Title: Introduction to Regrouping for PreK and Kindergarten

Objective: - Introduce the concept of regrouping in a simple and engaging way - Help students understand the concept of regrouping through hands-on activities and visual aids - Develop students’ critical thinking and problem-solving skills

Materials: - Counting manipulatives (e.g., cubes, buttons, or small toys) - Whiteboard or chart paper - Markers or colored pencils - Regrouping visual aids (e.g., pictures or drawings of groups of objects)

Lesson Plan:

1. Introduction (5 minutes):
   • Gather the students in a circle and explain that today they will be learning about a new math concept called “regrouping.”
   • Show them a picture of a group of objects (e.g., five apples) and ask them how many objects they see.
   • Write the number on the whiteboard or chart paper and explain that this is called the “ones” place.
2. Exploring Ones and Tens (10 minutes):
   • Distribute counting manipulatives to each student.
   • Ask the students to count out ten manipulatives and place them in a group.
   • Explain that this group represents the “tens” place.
   • Ask the students to count out five more manipulatives and place them in a separate group.
   • Explain that this group represents the “ones” place.
   • Write the number 15 on the whiteboard or chart paper and explain that it is made up of one group of ten and five ones.
3. Introducing Regrouping (15 minutes):
   • Show the students a picture or drawing of a group of objects, such as 13 apples.
   • Ask the students to count the objects and write the number on the whiteboard or chart paper.
   • Explain that when we have more than ten objects in the ones place, we need to regroup them into a new group of ten.
   • Demonstrate how to regroup by physically moving ten objects from the ones place to the tens place.
   • Write the new number on the whiteboard or chart paper (e.g., 1 ten and 3 ones) and explain that it is the same as 13.
4. Hands-on Regrouping Activity (15 minutes):
   • Divide the students into pairs or small groups.
   • Give each group a set of counting manipulatives and a worksheet with simple addition problems involving regrouping (e.g., 7 + 6).
   • Instruct the students to solve the problems by physically regrouping the manipulatives as needed.
   • Circulate around the room to provide assistance and guidance as necessary.
5. Conclusion (5 minutes):
   • Gather the students back in a circle and review what they have learned about regrouping.
   • Ask them to share any observations or insights they gained from the hands-on activity.
   • Summarize the concept of regrouping and emphasize its importance in understanding place value.
   • Encourage the students to practice regrouping at home with their parents or caregivers.

Note: This lesson is designed to introduce the concept of regrouping in a simplified manner suitable for PreK and Kindergarten students. As they progress in their math education, they will encounter more complex regrouping scenarios.
