Your next great Lessn starts here.

Welcome to Shapes: Counting Corners – Greet our shape explorers – Today’s adventure: flat shapes – Shapes like squares, circles, and triangles – Spot shapes in the classroom – Look for shapes in books, blocks, and windows – Counting corners of shapes – Corners are where two sides meet. Let’s count! | Begin the class with a warm welcome, engaging the children’s curiosity about the world of shapes. Introduce the concept of flat shapes, which can be found everywhere in our environment. Encourage the children to look around the classroom and identify shapes they can see, such as the pages of a book (rectangle), clock (circle), or door (rectangle). Explain that shapes have corners where the sides meet, and demonstrate counting corners on various shapes. For example, a triangle has three corners, a square has four. This activity will help children begin to understand the properties of shapes in a fun and interactive way.

Let’s Learn About Corners! – Corners: Where two sides meet – Shapes have different corners – Like squares have 4, triangles have 3 – We can count corners together – Use blocks or paper shapes to count – Corners are everywhere! | This slide introduces the concept of corners to Pre-K students. Begin by explaining that corners are points where two sides of a shape come together. Use visual aids like blocks or paper cut-outs to show different shapes and their corners. Encourage the students to touch and count the corners on various shapes. Make the learning interactive by asking them to find corners in the classroom, like on tables or windows. This hands-on activity will help them recognize and understand the concept of corners in a fun and engaging way.

Counting Corners on Squares – A square has four sides – A square has four corners – Let’s count the corners together – Use your fingers to point at each corner – Counting: 1, 2, 3, 4! – Practice counting the corners aloud | This slide introduces the concept of counting corners on squares, which is a fundamental part of understanding shapes for Pre-K students. Emphasize that a square is a special shape with four equal sides and four corners. Encourage the children to use their fingers to point at each corner of a square as they count. This tactile approach helps reinforce the concept. Make the counting fun and interactive by having the children count aloud together. You can bring in square objects or draw squares on the board for a visual aid. The goal is to make the children comfortable with identifying and counting corners on squares.

Counting Corners on Triangles – Triangles have three sides – Triangles have three corners – Let’s count: 1, 2, 3 corners! – Practice counting corners with me: one, two, three! | This slide is designed to introduce Pre-K students to the concept of counting corners on shapes, starting with triangles. Emphasize that a triangle is a shape with three straight sides and three corners. Use a visual representation of a triangle and point to each corner as you count together with the class. Encourage the students to use their fingers to point at the corners as they count. This activity helps to reinforce their counting skills and shape recognition. You can also bring in physical triangle shapes for the students to touch and count the corners. This tactile experience can further solidify their understanding of the concept.

Counting Corners on Rectangles – A rectangle has four sides – A rectangle has four corners – Counting corners together – Let’s count: 1, 2, 3, 4! – Rectangles are like squares – Both have 4 sides and 4 corners | This slide is designed to help Pre-K students recognize and count the corners of rectangles, a fundamental concept in understanding flat shapes. Start by showing them a rectangle and pointing out the four distinct sides. Then, guide them to notice each corner where two sides meet. Encourage the students to count the corners out loud together, reinforcing the number four. Highlight the similarity between rectangles and squares to help them make connections between different shapes. For an engaging activity, provide students with various cut-out shapes and ask them to identify and count the corners of each rectangle they find.

Finding Shapes Around Us – Search for squares in the room – Squares have 4 equal sides and corners, like a window – Look for triangles nearby – Triangles have 3 corners, like a slice of pizza – Find rectangles in the classroom – Rectangles have 4 corners but longer on two sides, like a door – Discuss the corners we find | This slide is designed to encourage students to observe and identify basic shapes in their immediate environment, reinforcing their understanding of flat shapes and their properties, such as corners. Encourage the children to walk around the classroom and find objects that match the shapes mentioned. For each shape, discuss how many corners they have and how they can tell the shape apart from others. This activity helps students apply their knowledge of shapes to real-world objects, enhancing their spatial awareness and descriptive abilities.

Shape Hunt Activity – Let’s go on a shape hunt! – Find objects with corners – Look for squares, rectangles, or other flat shapes around us – Draw the shapes on paper – Use crayons to draw the shapes you found – Show and tell with the class – Share your drawings with friends | This class activity is designed to help Pre-K students recognize and count corners on various shapes in a fun and interactive way. Encourage the children to explore the classroom and identify as many flat shapes as they can, such as the corners of a book, a door, or a window. Provide them with paper and crayons for drawing. Once they have completed their shape hunt, organize a show and tell session where each student can present their findings and practice their counting skills. This activity not only reinforces the concept of corners but also promotes public speaking and sharing in a group setting. Possible variations of the activity could include grouping shapes by the number of corners, using different colors for different shapes, or even creating a collage of the shapes found.

Counting Corners: Great Job! – Celebrating our learning – Counting corners on shapes – We counted corners on squares, triangles, and more. – Shapes are all around us – Look for shapes at home, in the park, everywhere! – Practice finding corners – Keep counting corners on any shape you find. | This slide wraps up the lesson on counting corners of flat shapes. Congratulate the students on their hard work and remind them of what they’ve learned about identifying and counting corners on various shapes. Emphasize that shapes are a part of our everyday environment and encourage them to continue observing and finding corners in the world around them. Reinforce the concept by suggesting they practice with their parents or guardians at home, turning it into a fun game of shape exploration.
