Unlucky Charms

In Math we learned all about number sentences today.

Here are some examples of number sentences:

• 3 + 9 = 12
• 4 * 19 > 20
• 45/9 < 23

These are not number sentences:

• 59 - 36
• 6 * 73
• 8b

As I told them, the equals, less than, greater than, and signs like that act as a linking verb to the predicate nominative. It's actually pretty interesting to think of it that way.

The trickiest part of this is remembering that you have to start using PEMDAS on every problem from not and for the rest of their lives, so...

• 5 + 3 * 6 = 23 is true, and 5 + 3 * 6 = 48 is not true. 

I handed out a vocabulary list for a quiz on Friday. There are only eight words!
