Most homeschoolers feel at least a small tinge of panic as their students approach high school. “What have we gotten ourselves into?” we wonder. “Can we really do this?” Here are a few tips to make the transition easier.

Before you move forward, it may help to take a look back. How has homeschooling worked for you and your children so far?

If your students hate math, they probably never got a good taste of the “Aha!” factor, that Eureka! thrill of solving a challenging puzzle. The early teen years may be your last chance to convince them that math can be fun, so consider putting aside your textbooks for a few months to:

On the other hand, if you have delayed formal arithmetic, using your children’s elementary years to explore a wide variety of mathematical adventures, now is a good time to take stock of what these experiences have taught your students.

  • How much of what society considers “the basics” have your children picked up along the way?
  • Are there any gaps in their understanding of arithmetic, any concepts you want to add to their mental tool box?

Good News for a Change

As I was checking through archive posts and clearing out the dead links, I found a couple of links that I thought would be dead but which are still good. So I am re-posting them here, for your browsing pleasure:

Free Shakespeare for Fun and Copywork

CurrClick (which carries the Math Mammoth workbook series) is offering Quotations from Shakespeare’s Plays as a free download. This ebook includes copywork tips from Charlotte Mason and about 30 pages of passages from Macbeth, King Lear, Much Ado About Nothing, etc.

[And if you are planning a study of the Bard, you won’t want to miss the many other Internet resources in my original post.]

Great Leaders in a Crisis: Lincoln, Churchill

What does it take to lead your nation through a crisis? Character, determination, wisdom, the courage of your convictions. What can we learn about leadership from those who have been there, done that?

Abraham Lincoln and Winston Churchill are two of these great leaders — men whose courage and conviction took their nations through challenging moments and forever altered the course of Western civilization…

The Teaching Company (one of my favorite resources for homeschooling high school) is offering two free lectures for the downloading: Great Leaders: Abraham Lincoln and Winston Churchill.

Salman Khan: Reinventing Education

This reminds me how many years it’s been since I updated my Math Resources page. Khan Academy is just one of many links I’ve been meaning to add. Someday, I’ll get caught up on the urgent stuff and have time for all my good intentions. . .

[Update: For those of you whose rss readers don’t show TED videos (or is mine the only one?), you can see this at Let’s use video to reinvent education.]
