Are you looking for a powerful tool to help your students develop number sense and critical thinking skills? Look no further than the 120 chart! This simple yet versatile tool can be used in a variety of ways to support math learning, from counting and skip counting to place value, addition, subtraction, multiplication, and more. In this article, we’ll explore why the 120 chart is so valuable and provide practical tips and strategies for using it effectively with your students.

## What is a 120 Chart and Why is it Important?

A 120 chart is a grid that lists the numbers from 1 to 120 in order. It can be used to help students develop a strong understanding of number relationships, patterns, and operations. Here are some reasons why the 120 chart is so important:

• It helps students visualize and understand number patterns, such as counting by 2s, 5s, or 10s.
• It supports place value understanding by showing the relationship between ones, tens, and hundreds.
• It helps students develop mental math skills by providing a visual tool for addition, subtraction, multiplication, and division.
• It can be used in a variety of games and activities to make math learning fun and engaging.

## How to Teach and Use the 120 Chart Effectively

Now that you know the benefits of using a 120 chart, let’s explore some practical tips and strategies for teaching and using it effectively with your students.

Before diving into using the 120 chart for more complex math concepts, start by introducing the chart gradually. Begin with simple counting activities, such as counting by 1s, 2s, 5s, or 10s. As students become more comfortable with the chart, you can gradually introduce more complex activities, such as skip counting or finding patterns.

### Use the Chart for Place Value Understanding

The 120 chart is a powerful tool for developing place value understanding. Encourage students to identify patterns in the chart, such as groups of ten or vertical columns, which can help them see the relationship between ones, tens, and hundreds. You can also use the chart to help students visualize and compare numbers, such as by asking them to find the number that is one more, one less, ten more, or ten less than a given number.

### Play Games and Activities with the Chart

One of the best ways to make math learning fun and engaging is by incorporating games and activities that use the 120 chart. Here are some ideas to get you started:

• Race to 100: Students take turns rolling a dice and moving that many spaces on the chart. The first student to reach 100 wins!
• Fill in the Blanks: Write a series of numbers on the chart, but leave some blank spaces. Have students fill in the missing numbers based on the pattern.
• Number Puzzles: Cut the 120 chart into pieces and have students put it back together like a puzzle.
• Mystery Number: Choose a number on the chart and give students clues about it (such as “It is greater than 50” or “It is an even number”). Students must use the chart to guess the mystery number.

### Use the Chart for Mental Math

The 120 chart is also a great tool for developing mental math skills. Encourage students to use the chart to help them add, subtract, multiply, and divide. For example, to add 27 and 15, students can start at 27 on the chart and count up 15 spaces to find the answer (which is 42). Similarly, to multiply 6 and 8, students can find 6 on the chart and count over 8 spaces to find the answer (which is 48).

### Encourage Independent Exploration

Finally, don’t be afraid to let students explore the 120 chart on their own. Encourage them to find patterns, make connections, and create their own games and activities. By giving students the freedom to explore and discover, you can help them develop a deeper understanding and love of math. In conclusion, the 120 chart is a powerful tool for developing number sense and critical thinking skills in students. By introducing the chart gradually, using it for place value understanding, playing games and activities, using it for mental math, and encouraging independent exploration, you can help your students become confident and proficient math learners. So go ahead and give the 120 chart a try – your students (and your own math teaching skills) will thank you!
