Masking tape and a ball point pen. Stick masking tape down on the ground all around the house and draw dotted lines along the middle. Voila, instant road for them to drive their cars along.

go and discover the out doors or the backyard! take them somewhere to ride their bikes.

Get them out in the garden. Take them to the park or the local swimming pool/beach. Get them in the kitchen cooking. Games are always a great time filler

My boys (2 and 4yrs) love balloons, trips to the park, bubbles, home made play dough, paint with water books, drawing/colouring, stickers, duplo/blocks, crafting, tea parties, making a forte, baking, playing cars all over the house and running around outside. I hope these help
