### What is the value of 4 in 47? How do you know?

4 tens or 40; 4 is in the tens place, so its value is 4 tens or 40.

### What number do you get when you add 1 to 29? Explain.

29 is 2 tens and 9 ones. 1 more one makes 2 tens and 10 ones. 10 ones is the same as 1 more ten. That gives me 3 tens. 30 is 3 tens. So the answer is 30.
