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