Foundational Math Skills
Welcome students and introduce the concept of place value as the 'value of where a digit sits'. Emphasize that numbers are made up of digits, and their position matters.
What's a Digit Worth?
Numbers are made of digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
The place a digit is in tells us its value
We'll start with ones and tens !
42
Ones Place: The Single Digits
The very first digit on the right is the ones place .
It tells you how many single items you have.
Example: In the number 5 , you have 5 ones.
Tens Place: Groups of Ten
The digit to the left of the ones place is the tens place .
It tells you how many groups of ten you have.
In 43 , the 4 is in the tens place (40) and 3 is in the ones place (3).
1 Ten = 10 Ones
Going Bigger: The Hundreds Place
To the left of the tens place is the hundreds place .
Example: In the number 3 00, the 3 is in the hundreds place.
You have 3 groups of one hundred!
What's the Value?
In 123...
What is the value of the 1?
(100)
In 456...
What is the value of the 5?

Adding It Up: Within 10
Addition means combining or putting things together.

Taking It Away: Within 10
Subtraction means taking away or finding the difference.

Week 1: Foundations of Place Value
Session 1: What's a Digit Worth? (Slides 1-3)
Teacher: "Good morning/afternoon, everyone! Today, we're going on an adventure to understand how numbers work. It's like finding out a superhero's secret identity! Every number has parts called digits . Can you say 'digits'?"
Teacher: "Excellent! Digits are the single numbers from 0 to 9. And where a digit sits in a number tells us how much it's worth. This is called place value ." [Show Slide 1]
Teacher: "Let's start with the easiest place, the ones place . This is the very first spot on the right side of a number. It tells us how many single items we have. If I show you 5 blocks, the digit '5' is in the ones place." [Show Slide 2. Model with physical blocks.]
Teacher: "Now, the tens place . This is just to the left of the ones. It tells us how many groups of ten we have. If I have 2 groups of ten, that's 20! In the number 43, what digit is in the tens place?" [Show Slide 3]
Session 2: Digits Up to 100s (Slides 4-6)
Teacher: "Welcome back! Today, we're going even bigger! We're adding the hundreds place . This is to the left of the tens place, and it tells us how many groups of one hundred we have." [Show Slide 4]
Teacher: "Let's practice! If I show you the number 123, what is the value of the '1'? What about the '2'? Remember, the position gives the power!" [Show Slide 5]
Week 2: Operations & Intro to Word Problems
Session 6: Word Problems - Addition (Slides 13-15)
Teacher: "Get ready for story time, math style! We're going to learn about word problems . These are like little math stories, and our job is to figure out what the story wants us to do!" [Show Slide 13]
Teacher: "Look at this: 'Sara has 23 apples. Tom gives her 15 more.' What are the important numbers? What is the clue word? 'More' means ADD!" [Show Slide 14]
Session 7: Adding with Regrouping (Slides 16-18)
Teacher: "Sometimes when we add, the ones column gets too full! It gets to 10 or more. When that happens, we trade 10 ones for 1 ten. It's called regrouping ." [Show Slide 16. Use base-ten blocks.]

How to Play
Preparation: Cut out the Number Cards and Value Cards below. Shuffle them separately.Objective: Match each Number Card to the correct Value Card (e.g., 25 matches "2 tens, 5 ones").Individual Play: Lay all cards face up. Pick a number, say it out loud, and find its match.Teacher Support: Ask questions like "How many hundreds are in this number?" to guide the student.
Differentiation
Start Small: Use only tens and ones cards first.Fewer Cards: Start with only 4 pairs to avoid overwhelm.Visual Cues: Point out the colors or use base-ten blocks to help.Expanded Form: Ask students to write the number as an addition problem (e.g., 100 + 30 + 4).

Objective
To encourage students to articulate their strategies for solving word problems and reflect on common challenges and solutions.
Teacher Prompt (2-3 mins)
"You've all been doing amazing work with word problems! Today, we're going to talk about how we solve them. It's like being a detective and figuring out the clues in a math story. Let's see how you solve your cases!"
Key Questions
1. Understanding the Problem
"When you read a word problem, what is the very first thing you try to understand?"
"How do you know what numbers are important in the story?"
"What are some 'clue words' that tell you if you need to add? What about subtract?"
2. Choosing the Operation
"How do you decide whether to add or subtract?"
"For our two-step problems, how do you figure out which step to do first?"
3. Solving and Checking
"What tools or strategies do you use? (drawing pictures, number lines, etc.)"
"After you get an answer, how do you check if it makes sense?"
4. Challenges and Tips
"What is the hardest part about solving word problems for you?"
"What advice would you give to a friend who is struggling with word problems?"
"Thank you for sharing your great ideas! Remember, every word problem is like a puzzle, and you have all the tools to solve it. Keep practicing those detective skills!"
