Math 3rd Grade Subtraction Worksheet Diagrams and Charts

When teaching third graders subtraction, it can be helpful to use diagrams and charts to help them visualize the concepts. These visual aids can make it easier for students to understand how to solve subtraction problems. There are a variety of different diagrams and charts that can be used to teach subtraction, and the best one to use will depend on the individual student’s learning style.

One common type of diagram used to teach subtraction is a number line. A number line is a horizontal line with numbers marked at regular intervals. To solve a subtraction problem using a number line, students start at the larger number and then move to the left along the number line, counting by ones until they reach the smaller number. The number they land on is the difference between the two numbers.

Another common type of diagram used to teach subtraction is a part-part-whole diagram. A part-part-whole diagram is a rectangle that is divided into two parts. The larger part represents the whole, and the smaller part represents one of the parts. To solve a subtraction problem using a part-part-whole diagram, students first identify the whole and the part. Then, they find the difference between the whole and the part. The difference is the other part.

Charts can also be helpful for teaching subtraction. One common type of chart used to teach subtraction is a subtraction table. A subtraction table is a grid with two columns and several rows. The first column contains the minuend (the larger number), the second column contains the subtrahend (the smaller number), and the last column contains the difference. To solve a subtraction problem using a subtraction table, students simply find the row that contains the minuend and the subtrahend, and then read the difference from the last column.

Using diagrams and charts to teach subtraction can be a helpful way to make the concepts more concrete for students. These visual aids can help students to visualize the problems and to understand the steps involved in solving them.

Part-part-whole diagrams

Part-part-whole diagrams are a powerful tool for teaching third graders how to subtract. They can help students to visualize the subtraction process, and to understand the relationship between the whole, the parts, and the difference.

• Component 1: Representing the Whole
  Part-part-whole diagrams start by representing the whole as a rectangle or square. This helps students to visualize the whole amount that they are subtracting from.
• Component 2: Dividing the Whole into Parts
  Once the whole has been represented, it is divided into two parts. One part represents the minuend, and the other part represents the subtrahend. This helps students to see how the whole is made up of two smaller parts.
• Component 3: Finding the Difference
  The difference between the minuend and the subtrahend is the amount that is being subtracted. This is represented by the empty space in the diagram. Students can count the number of empty squares to find the difference.
• Component 4: Relating the Parts to the Whole
  Part-part-whole diagrams help students to see how the parts relate to the whole. They can see that the whole is equal to the sum of the parts, and that the difference is the amount that is left over when one part is taken away from the whole.

Part-part-whole diagrams are a valuable tool for teaching subtraction because they are simple to use and understand. They can help students to visualize the subtraction process, and to develop a strong understanding of the relationship between the whole, the parts, and the difference.

Subtraction tables
