Have your students practice place value with decorating pumpkins. Each pumpkin requires students to used Standard, Word, Base 10, and Expanded Form, as well as 10 more, 10 less, 100 more and 100 less. Great way to differentiate by assigning your own numbers for each student. Students can create 2 and make them 3-D to hang on a wall, or make 3-4 different ones to make a full circle and hang to display.
