Lesson Plan: Translations in Mathematics

Subject: Mathematics

Year/Grade: 7

Duration: 30 Minutes

Topic: Translations

---

Learning Objectives

By the end of this lesson, students will be able to:

• Define what a translation is in the context of geometry.
• Identify and perform translations of shapes on a coordinate grid.
• Describe the characteristics of shapes before and after a translation.

---

Introduction (5 minutes)

• Engage the students by asking them if they've ever seen a shape move across a screen or paper. Discuss examples of translations, such as video game characters moving or images sliding.
• Introduce the term "translation" as a specific type of transformation in mathematics where a shape is moved from one position to another without changing its size, shape, or orientation.

Direct Instruction (10 minutes)

Definition of Translation

• A translation moves every point of a shape the same distance in a given direction.

  Example:

  • If a point (x, y) is translated by (2, 3), the new position will be (x + 2, y + 3).

Key Characteristics of Translations

• The shape and size remain unchanged.
• The orientation of the shape does not change.
• A translation can be described using vectors.

How to Perform a Translation

1. Identify the starting coordinates of the shape.
2. Determine the translation vector (horizontal and vertical movement).
3. Apply the vector to each vertex of the shape.

---

Guided Practice (10 minutes)

• Activity: Distribute coordinate grids to each student along with a set of shapes (triangles, squares) marked with their vertices.

  1. In pairs, students will select a shape and a translation vector (e.g., (3, -2)).
  2. Students will calculate the new coordinates for each vertex of the shape after applying the translation vector.
  3. They will then draw the translated shape on the grid provided and label the new coordinates.

Teacher Support

• Circulate the room to assist students as they work, ensuring they understand how to apply the translation vector correctly.

---

Independent Practice (5 minutes)

• Hand out a worksheet with various shapes and translation vectors.

  Tasks:

  1. Translate each shape using the given vector.
  2. Write down the new coordinates of each vertex.
  3. Draw the translated shapes on the provided space.

---

Conclusion (5 minutes)

• Review the key concepts covered in the lesson:
  • What a translation is.
  • How to identify and perform translations.
• Check for Understanding: Ask students to share one important thing they learned during the lesson.
• Preview the Next Lesson: Mention that in the next lesson, they will explore other transformations, such as reflections and rotations.

---

Resources Needed

• Coordinate grids
• Shapes (triangles, squares) with labelled vertices
• Whiteboard and markers
• Worksheets for independent practice

---

Assessment

• Formative: Observations during guided practice and student responses during the conclusion discussion.
• Summative: Worksheets collected at the end of the lesson for evaluation.
