New MathReps Available in Snorkl Library
It’s been a crazy summer. In the last post, I talked about MathReps living in the Snorkl App – a sampling of MathReps, not the full collection. Well, I’m proud to say that they ARE indeed up and ready for you to use. Currently, K-2 is live with others being added regularly. The plan is to have a sampling from K through high school available.
So, where might you find them on the website? I’m so glad you asked. Log in to Snorkl App. Once logged in, navigate to the ‘Library’ tab. Click on the down arrow and select ‘Snorkl Library’.
Once in the Snorkl Library, navigate to the ‘General’ section. That’s where you’ll find MathReps.
That’s right, you’ll see 37 ready-to-use MathReps! Snorkl will continue to add to them as they are ready. 3rd-grade is in the works as I write this. If you have any questions or requests, please feel free to reach out, and I’m happy to help.
MathReps & Snorkl
Oofta, it’s been a hot minute. I’d like to blame end-of-the-year craziness on my lack of posting, but that’s not the whole story. The other part is that I just haven’t been motivated. Welp, I’m back!
Today, I’d like to briefly touch on a new(ish) app – Snorkl. This tool utilized AI in the best way. Students record their work via screen recording, voice and screen recording, only audio, or written. I have been focusing on the voice and screen recordings. This quick video shows how I built out a 1st-grade MathRep and how students can show their work. I know, you’re thinking, “So where is the AI?” So glad you had that thought; it comes in the form of immediate feedback in this case. It’s so much easier if I show you:
So what are your thoughts? How can you see utilizing Snorkl in your classroom?
Effective Place Value Techniques for Teaching Addition
Are you looking for a way to help students truly see what’s happening when they add multi-digit numbers? One powerful approach uses place value-based strategies that build from representational thinking toward more efficient, abstract methods.
Start with Expanded Form
In the first part of the video, I model a place value strategy using expanded form. Students break apart each number into hundreds, tens, and ones, add those values separately, and then combine their sums.
This representational method supports flexible thinking and strengthens their understanding of how numbers work. It also lays a strong foundation for future strategies that depend on place value fluency.
Scaffold Toward the Algorithm
Next, I introduce a slightly more advanced approach that continues to use the Hundreds Chart as a scaffold. This visual support helps students begin to internalize regrouping and transitions them toward the traditional addition algorithm, a 4th-grade standard.
This shift is intentional. By gradually moving from expanded form to a structure that supports the algorithm, students develop a deeper understanding of why the algorithm works—not just how to use it.
Support with Consistent Structure
The real power of MathReps lies in their consistency. Each template reinforces key math skills in a familiar format, allowing students to focus on developing strategies and precision rather than navigating new instructions each time.
Whether students are practicing during warm-ups, small groups, or independent work, MathReps create a rhythm of reflection and growth with immediate feedback.

Experiencing MathReps Success at Cipriani Elementary
A few weeks ago, I had the absolute pleasure of visiting Cipriani Elementary School in Belmont, California, and let me tell you—it was a fantastic day that filled my heart.
Throughout the day, I was met with warm smiles, welcoming teachers, and the most amazing group of students. I had the opportunity to visit several classrooms ranging from TK through fifth grade, and in each room, I was able to demonstrate MathReps and watch in amazement as students flourished in their math knowledge.
What stood out most to me during these classroom visits was the level of engagement and understanding the students displayed. They were respectful, kind, curious, and so eager to learn. It’s one thing to talk about the power of MathReps—but it’s another thing entirely to see it in action in so many classes.
The Cipriani staff was incredible. Not only were they open and receptive, but they also shared their own tips and tricks for how they modify and adapt MathReps to meet the needs of their students. I was genuinely inspired by the way they’ve made the framework their own. I came to share—but I left having learned so much from them too. That kind of collaborative energy is what makes this work so meaningful.
One of my favorite moments from the day happened in a third-grade classroom. As I was working with the students, one of them looked up at me, wheels turning in their head, and said, “Wait… your name is on the bottom of our MathReps!” The class instantly lit up with excitement. Then they asked, “Did you also make Math Dash Chats?” When I said yes, the energy doubled. That little moment of connection—of realizing that the person who created something they use every day was standing right there with them—was truly special. It reminded me that kids are paying attention, even when we don’t think they are.
Later that afternoon, I led a Math 360 professional development session with the entire staff. Thanks to our friends at Wipebook, we had large Wipebook flip charts to work with, and it made the experience even more interactive and fun. The discussions were rich and reflective, and once again, the Cipriani teachers brought their full selves to the table—asking great questions, sharing insights, and showing a genuine passion for improving math instruction.
Overall, it was such a rewarding, joy-filled day. I left Cipriani Elementary feeling deeply grateful—and even more motivated to continue visiting classrooms across the country to share the love, importance, and power of MathReps.
I am thankful to everyone at Cipriani Elementary for making me feel so welcome.

