Dry Erase Boards are great for writing out thoughts and ideas. They Are useful in mapping out things. They can be used to chart things and clarify situations. I LOVE them! I use them in my life for some of my larger ideas and concepts and/or when I am fleshing out a new idea. And you can erase and change anything on the board at any time!
Now they come in tons of different sizes. I like the big ones the most! I like to SEE it! But I do have a few medium size ones. My cousin has the small 5 x 7 decorative ones. There are also those out there that go by days of the week (and month-long ones too). Just some thing to think about when you are planning. Or want to write out a chore chart for the kidlets. Dry Erase boards are totally versatile!
