Toddlers and preschoolers love life skills activities. These stimulate so many senses and skills. Large and fine motor skills, eye hand coordination, prediction, etc. They are also inexpensive and easy to set up. Here are two we recently did. My daughter loved spooning the lentils with the little spoon. The 3 year old I was babysitting wanted to do the pouring into a cup and then pouring back into the bottle with a funnel over and over again. It was messy at first but she soon caught on how to do it. I got all the things in this post at the dollar store.
