A Moment of Teaching

I walk over and write a number on the sliding glass door. By the time I'm done writing, the children have gathered from their various activities, drawn by curiosity. Miss A shouts out the number "83!" 

I erase it and write another number and point to the first digit "ONE HUNDRED" and underline the last two. Miss H shouts out "57!" 

"Yes, ONE HUNDRED...fifty-seven." 

They get the next several 3-digit numbers, up to 999, that I simply write up then erase once they say them. 

I walk off. They disperse. 

In less than two minutes, I have provided a second introduction to 3-digit numbers. 

Teaching and learning doesn't have to be time consuming or complicated.

The children all turned 3, 3, 4 and 5 within the last two months.
