Place Value Block Party!

Materials Needed:

• LEGOs or other building blocks (at least 3 colors)
• Large sheet of paper or a small whiteboard & markers
• A place value mat (a sheet of paper divided into three columns: HUNDREDS | TENS | ONES)
• Index cards or small pieces of paper
• A small bag or box
• Upbeat music for the warm-up activity

Lesson Plan Details

1. Learning Objectives

By the end of this lesson, Brandon will be able to:

• Identify the value of each digit in a three-digit number (hundreds, tens, ones).
• Understand that a "hundred" is a bundle of ten "tens."
• Read and write numbers up to 1,000 in standard form, word form, and expanded form.
• Skip-count by 5s, 10s, and 100s.

2. Relevant Standards (Georgia Standards of Excellence)

• MGSE2.NBT.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones.
• MGSE2.NBT.1.a: Understand that 100 can be thought of as a bundle of ten tens — called a “hundred.”
• MGSE2.NBT.2: Count within 1000; skip-count by 5s, 10s, and 100s.
• MGSE2.NBT.3: Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

Lesson Activities

Part 1: Warm-Up - Skip-Counting Dance! (5 minutes)

Goal: To get energized and practice skip-counting (MGSE2.NBT.2).

1. Turn on some fun, upbeat music.
2. Call out a starting number and what to skip-count by. For example, "Let's skip-count by 10s starting at 0!"
3. Brandon will dance around while counting aloud: "10, 20, 30, 40, 50..."
4. Switch it up! Try counting by 5s (5, 10, 15...), and then by 100s (100, 200, 300...). This is a great physical way to feel the rhythm of numbers.

Part 2: Building Our Numbers - The LEGO System (10 minutes)

Goal: To create a concrete, hands-on understanding of place value (MGSE2.NBT.1, MGSE2.NBT.1.a).

1. Establish the Rules: On the whiteboard, draw a key for the LEGO blocks.
   • A single block (e.g., blue) = 1 ONE
   • A pre-built stick of 10 blocks (e.g., yellow) = 1 TEN
   • A pre-built flat of 10 ten-sticks (e.g., red) = 1 HUNDRED
2. The Ten Trade: Have Brandon count out 10 single "one" blocks. Then, show him how he can "trade" those 10 ones for one "ten" stick. Reinforce: "10 ones make 1 ten."
3. The Hundred Trade (Key Concept!): Line up 10 "ten" sticks. Have Brandon skip-count them by 10s: "10, 20, 30... 100!" Then, show him how he can "trade" those 10 tens for one "hundred" flat. State clearly: "10 tens make a bundle we call a hundred." (This directly addresses MGSE2.NBT.1.a).

Part 3: Guided Practice - Build-A-Number (15 minutes)

Goal: To practice building and writing numbers in different forms with support (MGSE2.NBT.1, MGSE2.NBT.3).

1. Lay out the "HUNDREDS | TENS | ONES" place value mat.
2. Call out a three-digit number, for example, 254.
3. Work with Brandon to build the number on the mat using the LEGOs:
   • "How many hundreds do we need?" (He places 2 red "hundred" flats in the hundreds column).
   • "How many tens?" (He places 5 yellow "ten" sticks in the tens column).
   • "And how many ones?" (He places 4 blue "one" blocks in the ones column).
4. Next, on the whiteboard, write the number together in three ways:
   • Standard Form (The Number): 254
   • Word Form (The Name): two hundred fifty-four
   • Expanded Form (The Value): 200 + 50 + 4
5. Repeat with 2-3 more numbers, making sure to include one with a zero, like 309, to emphasize that the zero is a placeholder.

Part 4: Independent Application - Place Value Secret Agent (15 minutes)

Goal: To apply all the learned concepts creatively and independently.

1. The Mission Briefing: "Secret Agent Brandon, your mission is to decode the secret number hidden in this bag!"
2. Secretly place a collection of LEGOs into the bag (e.g., 3 hundred-flats, 7 ten-sticks, and 2 one-blocks).
3. Brandon pours out the bag, sorts the blocks by type (hundreds, tens, ones) onto his place value mat, and determines the total number.
4. He then fills out a "Secret Agent Report" on an index card:
   • Secret Number (Standard Form): 372
   • Code Name (Word Form): three hundred seventy-two
   • Deconstructed Value (Expanded Form): 300 + 70 + 2
5. Repeat with a new secret number if time allows.

Part 5: Wrap-Up & Assessment - Stump the Teacher! (5 minutes)

Goal: A fun, low-pressure way to assess Brandon's understanding.

1. Flip the roles! It's Brandon's turn to be the Mission Commander.
2. He creates a secret number by putting LEGOs in the bag.
3. He gives the bag to you. You then sort the blocks and write the number in all three forms on the whiteboard.
4. Brandon's job is to check your work and confirm if you cracked his code correctly. This empowers him and reveals his level of mastery in a playful way.

Differentiation & Extension

• For Extra Support: If three digits are overwhelming, start with two-digit numbers (tens and ones) and work your way up. Use pre-written cards for the word form if spelling is a challenge.
• For an Extra Challenge: Ask questions like, "What if you had 12 ten-sticks? What could you trade them for?" to introduce the concept of regrouping. Or, give him three number cards (e.g., 8, 2, 5) and ask him to build the largest possible number (852) and the smallest possible number (258).
