Understanding "Place Value" in math is crazy-important in our math program. They must know the value of each digit in a number. They need to know what it looks like when you add 10 to 2,456, or subtract 100 from 3,789.
We don't want them just writing on paper...we want them to SHOW us what that looks like concretely.
I was quite impressed at how they worked so well in randomly chosen partners. Everyone stayed on task.
Nicely done, boys and girls. I'm very proud of you!!
