Step 1

Warm-Up: Number Detectives (5 minutes)

5 minutes

Begin with the Place Value Power-Up Warm-Up to get students counting and identifying quantities.
Display images with varying numbers of objects (e.g., 12 stars, 25 circles).
Ask students to write the total number on their whiteboards.
Discuss answers as a class, encouraging students to explain how they counted.

Step 2

Introduction to Place Value (7 minutes)

7 minutes

Use the Place Value Power-Up Slide Deck and Place Value Power-Up Script to introduce place value.
Slide 1: Title Slide - Engage students with the exciting title.
Slide 2: What is Place Value? - Define place value as the value of a digit based on its position.
Slide 3: Tens and Ones - Introduce tens and ones places using visuals (e.g., ten fingers, single blocks).
Slide 4: Meet the Base-Ten Blocks! - Show a 'tens rod' and a 'ones unit' and explain their value. Distribute base-ten blocks to students.
Model how to represent simple numbers (e.g., 13, 21) using base-ten blocks, explicitly pointing out the tens and ones.

Step 3

Guided Practice: Build It, Break It! Activity (10 minutes)

10 minutes

Introduce the Build It, Break It! Activity Cards.
Explain that students will pick a card with a two-digit number.
In pairs or small groups, students will use their base-ten blocks to 'build' the number (e.g., for 34, they'd use 3 tens rods and 4 ones units).
Then, they will 'break it' down by identifying how many tens and how many ones are in the number.
Circulate to provide support and assess understanding. Have students complete the Place Value Practice Worksheet as they work through the cards or as a follow-up.

Step 4

Game: Place Value Scavenger Hunt (5 minutes)

5 minutes

Explain the Place Value Scavenger Hunt Game.
Students will find hidden number cards around the room.
When they find a card, they will identify the number of tens and ones.
The first team/student to correctly identify the tens and ones for all found cards wins (or simply complete the activity).
This can be a quick informal assessment.

Step 5

Wrap-Up & Assessment (3 minutes)

3 minutes

Briefly review the concepts of tens and ones.
Administer the Place Value Check-Up Quiz to assess individual understanding.
Collect quizzes. Use the Place Value Rubric and Place Value Answer Key for grading.

Slide Deck

Place Value Power-Up!

Understanding Tens and Ones!

Welcome students and introduce the exciting topic. Ask them what numbers they know and use every day.

What is Place Value?

It's all about a digit's 'spot' in a number!

Each digit has a special place, and that place tells us its value.

Explain that place value tells us how much each digit in a number is worth. It's like a secret code for numbers!

Meet the Tens and Ones!

Today, we're focusing on two super important places:

ONES Place: This is for single items (0-9).
TENS Place: This is for groups of ten!

Introduce tens and ones. Use your fingers to show 10 (tens) and then one finger (ones). Draw stick figures of 10 and then single dots.

Our Super Tools: Base-Ten Blocks!

We'll use special blocks to help us see place value:

Ones Unit: Looks like a small square. It counts as 1.
Tens Rod: Looks like a long stick. It's made of 10 ones, so it counts as 10!

Show the physical base-ten blocks (if you have them) or pictures. Hand out individual sets or show the printable cut-outs.

Let's Build a Number!

How would we show the number 13?

How many tens do we need?
How many ones do we need?

(Show 1 tens rod and 3 ones units)

Model with an example. Ask students to build 13 with their blocks. Show them 1 tens rod and 3 ones units. Do another example like 21 or 30.

Time for an Activity!

You're going to be Place Value Builders!

We will use our Build It, Break It! Activity Cards to practice building numbers with tens and ones.

Explain that students will be working with activity cards to practice building and breaking numbers. Refer them to the Build It, Break It! Activity.

Game Time: Scavenger Hunt!

Get ready for a Place Value Scavenger Hunt!

Find numbers around the room and figure out their tens and ones!

Explain the game rules. Emphasize teamwork and careful counting.

You're Place Value Pros!

Today, you learned all about tens and ones!

Now, let's show what you know with a quick Place Value Check-Up Quiz!

Remind students what they learned. Hand out the quiz and wish them luck.

Warm-Up: Number Detectives (5 minutes)

"Good morning, future mathematicians! Today we're going on an exciting journey to become 'Number Detectives'! We'll start with a quick warm-up. I'm going to show you some pictures with objects. Your job is to count how many objects you see and write the number on your whiteboard. Ready?"

