Wednesday: 10 more and 10 less
Oliver has 345 pinecones in his tree.
Bennie brings a bundle of ten more.
"How many now?" asks Oliver.
"We do not need to count them all," says Bennie.
"Ten more just adds one ten."
"Only the tens digit changes. Let me show you."

345 has 4 tens.
Add one more ten, and it has 5 tens.

Count the hops from 345. There are ten!
10 less than 345 is 335.
