The image you've uploaded shows a table of contents from a mathematics textbook, specifically
Unit 1: Place Value and Whole Number Operations. This unit is divided into two modules:
---
Module 1: Place Value of Whole Numbers
-
Lesson 1: Understand Place Value Relationships — Page P1
-
Lesson 2: Read and Write Numbers — Page P3
-
Lesson 3: Regroup and Rename Numbers — Page P5
-
Lesson 4: Compare and Order Numbers — Page P7
-
Lesson 5: Use Place Value Understanding to Round Numbers — Page P9
This module focuses on building foundational skills in understanding how digits in numbers represent different values based on their position (e.g., ones, tens, hundreds, etc.), reading and writing numbers correctly, regrouping (like in addition or subtraction), comparing numbers, and rounding.

Module 2: Addition and Subtraction of Whole Numbers
-
Lesson 1: Add Whole Numbers and Assess Reasonableness — Page P11
-
Lesson 2: Subtract Whole Numbers and Assess Reasonableness — Page P13
-
Lesson 3: Use Addition and Subtraction to Solve Comparison Problems — Page P15
-
Lesson 4: Apply the Perimeter Formula for Rectangles — Page P17
This module moves on to operations with whole numbers, teaching students how to add and subtract efficiently, check if their answers make sense (reasonableness), solve word problems involving comparisons, and apply arithmetic to geometry—specifically calculating the perimeter of rectangles using the formula:
$$
\text{Perimeter} = 2 \times (\text{length} + \text{width})
$$
---
Summary:
This unit is designed to strengthen students' understanding of
place value, which is essential for performing accurate calculations. It then builds on that foundation by teaching
addition and subtraction of whole numbers and applying these skills to real-world problems, including geometry.
If you have a specific problem or question related to any of these lessons (e.g., "How do I round a number?" or "What is the perimeter of a rectangle?"), feel free to ask!