(Display images with 12 stars, then 25 circles - one at a time. After each, allow time for students to count and write.)

"Alright, let's see for the stars... how many did you count? [Call on a student]. Great! How about the circles? [Call on another student]. Fantastic counting everyone! Keep those number detective skills sharp, because we're going to use them today!"

"Welcome to Place Value Power-Up! Today we're going to unlock a super important secret about numbers. It's going to make understanding big numbers so much easier!"

(Display Place Value Power-Up Slide Deck - Slide 2: What is Place Value?)

"Has anyone ever heard the words 'place value' before? [Pause for responses]. That's okay if not! Place value sounds like a big fancy term, but it just means that each digit in a number has a special 'spot' or 'place,' and that place tells us how much that digit is worth. It's like every number has its own address, and that address tells us important information."

(Display Place Value Power-Up Slide Deck - Slide 3: Meet the Tens and Ones!)

"Today, we're going to become experts on two very important 'places' in numbers: the ONES place and the TENS place.

The ONES place is for single items, like counting one cookie, two cookies, up to nine cookies. It's about 'how many single things' we have.
The TENS place is for groups of ten! Think about when you count your fingers – you have ten fingers, right? That's one group of ten! If you had two friends, you'd have two groups of ten fingers, or twenty fingers!"

(Display Place Value Power-Up Slide Deck - Slide 4: Our Super Tools: Base-Ten Blocks!)

"To help us see and understand tens and ones, we have some special tools called Base-Ten Blocks! (Hold up a ones unit and a tens rod). Can everyone see these?

This small block is a ones unit. It counts as 1.
And this longer stick is a tens rod. It's actually made up of 10 little ones stuck together! So, it counts as 10.

(Distribute base-ten blocks to students or groups, or ensure they have access to printable cut-outs.)

"Now you have your own base-ten blocks! Let's try to build some numbers!"

(Display Place Value Power-Up Slide Deck - Slide 5: Let's Build a Number!)

"How would we show the number 13 using our blocks? Think about it: How many groups of ten do we have in 13? And how many single ones do we have left over?

[Pause for students to think and try to build.]

"That's right! In the number 13, the '1' is in the tens place, so it means one group of ten (one tens rod). And the '3' is in the ones place, so it means three single ones (three ones units). One ten and three ones makes 13! Let's try one more: How would you build the number 21? [Allow time, then model: two tens rods, one ones unit.] Excellent!"

Guided Practice: Build It, Break It! Activity (10 minutes)

(Display Place Value Power-Up Slide Deck - Slide 6: Time for an Activity!)

"You are all doing a fantastic job! Now, we're going to do an activity called 'Build It, Break It!' I have these Build It, Break It! Activity Cards. Each card has a number. You will pick a card, and then use your base-ten blocks to 'build' that number. For example, if your card says 34, you would build it with 3 tens rods and 4 ones units.

"Then, you're going to 'break it' by telling me (or your partner) how many tens and how many ones are in your number. You will also write this down on your Place Value Practice Worksheet. I'll be walking around to help and see all the great building you're doing. Let's start!"

(Circulate, providing support and checking for understanding. After about 8 minutes, bring the class back together.)

"Great work building and breaking those numbers! I saw some amazing place value skills out there! Now, let's get ready for a fun game!"

Game: Place Value Scavenger Hunt (5 minutes)

(Display Place Value Power-Up Slide Deck - Slide 7: Game Time: Scavenger Hunt!)

"It's time for a Place Value Scavenger Hunt! I've hidden some number cards around the room. Your mission, should you choose to accept it, is to find a card, look at the number, and then tell me (or write down) how many tens and how many ones are in that number. You can work with a partner for this. When you find a card, bring it back to your seat and figure out the tens and ones. Ready, set, HUNT!"

(Monitor students during the game. This can be a quick, informal check.)

Wrap-Up & Assessment (3 minutes)

(Display Place Value Power-Up Slide Deck - Slide 8: You're Place Value Pros!)

"Wow, you all were amazing place value detectives and builders today! We learned that numbers are made of tens and ones, and their 'place' tells us their value. To show me what you've learned, I'm going to hand out a quick Place Value Check-Up Quiz.

"Please do your best on this quiz. When you're done, turn it in to the basket. You've got this!"

(Distribute quizzes. Collect them as students finish. End of lesson.)
