Vocabulary
Place Value: The value of a digit depending on its position within a number.
Thousands: A block that represents one thousand units.
Hundreds: A block that represents one hundred units.
Tens: A block that represents ten units.
Ones: A single unit block.
Place Value Pros
Use Place Value Models Up To Thousands
Prerequisite Skill
Materials and Preparation
- Base-ten blocks (thousands, hundreds, tens, and ones)
- Whiteboard and markers
- TeachTastic Worksheet Pack for Place Value Models up to Thousands
- Place value charts
- Number cards (0-9)
Learning Objectives
- Students will be able to identify the value of each digit in a four-digit number using base-ten blocks.
- Students will understand the concept of place value in numbers up to 9,999.
- Students will be able to construct and decompose numbers using base-ten blocks.
Introduction
Begin by showing students a base-ten block representation of a number. Ask, "What number is shown?" Guide them to count the blocks: thousands, hundreds, tens, and ones. Explain how each block represents a different place value. Use an example such as 1,247 to illustrate: 1 thousand block, 2 hundred blocks, 4 ten blocks, and 7 one blocks.
Explicit Instruction/Teacher modeling
Demonstrate how to count the blocks and write the number:
- Count the thousands blocks and write down the number of thousands.
- Count the hundreds blocks and write down the number of hundreds.
- Count the tens blocks and write down the number of tens.
- Count the ones blocks and write down the number of ones. Show multiple examples, each time emphasizing the place value of each digit.
Guided Practice
Hand out the Teach Tastic worksheet pack for place value models up to thousands. Work through two problems as a class. For each problem, present two place value models and ask the question: "Which place value model represents 283?" Provide two models, Version A and Version B, and have students count the blocks for each place value model. Once they have counted, students will announce whether Model A or Model B is the correct representation. Provide support and address any misconceptions as needed.
Independent Practice
Have students complete the remaining problems in the TeachTastic Worksheet Pack independently. Walk around the room to offer help and ensure students are correctly identifying the place values and writing the numbers accurately.
Differentiation
Support
- Provide extra practice with one-on-one or small group instruction using base-ten blocks.
- Use visual aids, such as place value charts and diagrams, to reinforce the concept.
- Offer simplified problems with fewer blocks for students who need additional support.
Extension
- Challenge students to create their own numbers using base-ten blocks and write the corresponding numbers.
- Provide problems involving addition and subtraction of numbers using base-ten blocks.
- Introduce place values beyond thousands, such as ten thousands, for advanced students.
Assessment
Evaluate students' understanding through their work on the worksheet pack and exit tickets. Look for accurate counting of base-ten blocks and correct identification of place values.
Review and closing
Summarize the key points of the lesson: the value of digits in thousands, hundreds, tens, and ones places. Address any common misconceptions and answer any remaining questions. Allow students to share their observations and thoughts on the lesson.
Misconceptions
- Confusing place values: Students might mix up the place values (e.g., thinking a ten block is a hundred block).
- Skipping a place value: Students might forget to count one of the place values, leading to incorrect numbers.
- Incorrect counting: Students might miscount the number of blocks in a given place value.
