I'm hoping the humor comes through as funny as it actually was (or at least as funny as I thought it was).
I'm teaching fifth grade - so they're typical 10 year olds and I have some great 'personalities' in my class and this was part of my math lesson today...
The kids were doing a word problem that involved several different sized "bouncy balls" - Now why a textbook company would write a word problem for 10 year olds about bouncy balls is beyond me. But needless to say, several of my boys started giggling.
Then it got a little much and one kid loudly says, "He's talking about the OTHER BALLS!"
So I say, "What balls are you talking about?" (how I kept a straight face is beyond me)
The kid was speechless (and I was trying so hard not to laugh).
I asked again, "What balls?"
And another (smart) kid chimes in, "No no no Ms. K, he was talking about the 75 millimeter balls - the problem was talking about the 40 millimeter ones."
Ahh I see...so he was talking about the bigger balls.
You just can't make this up.
