I learned about a word window at a homeschool meeting a few years ago. When children are learning to read, sometimes they become overwhelmed when they see all of the words or just big words. A way to get around this is to use a word window. That is what I call it anyway. I'm not sure what official name it may have. What it is is a bookmark that you cut a rectangular square out of the middle that would be the length and height that would fit around a regular sized word. Zoe uses this sometimes. Ours is made from a foam sheet so it feels smooth, comfortable, and maybe even a bit more fun than just using a regular piece of paper. With a word window she can focus on each word without being overwhelmed by all of the other words around it. It helps the child to focus on each word until they get more comfortable doing it on their own.
