1 to 20 Worksheets

About These 15 Worksheets

The main goal of these worksheets is help students begin to master the sequence of numbers between 1 and 20. This is a foundational skill that start students off in the right direction towards their understanding of math.

You know how you learn different things in math like counting, adding, subtracting, comparing numbers, or even understanding how numbers are arranged on a number line? These worksheets are designed to help you practice all those skills and more. For example, one worksheet will have you practice counting from 1 to 20. Another worksheet might ask you to add or subtract numbers within the range of 1 to 20. Yet another might ask you to arrange numbers from 1 to 20 in increasing or decreasing order.

The thing with learning is that the more you practice, the better you get. If you’re trying to learn how to use a screwdriver, the more screws you tighten or loosen, the more comfortable and proficient you’ll become at using the screwdriver. Similarly, the more you use 1 to 20 Worksheets to practice math, the better you’ll get at understanding and using numbers between 1 and 20.

These worksheets are also kind of like a game of soccer or basketball. When you’re playing these games, you have to practice different skills, like dribbling, passing, shooting, and so on. You can’t just jump straight into playing a match without knowing or practicing these skills. Likewise, before you jump into more complicated math topics, you need to have a good grip on the basics. And the numbers 1 to 20 are a fundamental part of those basics. Practicing with these worksheets is like practicing your dribbling or shooting before a game, but for math.
