How about teaching while she's active? For example, let her do jumping jacks or jump on an indoor trampoline while you read a short story, then ask questions about the story. Or if she's practising their addition or multiplication facts, she could do it to the rhythm of the jumping: "3-hop-times-hop-2-hop-equals-hop-6-hop."
Or, tickle time? Kids get so spent when they're tickled! Plus it's a great parent-child connection and doesn't take long to be effective.
Maybe she could do worksheets in teh car coming home from a physical activity like being at the playground or a gymnastics, swimming, etc class?
