Welcome to our little corner of the internet! Touchscreens make using your personal devices much easier, so I'm sorry to hear the one on your Insignia tablet has cracked. These parts aren't available as one-off items that can be ordered, so I would recommend bringing your tablet to your local Best Buy store for service through Geek Squad. You can schedule an appointment online here, or call (800) 433-5778 to do this over the phone.
I hope this helps! Thanks for reaching out.
