KS1 activity at a TA interview Help

[OneUniqueCyanMember]

I have my first TA interview later this week, but the task they've given me is so generic that I don't know what to do. I have to do a 20-minute activity of my choice for a group of Year 1 children based on the KS1 curriculum. This just seems so generic and I'm not sure what I could achieve in just 20 minutes. Theyve also asked for me to read a book to another group later so i assume that means i cant read a book for the first activity.
Does anyone have any advice or ideas?

I’d choose a maths activity for the first one. Something practical or multisensory. Look on TES resources or Twinkl for ideas.
Choose a book with a character toy or story sack type approach. Repetitive text would be good to encourage joining in.
Think about questioning for both activities.
Don’t overthink it. Go for fun, impact, encouraging participation.
Don’t forget behaviour management. Set out expectations good looking, good listening etc.
Good luck!
