Model mixed numbers with units of hundreds, tens, ones, tenths, and hundredths in expanded form and on the place value chart

In this lesson, students model decimal numbers to hundredths on the place value chart, and then represent those numbers in fraction and decimal expanded form. They also discuss the symmetry of the place value chart, determining that the ones place (rather than the decimal point) is the "mirror" for tens and tenths and hundreds and hundredths.
