You can use this Cootie Catcher to have your kids quiz each other on writing numbers through millions. This file contains two versions to provide sixteen (8 on each catcher) numbers for students to write. Each Cootie Catcher has four 6 digit numbers and four 7 digit numbers. The answers are on the Cootie Catchers so that students have immediate feedback. One student reads the 6 or 7 digit number selected, and the other writes it down. Just have students cut, color, and fold, and you have a fun review activity!
