I use this with my students before we start our keyboarding program.
This purchase includes 1 blank keyboard, 1 colored keyboard, and photo examples
I put the colored example on the Smartboard and give students a copy of the blank one. Once they've colored their keyboard to match mine we talk about the color coding of each key with the correct finger and home row. Sometimes I even place colored stickers on the keyboards or students' fingers. When we begin using keyboard covers I allow students to use this sheet as a reference.
