Objective

By the end of this lesson, you will be able to understand and apply place value concepts in mathematics.

Materials and Prep

• Pencil
• Blank paper or notebook

No prior knowledge is required for this lesson.

Activities

1. Introduction to Place Value

Start by explaining to the student what place value is. Use examples such as the ones and tens place in a two-digit number to help them understand that the position of a digit determines its value.

2. Place Value Practice

Provide the student with a series of two-digit numbers and ask them to identify the value of each digit. For example, in the number 34, the value of the digit 3 is 30 (thirty) and the value of the digit 4 is 4 (four).

3. Expanded Form

Introduce the concept of expanded form, where each digit in a number is written separately with its corresponding place value. For example, the number 56 can be written as 50 + 6.

4. Expanded Form Practice

Provide the student with a few numbers and ask them to write the expanded form of each number. For example, for the number 42, the expanded form would be 40 + 2.

5. Creating Numbers

Give the student a set of digits (e.g., 2, 4, 6) and ask them to create different two-digit numbers using those digits. Encourage them to explore different combinations and explain the value of each digit in the numbers they create.

First Grade Talking Points

• "Place value helps us understand the value of each digit in a number."
• "The position of a digit in a number tells us its value."
• "The ones place is for single-digit numbers, and the tens place is for numbers with two digits."
• "Expanded form shows each digit in a number separately with its place value."
• "We can create different numbers by using different digits and understanding their values."
