning, we do 30-45 minutes of formal schooling. It includes 5 minutes of writing practice (copy one short sentence), 20-30 minutes of math (usually 2 pages from her math workbook), and 5-15 minutes of reading instruction from Reading with Phonics.
2) Much watching of Sid the Science Kid has been happening. I like the song that goes "I love my mom, my mom is cool."
3) We have occasional music lessons and went to a children's concert.
4) She is done with the library's summer reading program, and it did indeed jumpstart her reading on her own.
5) She doesn't let a day go by without doing something crafty: coloring, painting, paper plate masks, etc. Often her crafts are inspired by a book we've just read, such as the swans she painted today after we read The Ugly Duckling.
We also just play games, garden, visit friends and family, and go to parks. Summer is hot, and life is good.
