Your next great Lessn starts here.

Welcome to Shapes: Triangles! – Greet the class with a smile – Today’s shape: the triangle – A triangle has 3 sides and 3 corners – Ask kids about known shapes – Introduce triangles with enthusiasm – Show examples of triangles in the classroom | Begin the class with a warm and cheerful greeting to set a positive tone. Introduce the triangle by emphasizing its uniqueness among shapes. Engage the children by asking them to share shapes they are already familiar with, fostering a participatory environment. When introducing triangles, ensure to highlight the key characteristics such as having three sides and three corners. Use tangible examples from the classroom like triangular blocks or cutouts to help them identify triangles in their surroundings. This interactive approach will help kindergarteners recognize and remember the shape effectively.

What is a Triangle? – A triangle has three sides – It has three corners or ‘vertices’ – Let’s count the sides and vertices! – We’ll look at a picture and count 1, 2, 3 sides and vertices together. | This slide introduces the basic concept of a triangle to Kindergarten students. Start by explaining that a triangle is a shape with three straight sides. Then, teach them the term ‘vertices’ as the name for the corners of a triangle. Use a picture of a triangle to visually demonstrate the count of sides and vertices. Encourage the students to count aloud with you. This interactive approach helps to reinforce their understanding of the number three and the properties of a triangle. Make sure to use a clear and simple image of a triangle for this activity.

Triangle Types – Triangles are different shapes – Equilateral: all sides equal – Like three equal sticks stuck together – Isosceles: two sides the same – Two long sticks, one short stick – Scalene: all sides different – Three sticks, all different lengths | This slide introduces the concept of different types of triangles to Kindergarten students. Begin by explaining that triangles are shapes with three sides. Use simple language and real-world examples, such as sticks or crayons, to help them visualize. For equilateral triangles, you might say it’s like having three snacks of the same size. For isosceles, it’s like having two snacks the same size and one different. And for scalene, all snacks are different sizes. Encourage the students to draw each type of triangle and discuss the lengths of the sides. This will help them understand and remember the differences between equilateral, isosceles, and scalene triangles.

Triangles Around Us – Triangles are all around – Spot triangles in our room – Can you find any triangles near us? Maybe in shapes of objects? – Look at pictures together – We’ll view images with different triangles hidden in them. – Find the triangles we see – When we spot a triangle, let’s point it out! | This slide is designed to engage Kindergarten students in identifying triangles in their immediate environment. Begin by explaining that triangles are shapes with three sides. Encourage the children to look around the classroom and identify objects that have a triangular shape. Show them pictures with various triangles and ask them to point out the triangles they see. This activity helps students recognize triangles and understand that they can be found in many places. It’s a fun way to introduce the concept of shapes and specifically triangles in a way that is interactive and relatable to their everyday lives.

Drawing Triangles – Start with one straight line – Add two more lines from ends – Connect ends to form corners – Corners are where two lines meet – All sides should meet neatly – Check where lines start and end | This slide is aimed at teaching Kindergarten students the basic steps to draw a triangle. Begin by demonstrating how to draw a straight line on the board. Then, show them how to add two more lines starting from the ends of the first line. Emphasize the importance of the lines meeting at the corners, which are the points where two lines come together. Finally, ensure that all sides are connected without any gaps. Encourage the students to practice drawing triangles with different side lengths, and remind them that all three corners need to be closed for the shape to be a triangle. Provide hands-on activities such as drawing triangles in the air with fingers, using sticks, or tracing the edges of triangular objects.

Triangle Song Time! – Sing the triangle song – A catchy song to remember triangle properties – Learn what makes a triangle – A shape with three straight sides and three corners – Use hands to show sides and corners – Each hand can represent a corner or a side – Have fun remembering triangle features | This slide is designed to engage Kindergarten students in a fun and interactive song that teaches them about the properties of triangles. The song should have simple lyrics that explain a triangle has three straight sides and three corners. As the song plays, demonstrate with your hands how to represent the sides and corners of a triangle, and encourage the children to follow along. This kinesthetic activity helps reinforce the concept through movement and music. The goal is to make the learning experience memorable so that students can easily recall what a triangle is. After the song, you can ask the students to draw triangles in the air with their fingers to further solidify their understanding.

Class Activity: Triangle Hunt – Let’s go on a triangle hunt – Look around our classroom – Find and draw triangles – Can you find the triangle shapes? – Use your activity sheet – Draw the triangles you find on your sheet | This activity is designed to help students recognize triangles in their environment. Encourage the children to look for objects that have a triangular shape, such as a slice of pizza, a yield traffic sign, or the musical instrument triangle. Provide each student with an activity sheet that has space for drawing or pasting pictures of the triangles they find. Walk around the classroom to assist and ensure they understand the concept of a triangle. Possible activities for different students could include drawing triangles, creating triangles with craft sticks, finding triangles in classroom posters, or identifying triangles in a book. This hands-on activity will reinforce their understanding of triangles and two-dimensional shapes.

Triangle Hunt Recap – Celebrating our triangle hunt – Sharing our triangle finds – Did you find a triangle in the classroom or at home? – Triangles: three sides and corners – Each triangle has 1-2-3 sides and 1-2-3 corners! – Remembering triangle properties | This slide concludes the triangle hunt activity. Congratulate the students on their efforts during the triangle hunt and encourage them to share the triangles they found. Reinforce the concept that all triangles have three sides and three corners, which is a defining property of the shape. Use this opportunity to assess understanding by asking students to describe where they found their triangles and how they recognized them as triangles. This will help ensure that they can identify triangles in various contexts and solidify their understanding of the shape’s properties.
