Borrowing on an idea found here on a very awesome preschool blog we headed outside last week to make art.
Each older child was partnered with a little one (while I have to keep track of everyone, of course, partnering helps everyone stay safe, especially outside) and all were given simple instruction. Take what you find in the yard and make something that you'd call art. Before we began two of the little ones headed home so some of the partnerships were broken but everyone adapted and excitedly moved forward.
Their end results are shown in the images. Three very different ideas.
