I'd pick a topic, and go with that til she's ready for another topic.
Example: snow and ice. Cut out snow flakes, make a snowman (picture or sock, read any wintery books you have in the house (or choose them from the library if you can get there), make frozen ice lollies (and eat them!), see how to speed up icecubes melting - in small pots, leave one on the radiator, one in the room, and one in the fridge. Get her to predict (and write /draw) what she thinks will happen, and then keep an eye on them. Watch Frozen to give Mummy a break.
Minibeasts, dinosaurs and sea creatures are other topics we've had from school recently.
If you know what school she is going back to, could you ask what broad topics they are covering. You could then do that topic so she has covered some of the same material as her peers, all be it in a different way?
Would she "write" a diary for her time at home? Could be a picture, dictated words to you, something she has made (photo it if needed), or a few words of her own each day to remember these weeks?
