Encourage the use of a variety of tools, colors, sizes, and fills. Older students might enjoy doing something like this as a more professional-looking presentation for younger students in the school. They could even write an accompanying story or set of questions too along with each slide. Assign children a number and have them create a page depicting that number and a picture illustrating that amount. Then print the pictures and create a book - or create a slide show.
Patterns are fun to create and are important for students to detect.
Allow the students to use any of the tools, shapes, or stamps to create pattern strings. After they've created a few, print the pictures - or if possible, have them switch seats with someone and see if they can add the next picture on each of the strings. Size relationships are easy to create in KidPix. Print and exchange with a friend. Have students illustrate the layers of the earth's atmosphere.
