I found this collective nouns app today after a fit of desperation! There is not a lot out there as far as fun and games for this skill that is adequate for second and third graders. So, today I did a search on iTunes and found this app for $2.99. I grabbed it. Even if it isn't that great, it still allows me to teach this skill! If you would like to go check it out, just go and click on the button up above! Hope this helps!
