Ordering Numbers from Greatest to Least

Daily Review:

As a reminder, we will look again at the number line, remembering that numbers closer to zero are smaller than those further away.

Statement of Objectives:

To review the concept of greater and least.

Presentation of Information:

Students will use a variety of sources to learn this concept. We will utilize the overhead projector, index cards, and a string with markers placed on it to represent the number line, Inspiration software, and the classroom textbooks.

Guided Practice:

In small groups (2-3 students), we will look at the number line, and at a page in the text book. Students will be given a set of index cards with various numbers on it. In their groups, students are to place the index cards in order from smallest to largest, keeping in mind where the zero is on their number line. After the teacher checks each group’s work, students will be asked to remove the index cards, and place the zero marker at the other end of the number line. Students will then place the index cards in order from largest to smallest. Again, work will be

Independent Practice:

Next, students will complete the Inspiration worksheet, Greatest to Least, in which they will manipulate the numbers, arranging them in the correct order. The teacher will check individual work.

As an extension of independent practice, students will take the string used in the guided practice exercise, and after generating random numbers, they will arrange them on the string, keeping in mind where zero is.

Formative Evaluation:

To assess student understanding, the class will play a game, in which each student randomly draw seven numbers out of a hat, and must place them in order. This will be done on multiple occasions, in order to practice the concept. Additionally, more formal assessment will come at the end of chapter test.
