## Learning Objectives

Students will be able to understand and practice the concept of subtraction. They can also learn about the bugs as an added bonus.

## Lesson

### Introduction (10 minutes)

• Wear a funny hat with numbers and a subtraction sign glued on it (optional), and tell your students that they will be learning about subtraction.
• Read a book about counting backwards like Turtle Splash to introduce the topic.
• Draw students' attention to how the numbers reduce as each turtle in the story jumps off the log.

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

• Now you can use the ladybug or turtle cutouts to demonstrate how the numbers go down.
• Practice counting backwards with the students from 10-0.
• Take out the worksheet and read the instructions on it.
• Explain how to cross out the correct number of bugs to get the answer.
• Write the answer in the blank space provided after the subtraction problem.

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

• Allow the children to work in a group with help from you.
• Place your students in small groups, and hand each group one set of the cutouts.
• Show them how to lay down the cutouts, count, and then take away a few and count again.
• Provide a copy of the worksheet inside a sheet protector and a dry erase marker.
• Help the students do the worksheet in a group and write their answers on the sheet protector with the dry erase marker.

### Independent Working Time (10 minutes)

• Once the students have done the activity, collect all the material.
• Give each student a copy of the worksheet and ask them to take out their pencils and crayons.
• Do a quick review of the directions to complete the worksheet.
• Encourage them to start doing their worksheet independently.
• Provide assistance and support when needed.

## Extend

### Differentiation

• Enrichment: Advanced students can do the worksheet and write the numbers on their own.
• Support: Students can trace after you have written the numbers for them. However, encourage them to answer the problems before writing the answers.

## Review

### Assessment (10 minutes)

• Track the time taken by your students to complete the worksheet.
• See if there are lot of questions being asked as they work independently.
• Observe students as they work, and see if you need to do the activity again for better comprehension.

### Review and Closing (5 minutes)

• After the worksheets are completed, collect them.
• Review the lesson's main concepts once more.
