Just couldn't resist this one...How good it will feel to vent!
The older I get (and I'm getting old much too fast, let me just tell you!)the more I am amazed by the failure of our modern educational system to provide a solid grammatical foundation.
The truth is, no one with a busy life gives a hoot about antecedents and whether a noun is singular or plural -- and that's why it's so easy for improper usage to sneak in and become the accepted usage.
The easiest way to avoid this dilemma at all times is to insert the word "members" any time you try to use the pronoun "their" in a sentence referring to a class or group. It settles all doubt instantly and is a great little shortcut. Sometimes young children are better able to grasp a simple rule such as this one than to try to understand more complicated grammatical rules. Over time, this "rule" will plant the seeds to understand the concept of singular vs. plural.
The class is going on its field trip next Tuesday.
Class members will take along their field journals.
This group is cheering for its favorite team.

Some teacher long ago (and wish I could remember which one!) taught me this child-friendly "rule" and it has yet to fail.
Thank goodness for moms like you, A. B, out there fighting a war against the tide of bad grammar by stopping to check the rules before teaching a child the wrong thing! It's a lost cause, but I praise you anyway. Many moms would not have taken the time to check other sources when the textbook stated something that seemed untrue. You are lighting a single candle against the encroaching darkness, and I couldn't let the morning pass without recognizing and thanking you!
While I'm on my annoying, rant-and-rave soapbox, please let me take a moment to point out my other pet peeve grammatical boo-boos that are masquerading as proper:
Alot -- is not a word. Always put a space in between the word "a" and the word "lot."
Flyer -- is not a piece of paper distributed to the public to market services, products or events. The proper word for that is "flier" with an "i" instead of a "y"
Its -- does not require an apostrophe UNLESS you are using it to mean "it is.
These are the rules I am drilling into my own children, to do my own small part to change the world.
I wish I could also change all the mailboxes in my neighborhood and all the Christmas cards that we receive each year with goofy usages of family names. That one really boggles the minds of many people, who all seem to want to avoid adding "es" to the family name and wind up incorrectly adding an apostrophe instead.
You know, if half the neighborhood thought 2 plus 2 equaled 5, I am certain someone would set about correcting this problem. But no one much cares about grammar. In today's court, Math is king and Science is queen, and Language Arts plays the role of jester.
Sadly, the only people who will ever read this likely are the people like you, who already know better. The rest of the world simply doesn't care! :)
Thank you for your patience during my rant....
