Post-office numbers
http://illuminations.nctm.org/LessonDetail.aspx?ID=L217
A lesson plan for grades 3–5 Mathematics
In this lesson, one of a five-part unit from Illuminations titled “Numbers and Language,” students participate in activities in which they focus on the role of numbers and language in real-world situations. Students discuss a picture of things you might see at a post office, and then discuss, describe, read, and write about whole numbers to thousands, decimal fractions to hundredths, and common fractions.
