Use Color Pages
Toddlers love to do art projects and color, so you can't go wrong when you bring in color sheets that feature pictures of ducks on them. They can be found in coloring books or on the Internet wherever there is preschool farm art color pages or at other websites that are dedicated to providing free coloring sheets for classrooms or homes.
To find coloring pages with pictures of ducks on them, simply go to a favorite search engine and type in "duck coloring pages" and there should be a plethora of websites that show up. Browse through a few till a favorite is found. Print out one and make photocopies for all the toddlers to color. Keep a few extra copies in case there are any accidents or a page gets torn.
You can also open a Word document, click on Insert, choose Clip Art, and on the right-hand window that opens up type in Duck. You will have many choices of ducks, and once you've chosen one that's mostly line-drawn, insert it into your page. Right-click on it, choose Format Picture, select Picture Color in the window that pops open, and then at the Recolor button when you drop it down you will be able to choose a line-drawn black-and-white version of your duck for all to color.
Give one color sheet to each toddler with some crayons and have them color away! Encourage the toddler to be creative and use their favorite colors on the page.
Once they are finished coloring, assist them in putting their name and the date to the color page for those who want to display it or put it away as a keepsake.
