" ALI MADE A MODEL FOR 624 USING 6 HUNDREDS, 2 TENS, AND 4 ONES. WHAT IF ALI HAD NOT HAD ANY TENS? HOW COULD SHE HAVE MODELED 624 WITHOUT USING TENS?...

I have no idea what 624 is or means but I assume it is money or some kind of counting (but I don't know how one models money :)].
Ali could have used 5 hundreds, 6 twenties, and 4 ones (no tens).
If I have interpreted incorrectly, please repost and clarify. 
Well, I have been out of 3rd grade for awhile, but i am in middle school:)
I think Ali could use 6 hundreds, and 24 ones. Therefore turning the 2 tens into ones (2x10= 20) and adding the ones she already had (20+4=24)
~Hope I helped;)
