Reflection: Developing a Conceptual Understanding Crocodiles Love to Eat the Most - Section 2: Whole Class Interaction


The story in this lesson provides a foundation for students to develop the number comparison concept.  The story serves as a mnemonic for students.  "Fred" will help them retain how to use symbols (>, <).  I added some extra visuals by creating a real Fred.  You can use green and white paper, Popsicle sticks, and magnets.  I have included pictures of both a front and back view.  You can use the magnets to hang him on your chalkboard or better yet staple him to your calendar math center for students to refer to.  The story really encourages the students to focus and listen and interact with during the lesson.  I enjoyed their enthusiasm to assist me with the posters.

This lesson occurs really early on in my district when I am still teaching my students to stay quiet, raise their hand, and wait to be called on.  This lesson provides them practice towards this procedure.

Crocodiles Love to Eat the Most

Unit 1: Ordering Numbers
Lesson 1 of 7

Objective: SWBAT compare numbers using the symbols for greater than, less than, and equal to.

Big Idea: Students get very confused when asked to use >,<, and = to compare numbers. This lesson will show students how to make the crocodile eat the biggest number and free their mind to compare numbers and not focus on which symbol is the correct one to use.
