To use these sheets, I put them inside a sheet protector, that way students can continually use them and then wipe away their work. I put them front to back and slide them in, so we can use both sheets for my one lesson. Side 1 allows teacher and students to practice learning the place and the value for each digit within a number. Side 2 allows teacher and students to practice writing a number in Standard Form, Expanded Form and Word Form. They have really helped me teach and my students learn place value. I hope they work for you!
