I use these trading cards while we are preparing for our Invention Convention and studying various inventors and inventions. It is a great way to have students research! I copy them back to back and then cut them in half. I have used both ribbons and book rings to hold the cards together after punching holes down the side or top! Students create their own cover using white cardstock paper cut in half.
You can decide how many cards students must complete! These also look great placed on an interactive timeline in the hallway or classroom! You can shrink them down if this size is too large!
