Worksheet Description

The worksheet provides a list of numbers in a central column, each within its own row. Students are instructed to write the number that is one less than the given number in the column labeled “One less” on the left side, and the number that is one more in the column labeled “One more” on the right side. The numbers provided range from the lower thirties to the lower sixties. This layout allows for an organized approach where students can systematically work through the sequence of numbers.

This worksheet is designed to teach students the concept of immediate predecessor and successor numbers. It focuses on reinforcing their ability to quickly determine which numbers come directly before and after a given number. This skill is fundamental to understanding numerical order and is a precursor to more advanced arithmetic operations. The exercise enhances mental arithmetic skills, encourages numerical fluency, and helps students practice basic addition and subtraction in a focused setting.
