Shaving cream painting. Get them to practise writing letters and shapes in shaving cream spread on a table. Buy the cheapest can at the supermarket.
Doll washing – set up a towel, small soap, face washer, doll clothes, towel etc. Let her make a bubble bath in a container. Can also wash the dolls clothes, rinse them, wring them out and hang up with pegs to dry.
Make fairy houses outside with bark, moss, leaves, flowers, stones etc.
Paint the fence or a wall with water.
Make drawings out of fingerprints. Use an inkpad to make a fingerprint then using a fineliner turn it into an animal.
Sort buttons or beads. Get out your collection of buttons and beads. Tip them out onto a tray then let her sort and play with them (supervised as there is a choking risk)
Make homemade playdoh.
Have fun

What “activity” area are you after?

Coloring and drawing can be great. I’m always an advocate of books. And simple board or card games if you really feel she’s advanced.

I dont think 2.5 yo’s really need ‘tasks’ per say but more getting out side in the fresh air and exploring or playing at playgrounds etc. Let kids be kids and play. If you need to be inside playdough or painting and sensory play is always fun!

Dancing helps if theyre busy

You can’t go wrong with Lego, jigsaws, books, art & craft activities, outside play, pre school activities, science activities and maybe some Reading Eggs

Lego, my son has learned so many skills building things from the booklets. Instructions are downloadable too.
Another activity I do is instruct them to fetch letters off the fridge, we practice writing them or find something that starts with the letter.

Get a balloon and write letters on it and use it with music, point to random letters or identify the ones we touch as we catch the balloon.

We made clocks with my eldest, when she was about 3, using cardboard and butterfly clips so the hands could move. We then placed them on the wall with a real clock and had the activities for her to do at certain times. For example; eat breakfast, do your teeth, have a bath etc. We would set the clocks and put the chore or activity under that time. When the proper clock gets to the time on the made clock the child does the activity or chore. My then little loved it. She felt independent and learnt to tell the time.

Outside messy play. Get creative and crafty, threading dried coloured pasta or learning how to braid. Make dream catchers with beads and cotton. Or diamond dot painting.
Make scones or bread together.
There are some great science kits at Kmart, or the gear bot Lego sets.

Also a good idea with children that absorb information and activities to look at Science based activities; they can be challenging and also fun. We invested in science and activity packs.

Could you just let her have a “free play”and let her imagination run wild… set out a few toys, activities and let her take charge

Rather than giving her tasks with a goal at the end I’d let her be creative and do things on her own. Kids learn with sand, playdough, painting, stacking, cooking, balls & bats and general play with toys – using their imagination.

We set up different stations in the family room; messy play, creative play, building play, craft play, etc. We purchased books on activities and these books can also be borrowed from a library. A local library might be an excellent resource for searching for books and getting ideas for toddler play based learning.

Get her at the bench with you and teach her some kitchen skills. I recently let my 2.5 year old hop up on her stool at the bench and chop (butter knife) up some soft banana for her baby Brother. She absolutely loves the practice and feeling so accomplished with her job. I’d recommend common household practices that she can handle at her advanced mental age and would enjoy.

There are some really great Instagram accounts you can follow, they have really fabulous craft type activities for toddlers that you can do at home with things around the house. Also try places like Red Dot, Reject Shop, they have lots of craft type activities that are cheap. I always have a few packed away for rainy days that i can pull out.

Sensory play: Explore different textures (shaving cream, water beads, homemade playdough), make “potions” with colored water and kitchen tools.
Open-ended art: Provide a mix of materials (paint, markers, yarn, glue, feathers) and let her create freely, without a specific outcome in mind.
