Place Value Power-Up!

Emily Parker

Tier 1
For Schools

Lesson Plan

Place Value Power-Up!

Students will be able to identify the place value of digits (ones, tens, hundreds) in a three-digit number using visual and hands-on methods.

Understanding place value helps us make sense of numbers, count money, and solve everyday math problems. It's a fundamental skill for all math learners!

Audience

Autistic Middle School Students

Time

20 minutes

Approach

Visual, kinesthetic, and interactive learning.

Materials

Whiteboard or projector, Warm-Up: Number Hunt!, Place Value Slides, Base-ten blocks (or printed cut-outs), Place Value Match-Up Activity, and Place Value Practice Worksheet

Prep

Teacher Preparation

10 minutes

  • Review all generated materials: Place Value Power-Up! Lesson Plan, Warm-Up: Number Hunt!, Place Value Slides, Place Value Match-Up Activity, and Place Value Practice Worksheet.
  • Gather base-ten blocks (or print and cut out the included base-ten block templates).
  • Ensure projector/whiteboard is ready for the Place Value Slides.
  • Print copies of the Warm-Up: Number Hunt! and Place Value Practice Worksheet.

Step 1

Warm-Up: Number Hunt! (3 minutes)

3 minutes

  • Distribute the Warm-Up: Number Hunt!.
  • Teacher Script Suggestion: "Let's start with a quick game! Look around the room. Can you find numbers? On the clock, a book, a poster? Write down one number you see and tell me what it is."
  • Allow students to share one number they found. Keep it quick and fun.

Step 2

Introduction to Place Value (5 minutes)

5 minutes

  • Display Slide 1: What is Place Value? and Slide 2: Our Number System.
  • Teacher Script Suggestion: "Today we're going to become 'Number Detectives'! We're going to discover a secret about numbers – how much each digit is worth based on where it sits. It's like a number's 'address'!"
  • Introduce ones, tens, and hundreds using Slide 3: Ones, Tens, Hundreds and base-ten blocks.
  • Teacher Script Suggestion: "Look at these blocks! A small cube is 1 'one'. A long stick is 10 'tens'. A big flat square is 100 'hundreds'. We'll use these to build numbers!"

Step 3

Hands-On Activity: Place Value Build (7 minutes)

7 minutes

  • Display Slide 4: Build a Number!.
  • Distribute base-ten blocks to students.
  • Teacher Script Suggestion: "Now, let's build some numbers together! I'll say a number, and you show it with your blocks. Let's try 34. How many tens? How many ones?" (Guide students to use blocks).
  • Repeat with a few more numbers, gradually increasing difficulty, e.g., 52, 125, 207.
  • Teacher Script Suggestion: "Great job! Each block shows us the value of the number in its 'place'."

Step 4

Practice with Worksheet (5 minutes)

5 minutes

  • Distribute the Place Value Practice Worksheet.
  • Display Slide 5: Time to Practice!.
  • Teacher Script Suggestion: "Now it's your turn to be a 'Place Value Master' on your own! Look at the numbers on your worksheet. Circle the digit in the tens place, or write how many hundreds you see. Do your best!"
  • Circulate to provide individual support and clarification as needed, especially for students with limited reading skills. Focus on the visual cues and verbal instructions.

Slide Deck

Place Value Power-Up!

Become a Number Detective!
Discover the secret power of numbers!

Welcome students and set an exciting tone. Explain that they will be like 'Number Detectives' today.

What is Place Value?

Each number has a special 'job'!
Its 'job' changes depending on its 'address'!

Introduce the concept of place value as a number's 'address' or 'job'. Emphasize that each digit has a different value depending on its position.

Ones, Tens, Hundreds

Ones (1)

  • Smallest blocks, stand for 1

Tens (10)

  • Long blocks, stand for 10

Hundreds (100)

  • Flat squares, stand for 100

Introduce ones, tens, and hundreds using base-ten blocks as visual aids. Hold up each block type as you explain.

Build a Number!

Let's build numbers with our blocks!

  1. Teacher says a number.
  2. You show it with blocks!

Example: 34 (3 tens, 4 ones)
Example: 125 (1 hundred, 2 tens, 5 ones)

Guide students through building numbers with their base-ten blocks. Start with two-digit numbers and move to three-digit numbers. Provide direct instructions and positive reinforcement.

Time to Practice!

Show what you know!

  • Look at the numbers.
  • Circle the tens place.
  • Write the value of the hundreds.

Explain that students will now work on their worksheets. Reiterate instructions visually if possible, pointing to sections of the worksheet.
