In this lesson, students count on the place-value chart by ones from 0 to 124, bundling a group of 10 tens to make a hundred. Then they count from 476 to 600 using various units (4 ones to get to 480, 2 tens to get to 500, and 1 hundred to get to 600). Along the way, they represent numbers in standard form (i.e. with numerals). For example, they represent 5 hundreds, 6 tens, and 3 ones as 563.
