Going Mental

What a scorcher! Let’s hope we do not get too many days like this. The heat was oppressive for the students and the teacher alike. It was not a bad day, but by the end of the day the students were very restless and the teacher was too.

But going mental does not refer to anybody’s mental state. Rather, it refers to our math for today. It may be a hard assignment tonight. As we worked on it, it proved to be more complicated than I thought. Next year, I may approach this lesson a little differently.

The idea is to see if the students can do some adding and subtracting in their heads without paper and pencil. There are a number of techniques the book shows, but a couple of these frankly even confused me, at least when I tried to apply them.

So, do whatever works and try to do as much of it as possible without pencil and paper.

Homework:  (1) Do spelling sentences for words 11-20. (2) Do the Toto crossword puzzle. Be sure to use the word bank and to use the number of letters to help find the answer. (3) Do the “Tropical Rain Forest” study sheet. (4) Do Mental Math, Envision Math, pages 29-31.

We don't think the clue for number seven in the Toto vocab fits the last remaining word: it would mean that envious means excessively careful; cautious. The clue should be: jealous.

You're probably right, though I have the file on the hard drive at school. I make these up in a program called Vocabulary Worksheet Factory and then import them in. It's not a flawless program, and occasionally it does weird things like switching definitions or pulling them from other files.

My apologies here if I did not spot the mistake before scanning it.
