Lesson 10-6: Remembering Formulas (Day 106)

Today I subbed in a middle school special ed history class. It is in my first OC district. And I've visited this classroom before -- I described my most recent visit almost a year ago, in my February 28th post.

And it appears I'm again in the middle of a stretch where almost every job is special ed -- as we've seen before, this district is prone to scheduling special ed meetings at the same time. This means that once again, there's no "A Day in the Life," since there's one class is co-teaching and the other two have an aide.

The fourth period co-teaching class is seventh grade World History. and that class is currently studying feudal Japan. But while the fifth period special ed is also World History, they're studying West Africa instead of Japan. One of the documents they use today is labeled "Black History," so this unit might be a way to link World History to Black History Month. And the students are using this document to prepare to write their own -- you guessed it! -- CER (Claim/Evidence/Reasoning) essay. So February isn't just Black History Month -- it's CER month, at least in this district.

The sixth period class is an eighth grade U.S. History class. The students are taking a quiz on the Constitution and the Federalists. In both classes, I tie the lesson to the current imp----ment trial that's going on in Washington DC -- for seventh grade I mention that both sides are making claims and showing evidence to support those claims during the trial, and for eighth grade I point out that the First Amendment on freedom of speech is being appealed to by the defense.

Today is Fiveday on the Eleven Calendar:

Resolution #5: We treat people who are great at math as heroes.

Obviously this is a bit tricky in a history class. Indeed, I don't mention heroes or pay homage to anyone at all today, unless you count Mansa Musa as a hero. OK, I'll count Washington, since he presided over the Constitutional Convention and his holiday is coming up in a few days.

But I do sing songs in fifth and sixth periods today. The songs that I've associated with this time of year, from my days at the old charter school, are the "Row Row Row Your Boat" parodies -- namely "Measures of Center Song" and "Same Sign Add and Keep."

Lesson 10-6 of the U of Chicago text is called "Remembering Formulas." In the modern Third Edition of the text, remembering formulas appears in Lesson 10-5.

This is what I wrote last year about today's lesson:

This isn't exactly a filler chapter, since students indeed must remember surface area and volume formulas. It's just that students can learn all of these formulas without the benefit of Lesson 10-6. The important part is that some formulas are clearly linked -- such as the formulas for a prism and a cylinder. It's no wonder then that the text calls both of these "cylindric solids."

...and that's all I wrote last year! So this is a rare short post of mine.

Let's get to today's worksheet:
