While education in the short-term after a disaster should not be a problem, imagine if you were unable to send your children to school for months or even years. This is a something that many families will face should education facilities close. The most fundamental skills we take for granted will be lost. Now I am not speaking of medical skills or law degrees but basic literacy and math. It will be imperative to acquire text books and materials that you can use to teach the next generations.
One of the simplest ways of acquiring text books is through online education sources. You can simply go online and purchase the ones you need. Another source of inexpensive text books is your local Good Will store they supply many useful gently used texts from students and universities.
I would suggest making a list of subjects such as math,science, and English and obtain a small collection of materials that you can use should the need arise.
