This website has a lot of great, fun and creative ideas to help students practice place value. My favorite is the ice cream cones. Students get to build ice cream cones but matching the numbers and different ways to write the numbers.

Place value activities to do with "The True Story of the 3 Little Pigs". I would have never thought to use this book to teach place value. Great for lower elementary. I adore this version of the 3 little pigs!
Place Value Paint Samples. could make this larger to add places. Going to have to get the paint chips with more colors to make bigger numbers. Would be great help for my students who still struggle with place value.
