Description
What It Is:
A structured three-digit addition worksheet that uses H-T-O (Hundreds–Tens–Ones) place-value grids. Students add pairs of three-digit numbers vertically and use the extra boxes to show regrouping clearly.
Why Use It:
This worksheet strengthens place-value understanding and helps students practice regrouping (carrying) in three-digit addition. The H-T-O layout visually guides learners to organize digits correctly, reduce errors, and build confidence with more complex addition.
How to Use It:
• Have students add numbers column by column using the H-T-O chart.
• Use the blank bottom row to record regrouped values and final sums.
• Ideal for independent practice, small-group instruction, or homework.
Grade Suitability:
Best suited for Grades 2–4.
• Great for students transitioning from two-digit to three-digit addition.
• Supports learners who need visual scaffolding for regrouping.
Target Users:
Teachers, parents, tutors, and students practicing three-digit addition with regrouping.
