[I’m going to devote my Thursday blog posts to the topic of All Things Academic: reading, writing, ‘rithmetic and the other school subjects.]

Last week I said that I see value in having kids (and all learners) memorize a certain amount of factual information.

I also said that I’m not a fan of rote memorization of multiplication “facts.” Kids should also be learning when and how to apply all of the four operations to various situations.

My favorite way to teach arithmetic is by using word problems that kids write themselves. Put them on separate file cards and have kids solve each other’s questions.

When kids write and solve one another’s word problems, they practice reading, writing and math, all at once. They also develop empathy as they consider what subject matter might please their classmates, how hard to make their problems, etc.

I have an extensive collection of Wonderful Word Problems. Here’s a sample:

• What if Rudy had 6 puppies and each one wanted 2 dog biscuits? How many biscuits would Rudy need for them?

[I’ve decided to decorate Thursday’s posts with images of man-made objects, which seem to convey the peculiar beauty of the logical human mind. There’s something multiplicative in these window panes.]
