Missing 2nd Addend

Worksheet Description

This worksheet presents a set of subtraction problems, where students are given a minuend (the first number) and a difference (the result), and they must find the subtrahend (the number to be subtracted). The format is simple and straightforward, with twenty questions laid out in a vertical list, each with a blank space where the subtrahend should be written. The problems use single-digit numbers and are designed in such a way that they can be solved mentally, making the worksheet suitable for students who are just beginning to learn subtraction or need practice with mental arithmetic.

The worksheet is focused on teaching students the concept of ‘finding the missing number’ in a subtraction equation. It helps students understand that subtraction is not just about taking away but can also be about determining what number was taken away to arrive at a given result. This skill is fundamental in building a deeper understanding of how numbers relate to each other in subtraction. By working through these problems, students develop their problem-solving abilities and improve their mental math skills, both of which are critical in their overall mathematical education.
