So if you drag an extra letter into the white space and then realize it, you can’t fix it. The “undo” and “clear” options only apply to the handwriting portion (awesome, by the way). Perhaps it is a bug, just on my newer iPad? ### 5/5 — Perfect for older students *2019-11-03* This is perfect for students who want to improve their reading and spelling of multisyllabic words! ### 5/5 — WordBuillder Intervention is great! *2019-11-01* I have just started using WordBuilder with my struggling readers and they love it. I enjoy working with students in the WordBuilder application, directing them to break down words and then build them back up again. The reward games are simple but fun and I appreciate that students have to earn enough coins to be able to play. ## Frequently asked questions about WordBuilder Intervention ### What is WordBuilder Intervention?
