Over the summer we will be testing out BA and TT for math to decide which one she prefers to use for 4th grade (I'd put money on BA).
She has a book list for 4th grade that she'll begin to work on over the summer and we have a solar science unit planned.
For fun planned things DD9 has soccer, cheerleading (year round), learning to hike 14ers, and general relaxing and being bored with other kids.
For 4th grade starting in August:
Math: either BA or TT with lots of games for reinforcement
Spelling: Sequential Spelling - finish book 1 and move on to book 2
LA: lots of books, interactive notebooks and task cards that I purchased from TPT
Science/health: Homemade units on Chemistry, evolution, genetics, cardiovascular system, digestive system, and immune system
History/art: Lots of books from the library and interest led projects on modern American history
Social Studies/Civics: Basic world geography, US geography, a unit on presidential elections, learning about the history of Washington DC (DD9's request), and a Colorado unit study with planning a trip around CO for the summer
Communication: Giving oral and visual presentations at the end of her units to mom and dad or on video
Technology: Minecraft mod and server coding, photo and video editing (by request) and possibly building her own desktop computer with DH
Spanish and Music are at her options program on Fridays along with extra science projects, LA practice and PE
She'll also be continuing with Girl Scouts next year
