Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Grades K-2 (Ages 5-8)

Length of Lesson

30 minutes

Number of Students

20

Objectives

• Understand the concept of base ten and why it is essential in mathematics.
• Identify and manipulate base ten blocks to represent numbers.
• Develop skills in addition and subtraction using base ten principles.

Materials

• Base ten blocks (units, rods, and flats)

National Curriculum Alignment

This lesson aligns with the following Common Core State Standards for Mathematics:

• CCSS.MATH.CONTENT.K.NBT.A.1: Compose and decompose numbers from 11 to 19 into ten ones and some additional ones.
• CCSS.MATH.CONTENT.1.NBT.B.2: Understand that the two digits of a two-digit number represent amounts of tens and ones.
• CCSS.MATH.CONTENT.2.NBT.B.5: Fluently add and subtract within 100.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Base Ten	5 min	Introduce the concept of base ten. Discuss the significance of grouping by tens. Show base ten blocks.
2	Demonstration	10 min	Demonstrate how to use base ten blocks to represent different numbers. Use whiteboard for visual aid.
3	Guided Practice	5 min	Provide students with a few sample numbers to represent using base ten blocks while providing support.
4	Independent Practice	5 min	Hand out worksheets with problems related to base ten. Students solve with minimal guidance.
5	Review and Conclusion	5 min	Summarize key points of the lesson, address any misconceptions, and prepare students for the homework assignment.

Homework

Give students a worksheet that includes various base ten problems. Review the completed homework in the next class without requiring students to present their work publicly. Provide feedback through written comments.

Assessment

• Observe student participation during guided practice.
• Review completed worksheets to gauge understanding of base ten.
• Use informal assessment through questioning during the lesson and clarify any concepts as needed.

Additional Notes

• Be mindful of different student learning styles; provide extra assistance to those who need it.
• Encourage collaboration by allowing students to discuss their answers with a partner if time permits during independent practice.
