Place the Comma

Worksheet Description

This worksheet is centered around the educational task of inserting commas into sequences of digits to form correctly punctuated numbers. It provides a set of numbers in rows, each containing sequences of uninterrupted digits, with space beneath each sequence for students to rewrite the numbers with the appropriate comma placements. The format is straightforward and clear, with each row of numbers labeled with the instruction to “Insert commas in the appropriate places.” Additionally, the worksheet includes a  section with emoticon faces for self-assessment.

The worksheet aims to teach students the proper placement of commas in multi-digit numbers as per the standard in English-speaking countries, where commas are used to group digits into sets of three, starting from the right. It helps build the students’ understanding of numerical structure and prepares them for dealing with large numbers in mathematics, accounting, and data interpretation. By repeatedly practicing this skill, students develop a habit of recognizing and correctly formatting large numbers. The self-evaluation section at the end prompts students to reflect on their understanding and grasp of the concept.
