Homeschooling Doesn't have to be expensive if you are inventive! Gradelevel workbooks can be expensive. Why not reuse them? Your child can practice their skills by re-using the pages, and younger siblings can use them later. Tear pages out and put them into sheet protectors and use a dry erease or wet erase marker for writing! I use wet erase markers and wipe them off with either a baby wipe or a spray bottle with water and a paper towel.
