  • Hello, math tutors! Elevate early education with our comprehensive lesson plan on 'how to find triangles in a shape world. This engaging guide builds on spatial awareness through interactive, hands-on activities, worksheets, and a video from

    Shapes are everywhere in our world. We can see them in buildings, objects, nature, and even our bodies. Some shapes have straight sides, and some have curved sides. Some shapes have three sides, and some have more. In this lesson, we will focus on one shape with three sides: the triangle.

What is the importance of following the triangle shape recognition lesson plan for kids?

  • Triangle shape recognition is an important lesson plan for kids because it helps them develop their spatial awareness, geometry skills, and creativity. Triangles are one of the basic shapes that can be used to create many other shapes and patterns.

    By learning to recognize and name triangles, kids can also improve their vocabulary, communication, and problem-solving abilities. Triangles are everywhere in our world, from buildings to art to nature. Teaching kids to identify and appreciate triangles can foster their curiosity and interest in math and science.

  • Grade Level: Pre-K | Kindergarten | Grade 1

    Duration: 20 - 30 minutes

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

    • Recognize triangles, among other shapes
    • Name the characteristics of a triangle
    • Draw their triangles

This lesson plan is flexible and adaptable to different classroom settings and situations. You can adjust the duration, difficulty, and number of activities according to your students' needs and interests. You can also use different materials and resources that are available to you.

  • Previous knowledge

    Students should be familiar with basic shapes such as circles, squares, and rectangles.


    For this lesson, you will need:

    • A computer or a projector to show the video
    • Paper and crayons for each student
    • A set of shape cards for each group (the cards should have different shapes such as circles, squares, rectangles, triangles, pentagons, hexagons, etc.)
    • A poster or a chart paper with the word "triangle" and a picture of a triangle



    • Warm-up

      • Show the video from ( to the students.
      • The video will introduce the concept of triangles and show some examples of triangles in real life.
      • Ask the students to pay attention to the video and try remembering what a triangle looks like.
    • Introducing the concept

      After the video, ask the students to recall what they learned from the video. Ask them questions such as:

      • What is a triangle?
      • How many sides does a triangle have?
      • How many corners does a triangle have?
      • Can you name some things that are shaped like triangles?


      • Write their answers on the board or a chart paper.
      • Review their answers and correct any misconceptions.
      • Explain that a triangle is a shape that has three straight sides and three corners.
      • Show them the poster or the chart paper with the word "triangle" and a picture of a triangle.
      • Please point out the sides and the corners of the triangle and ask them to repeat after you.
    • Activities and games

      • Divide the students into small groups of 3 or 4.
      • Give each group a set of shape cards.
      • Ask them to sort the cards into two piles: one for triangles and one for non-triangles.
      • Tell them to work together and help each other.
      • Walk around the room and monitor their progress.
      • Provide feedback and guidance as needed.
    • Group Sharing

      After the activity,

      • Ask each group to share their results with the class.
      • Ask them to show their piles of cards and explain how they sorted them.
      • Praise their efforts and reinforce their understanding of triangles.
      • Ask them questions such as:
      • How did you know which cards were triangles?
      • How did you know which cards were not triangles?
      • Did you find any cards that were tricky or confusing?
      • What did you learn from this activity?
    • Conclusion

      Wrap up the lesson by reviewing the main points. Ask the students to summarize what they learned today. Remind them that:

      • A triangle is a shape that has three straight sides and three corners
      • Triangles can be found in many things around us
      • We can sort shapes into triangles and non-triangles by looking at their sides and corners


✨ Assessment

Give each student a paper and a crayon. Ask them to draw their own triangle on the paper. Collect their papers and check their work. Provide feedback and praise as appropriate.
