We used Typing Instructor for Kids.

DD liked it at first, but then not so much.

What really improved her keyboarding skills was the need to communicate that way in real time in a virtual meeting setting. She wanted to participate with her classmates, and the only way to do so effectively was to learn to type.

She probably types about 50-60 words per minute now.
