In this lesson, students learn to identify place values to one thousand by name. The problems in this lesson are of two forms: 1) they are given a number and must write the digit in a specified place, and 2) they are given a number and must select the name of the place occupied by a specified digit.
In this lesson, students learn to recognize numbers written in words as a specified number of units, tens and hundreds, then write the number represented. The number of units, tens and hundreds, are written in random orders so that students must interpret the meaning of the values and not simply write digits in the order of the words.
A number line is introduced as a way to show properties of numbers. Each successive point on the number line is labeled by adding one unit to the prior point. Since the points on the number line are ordered in the same order that numbers are counted, numbers get larger going to the right.
That means that if a number is to the right of another number on the number line, it is larger than that number.
In the problems in this lesson, students must label a specified point on a number line that extends from zero through 10.
