We've used Thinkster for years for math and love it. It's a combination of one-on-one time with your assigned coach once a week, and online worksheets with thinkster produced videos that explain each concept that is the focus of the worksheet. You get a free 7-day trial, so make sure you sign up for it when your kid's schedule is flexible enough to take advantage of it.
Happy to answer any questions you may have. https://discover.hellothinkster.com/lp/get-free-trial?tm=tt&ap=gads&aaid=adaUSz8PsTmma&wickedsource=google&wickedid=CjwKCAiAxKy5BhBbEiwAYiW--6WstxUqMyo3PkRLbJWQcI_h9LZJnMmZpP8VH4SaT2OfaH-6os8exxoCBXEQAvD_BwE&wickedid=663407942592&wcid=14950163202&wv=4&gad_source=1&gclid=CjwKCAiAxKy5BhBbEiwAYiW--6WstxUqMyo3PkRLbJWQcI_h9LZJnMmZpP8VH4SaT2OfaH-6os8exxoCBXEQAvD_BwE |
