Key Concepts

  • Equal parts are exactly the same size.
  • Shapes can be divided into different numbers of equal parts (halves, fourths, etc.).
  • The orientation of the dividing lines doesn't change whether the parts are equal.

Learning Objectives

  • Students will be able to define what equal parts are.
  • Students will be able to identify shapes divided into equal parts.
  • Students will be able to differentiate between shapes divided into equal parts and unequal parts.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what it means to share something fairly. Connect this to the idea of equal parts. Introduce the video and explain that they will be learning about identifying equal parts in shapes.
  • Video Viewing (7 mins)
    Play the 'Equal Parts | Math Lessons for 2nd Grade | Kids Academy' video. Encourage students to pay close attention to the examples of shapes cut into equal and unequal parts.
  • Discussion (5 mins)
    After the video, have a class discussion about what they learned. Use the discussion questions below to guide the conversation.
  • Interactive Exercise: Equal Parts Sort (10 mins)
    Provide students with pre-cut shapes (squares, circles, rectangles) that are divided into various parts, some equal and some unequal. Have them sort the shapes into two categories: 'Equal Parts' and 'Not Equal Parts'.
  • Worksheet Activity (10 mins)
    Distribute a worksheet with various shapes divided into different numbers of parts. Students will color in the shapes that are divided into equal parts. This can be adapted to include brownies similar to the video's activity.
  • Wrap-up (3 mins)
    Review the definition of equal parts. Reiterate that equal parts must be exactly the same size and shape. Give a real-world example such as splitting a sandwich in half. Briefly introduce the quiz to test their understanding.

Interactive Exercises

  • Equal Parts Sort
    Students sort pre-cut shapes (squares, circles, rectangles) divided into various parts (some equal, some unequal) into 'Equal Parts' and 'Not Equal Parts' categories.
  • Brownie Maze
    Draw your own brownie maze! Students create a maze with brownies and decide which brownies are cut into equal parts to find the chocolate party.

Discussion Questions

  • What does it mean for something to be in equal parts?
  • How can you tell if a shape is divided into equal parts?
  • Can a shape be divided into more than two equal parts?
  • Give an example of something you might share into equal parts.

Skills Developed

  • Visual discrimination
  • Critical thinking
  • Problem-solving
