Dear Otto is an occasional column where I answer questions I get from readers about teaching tech. If you have a question, please complete the form below and I’ll answer it here. For your privacy, I use only first names.

I received this question from Mary.

I teach Media Production, where my year 9 students get creative with Adobe Photoshop, Audition, Premier Pro and Stop Motion Pro. They have a wonderful time, but I would love to be able to provide them with a way of keeping a digital portfolio of their work. Our school runs Blackboard, but the digital portfolio add-in is very expensive, too much for our small school.

Are there any free web-based options I should know about, or less expensive ones?

Thanks!

Hi Mary

Have you considered getting students signed up for wikispaces? You can create a free wiki, add each student as a member and let them create their own page, then they can embed each project right onto their wiki page. I did this with 5th graders last year and got some beautiful results (albeit mixed because of the age. Some got it; some glazed over).

Every Friday, I’ll send you a wonderful website (or more) that my classes and my parents love. I think you’ll find they’ll be a favorite of your students as they are of mine.

Summer is when parents worry about math facts and the automaticity of math skills. The following websites focus solely on that facet of math.

I’ve broken them down by grade level, but you can decide if your second graders are precocious enough to try the websites for grades 3-5:

There are an awful lot of math sites on the internet and too often, they are filled with distracting ads that make it difficult to find the learning material, or too many games that don’t so much teach math skills as babysit kids.

Here are some I’ve found useful in my technology lab. They’re straightforward, with an uncluttered interface (mostly) and a focus on teaching not entertaining:

Math and Virtual Manipulatives and Tessellations –well organized, using a whiteboard with shapes and colors as the virtual manipulatives.

Math website—popular, a standard

Math—by Grade Level–a longtime favorite that reinforces basics, math facts and speed math

Math–Mental Math –traditional mental math practice. Well done.

Math–Minute Math –Mad Minutes

Games that make you think –logic, for K-3

Multiplication.com–lots of multiplication problems, lessons, games, with a few on addition and subtraction

Interactive Math Lessons–lots of them. You’ll find everything you need here.

Can the level of math education sink any lower?

Teaching Math In 1950:
A logger sold a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit?

Teaching Math In 1960:
A logger sold a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?

Teaching Math In 1970:
A logger sold a truckload of lumber for $100. His cost of production is $80. Did he make a profit?

Teaching Math In 1980:
A logger sold a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment: Underline the number 20.

Teaching Math In 1990:
A logger cut down a beautiful forest, because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living? After answering the question, the topic for class participation is: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers.)

The Result In 2005:
Last week I purchased a burger at Burger King for $1.58. The young woman at the counter took my $2. I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies while looking at the screen on her register.

I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried.
