Vocabulary
Input: The number that is given in the table and needs to be divided by the rule.
Output: The result after applying the division rule to the input.
Rule: The operation that needs to be applied to the input number to get the output (e.g., divide by 2).

Materials and Preparation
- Whiteboard and markers
- TeachTastic Worksheet Pack for Division Input and Output Tables
- Division tables or charts
- Input-output table templates for individual practice
Learning Objectives
- Students will identify and apply a division rule to complete input and output tables.
- Students will divide numbers accurately based on a given rule.
- Students will recognize and explain patterns in input and output tables.
Introduction
Begin the lesson by introducing the concept of input and output tables. Explain that these tables show how numbers change when a specific rule is applied, in this case, division. Use a simple example on the board, such as dividing by 2, and show how the input number changes to the output number. Ask students if they have seen similar tables before and what patterns they notice.
Explicit Instruction/Teacher modeling
Present an input-output table with a simple rule, such as "Divide by 2." Start with the input numbers 4, 6, 8, and 10, and show how each number is divided by 2 to produce the output. Write out each division step clearly on the board: 4÷2=2, 6÷2=3, etc. Fill in the table together with the class, emphasizing how the rule is applied consistently to each input number to generate the output.
Guided Practice
Hand out the TeachTastic Worksheet Pack for Division Input and Output Tables. Work through the first table as a class, identifying the rule and applying it to each input number. Ask students to solve the division problems and write the results in the output column. Encourage them to discuss any patterns they see, such as the output numbers decreasing by a consistent amount.
Independent Practice
Allow students to complete additional tables in the TeachTastic Worksheet Pack independently. They should identify the rule, divide the input numbers by the rule, and fill in the corresponding output numbers. Circulate the room to offer guidance and ensure that students are correctly applying the division rule.
Differentiation
Support
- Provide additional practice with division tables or charts for students who need reinforcement of basic division facts.
- Offer visual aids, such as a number line, to help students understand the division process.
- Pair struggling students with a peer tutor who can guide them through the steps of completing the tables.
Extension
- Challenge students to create their own input-output tables with more complex division rules (e.g., "Divide by 3 and subtract 1").
- Introduce input-output tables that involve multiplication or a combination of operations for advanced students.
- Explore how input-output tables can be used in real-life scenarios, such as calculating discounts or sharing resources.
Assessment
Use the completed worksheets from the TeachTastic Worksheet Pack to assess students’ understanding. Check for accuracy in applying the division rule and filling in the output columns. Review their exit tickets to ensure they understand how to use input-output tables.
Review and closing
Summarize the key points of the lesson by revisiting how input-output tables work and the importance of following the rule consistently. Discuss how these tables can help us understand patterns in numbers. Allow students to ask any final questions and clarify any areas of confusion.
Misconceptions
- Misconception: Students may think that the output numbers should always decrease, regardless of the rule. Correction: Emphasize that the output depends entirely on the rule being applied, not just on the input number decreasing.
- Misconception: Students might confuse the input and output columns, leading to incorrect results. Correction: Reinforce the direction of the process—input to output—by consistently reviewing the steps in class.
- Misconception: Students might assume they can apply any operation, not just the given rule. Correction: Stress the importance of following the specific rule provided for each table to ensure correct results.
