## Learning Objectives

Students will be able to compare two numbers between 0 and 10 using greater than, less than, or equal to.

## Lesson

### Introduction (5 minutes)

• At your group meeting area, choose two students for a demonstration.
• Give each student a paper plate and some marshmallows, or other manipulative, making sure they do not get the same amount.
• Ask students who has more or less marshmallows and how they know.

### Explicit Instruction/Teacher Modeling (10 minutes)

• Tell students that they have just compared numbers, which is what today's lesson is all about.
• Watch Urple and Burple.
• Stop occasionally to talk about how many of each object Urple and Burple have and who has more of each.

### Guided Practice/Interactive Modeling (10 minutes)

• After the story, introduce the vocabulary: greater than, less than, and equal to using the reference posters.
• Using the marshmallows, or other manipulatives, show examples of greater than, less than, and equal to.
• Once you have modeled a few examples, invite students to make the symbols with their hands to compare the two groups. Repeat as needed.
• Show students how to make the cereal holders using marshmallows by sticking 1 toothpick in each marshmallow and then placing cereal onto the toothpick.
• Remind students that they are using the marshmallows and cereal as tools to compare two numbers.
• Model using the cereal to show a number on each of the toothpicks and recording it on the recording sheet.
• Then ask students what symbol should go in between the two models. Model writing the symbol in between the two marshmallows on the worksheet.

### Independent Working Time (15 minutes)

• Back at studentsâ€™ seats, pass out the Comparing Numbers with Marshmallows worksheet and prepared paper plate to each student.
• Circulate the room to guide students and check for understanding.

## Extend

### Differentiation

• Enrichment: Give advanced students verbal queues for them to determine greater numbers. The Comparing Numbers Quiz is a good way to do this.
• Support: Give struggling students the Comparing Numbers worksheet for their assessment.

## Review

### Assessment (10 minutes)

• Distribute the Fruity Number Fun worksheet and read the directions aloud.
• Check these worksheets for correctness.
