Three Digits with Numerals (1)
In the next lesson I encouraged her to
work only with numerals alone - no icons.
What To Look For In This Video
- I am impressed by how easy it is for her to move from icons to numerals.
- I am impressed that she is able to solve the problem "in her head." That is, she doesn't record any intermediate steps.
- I am also impressed by her articulation of the logic. "I basically did the same thing I usually do with the ones - but with the tens and hundreds."