Understanding Subtraction with Pictorial and Expanded Models
Why Use Multiple Models?
By using a pictorial model alongside expanded notation, students get a visual and numeric understanding of subtraction. This helps them move beyond memorized procedures to truly grasp why and how regrouping works.
Let’s break it down step by step!
Step 1: Set Up the Problem
We’re working with 736 – 274.
- 736 is represented using pictorial models in a place value chart:
- 7 hundreds
- 3 tens
- 6 ones
- Below, we note in the corner of each place value column what we’re subtracting: 200 + 70 + 4 = 274
Step 2: Subtract Using the Pictorial Model
Subtract the Ones (6 – 4):
- Cross off 4 ones (I like to use x to represent 1s).
- That leaves 2 ones.
Regroup the Tens (30 – 70):
- Uh-oh! We don’t have enough tens to subtract 70.
- So, we regroup 100 into 10 tens (since 100 = 10 tens).
- Now, we have 13 tens total (13 tens = 130)
- We subtract 70 (or 7 tens) from 13 tens, leaving 6 tens (or 60).
Subtract the Hundreds (700 – 200):
- After regrouping, we have 600 left in the hundreds place.
- Subtracting 200 leaves us with 400.
Final Answer: 462
Step 3: Solve Using Base 10 Expanded Notation
Now, let’s represent the numbers in expanded form:
- 736 → 700 + 30 + 6
- 274 → 200 + 70 + 4
Subtracting step-by-step:
- 6 – 4 = 2
- 30 – 70 (not possible, so we regroup from the hundreds)
- Moving 100 over to the 10s place, making it 130 – 70 = 60
- 600 – 200 = 400
Final Answer: 462
The Power of Dual Modeling
Using both pictorial and expanded form models side by side helps students see:
✏️ Why we “regroup” in subtraction
✏️ How place value plays a role in regrouping
✏️ That both methods lead to the same solution, reinforcing accuracy
When students see and practice both models together, they build deeper number sense and mathematical confidence!

Effective MathReps for Addition with Regrouping
Today, we’re diving into second-grade math with a MathRep that focuses on addition with regrouping.
In our previous posts, we explored using MathReps for addition and subtraction without regrouping. Now, we’re taking it a step further and tackling regrouping, helping students make the jump from pictorial models to expanded notation and the base 10 system.
So, buckle in—let’s get started!
Step-by-Step Guide: Regrouping with MathReps
Set Up the Numbers
For this example, we’re adding 682 + 234, and we’ll use a pictorial model to visually represent the numbers before transitioning into the expanded form.
Solve Using a Pictorial Model
1️⃣ Start with the Ones Place:
- 2 + 4 = 6
- No regrouping needed here, so we write 6 in the ones place.
2️⃣ Move to the Tens Place:
- We add 8 tens + 3 tens = 11 tens, which equals 110.
- Since 10 tens = 100, we regroup by circling ten tens and moving them into the hundreds place.
- This leaves 1 ten (10) in the tens place.
3️⃣ Move to the Hundreds Place:
- We now have 6 hundreds + 2 hundreds + 1 regrouped hundred = 9 hundreds.
Bringing it all together:
916
Transition to the Base 10 Model (Expanded Notation)
Now, let’s break it down using expanded form:
- 682 → 600 + 80 + 2
- 234 → 200 + 30 + 4
Adding the place values:
- Ones: 2 + 4 = 6
- Tens: 80 + 30 = 110 → Regroup into 100 + 10
- Hundreds: 600 + 200 + 100 = 900
Total: 916
Alternative Thinking: Flexible Number Sense
Instead of regrouping immediately, students can leave the tens as 110 and think of the sum as:
800 + 110 + 6 = 916
This approach challenges students to see numbers flexibly before applying the standard algorithm, deepening their conceptual understanding.
Why This Works
MathReps provide a structured, visual approach that helps students bridge the gap between pictorial models and formal mathematical notation. By working through regrouping in different ways, students develop number flexibility and problem-solving confidence.

Subtraction Made Simpler With MathReps
I’m here to show you how MathReps can make subtraction practice easier and more engaging for your students. In our last post, we explored how to use a MathRep for addition, and today, we’ll focus on subtraction.
This step-by-step guide will show you how to use the MathRep template in your classroom, helping students bridge the gap between visual models and abstract concepts.
Set Up the Numbers
For this example, we’ll work with 658 and 234. The subtraction problem is set up in a pictorial model, where the number 658 is represented visually, and 234 is broken down into ones, tens, and hundreds to subtract from each place value.
Use a Pictorial Model to Subtract
In the pictorial model, each section represents a place value: ones, tens, and hundreds.
- Subtract the ones:
- Start with 8 ones and subtract 4.
- Cross out or erase 4 ones, leaving 4 ones.
- Subtract the tens:
- Start with 50 tens and subtract 30 (3 groups of ten).
- Cross out 3 groups, leaving 20 tens.
- Subtract the hundreds:
- Start with 600 hundreds and subtract 200 (2 groups of 100).
- Cross out 2 groups, leaving 400 hundreds.
Combine the remaining values:
400 + 20 + 4 = 424
Transition to the Base 10 Model
Now, transfer the pictorial model into a base 10 model by writing the numbers in expanded form:
- 658 → 600 + 50 + 8
- 234 → 200 + 30 + 4
Follow the same subtraction process:
- Subtract the ones: 8 – 4 = 4
- Subtract the tens: 50 – 30 = 20
- Subtract the hundreds: 600 – 200 = 400
Bring it all together:
400 + 20 + 4 = 424
Why This Works
This activity helps students make meaningful connections between the pictorial model and the base 10 system, reinforcing their understanding of subtraction and place value. By bridging these two models, students gain confidence in solving subtraction problems and build a deeper understanding of the math concepts.

I’m excited to share how MathReps can transform daily math practice into a fun and engaging activity for your students. Whether you’re a seasoned teacher or just starting your journey, MathReps are a fantastic tool to build fluency and confidence in math concepts.
For today’s demonstration, let’s dive into a 2nd-grade MathRep and explore how you can use it in your classroom. This template can also be found on Wipebook Workbooks and Kami!
Step-by-Step Guide: Using MathReps in Your Classroom
1. Set Up the Numbers
For this example, we’re working with 237 and 422. Begin by deciding whether your students will add or subtract these numbers. For this demonstration, we’ll focus on addition.
2. Use a Pictorial Model
Start by setting up the numbers in a pictorial model.
- Creating a 100’s chart will help students represent each digit in the numbers.
- Each x will represent the ones (I prefer x’s over dots as it can become hard to distinguish individual dots)
- Each l will represent the tens
- Each square will represent the hundreds
- Count the ones, tens, and hundreds in each number:
- Ones: 7 ones + 2 ones = 9 ones
- Tens: 30 tens + 20 tens = 50 tens
- Hundreds: 200 hundreds + 400 hundreds = 600 hundreds
Add these values together:
659
3. Transition to the Base 10 Model
Once students understand the pictorial model, encourage them to transfer the information to a base 10 model by breaking down the numbers into expanded form:
- 237 → 200 + 30 + 7
- 422 → 400 + 20 + 2
Have the students add the expanded forms:
- Add the ones: 7 + 2 = 9
- Add the tens: 30 + 20 = 50
- Add the hundreds: 200 + 400 = 600
Bring it all together:
600 + 50 + 9 = 659
Why It Works
This activity bridges the gap between pictorial models and abstract math concepts. Students not only practice addition but also develop a deeper understanding of place value and number decomposition.
