Welcome to Shapes: Becoming Shape Creators! – Learn to make new shapes – Explore composing 2D shapes – Combining shapes like puzzle pieces – Become a shape creator – Have fun with shapes – Use squares, triangles, and circles to create | This slide introduces the concept of composing two-dimensional shapes, which is a fundamental skill in understanding geometry. The goal is to show students that by combining simple shapes like squares, triangles, and circles, they can create new shapes. It’s like putting together pieces of a puzzle. During the class, provide students with cut-outs of basic shapes and encourage them to arrange them into new shapes. This hands-on activity will help them understand how shapes can be composed to form others. By the end of the lesson, students should be able to recognize and create composite shapes, understanding that these are made up of simpler, familiar shapes. Make the learning process enjoyable by praising their creativity and unique compositions.

Exploring Two-Dimensional Shapes – What are 2D shapes? – Shapes that are flat with length and width – Examples: Square, Rectangle – A square has 4 equal sides, rectangles have 2 long and 2 short sides – Examples: Triangle, Circle – Triangles have 3 sides, circles are round – Let’s find 2D shapes! | This slide introduces first graders to the concept of two-dimensional shapes. Begin by explaining that 2D shapes are flat and only have length and width, unlike 3D shapes which also have height. Show them examples of each shape and highlight their properties, such as a square having four equal sides and a rectangle having two pairs of equal sides. Use physical cut-outs of shapes to help them identify and differentiate between them. Encourage the students to look around the classroom and find objects that match these shapes to reinforce their understanding. The activity will be interactive, allowing students to engage with the shapes directly.

Creating New Shapes by Composing – Combine shapes to create new ones – ‘Composing’ shapes is like a puzzle – Think of putting puzzle pieces together to make a picture – Explore how shapes fit together – Try putting squares and triangles together: What do you get? – Composing shapes is fun and creative | This slide introduces the concept of composing two-dimensional shapes, which is a fundamental part of understanding geometry for first graders. Encourage the students to think creatively about how different shapes can fit together to form new ones, much like assembling a puzzle. Provide examples of simple shapes combining to form more complex shapes, such as squares and triangles forming a house. During the activity, students can use cut-out shapes to experiment with composing their own new shapes. This hands-on experience will help solidify their understanding of how shapes can be combined and will serve as a foundation for more complex geometric concepts.

Let’s Compose a Rectangle! – Two squares side by side – Squares make a rectangle! When we place them together, their sides touch and form a rectangle. – Find shapes at home Look for objects like books or tiles that are square-shaped. – Create your own rectangle Use your squares to form a rectangle and show us! | This slide is designed to help first graders understand how rectangles can be composed from two squares. Start by showing them two squares side by side and how they form a rectangle when their edges are touching. Encourage the students to explore their environment at home to find square objects that can be put together to form a rectangle. This activity will help them recognize shapes in everyday objects and understand how two-dimensional shapes can combine to form new shapes. Provide guidance on how to safely find and use objects to create rectangles and encourage them to share their findings in the next class.

Composing Shapes with Circles – Combining circles together – Create a caterpillar with circles – Place circles in a row to form a caterpillar’s body – Build a train using circles – Circles can be train wheels or carriages – Let’s compose new shapes | This slide is aimed at helping first graders understand that shapes can be combined to create new objects. Start by asking the students what they think will happen if we put circles together. Guide them to see that by arranging circles in different patterns, they can make familiar objects like caterpillars or trains. Encourage them to think creatively and explore composing their own shapes using circles. Provide them with cut-out circles and let them experiment with composing shapes on paper. This activity will help them understand the concept of composition in geometry and recognize shapes in everyday objects.

Activity Time: Shape Creators! – Become a shape creator – Use cut-outs to make new shapes – Combine triangles, squares, etc., to form a new shape – Share your shape with the class – Explain your shape to your friends – Have fun with shapes! | This activity is designed to encourage creativity and understanding of how two-dimensional shapes can combine to form new shapes. Provide students with various cut-outs of basic shapes like triangles, squares, rectangles, and circles. Encourage them to experiment by combining these shapes to create a new, unique shape. Once they have created their shape, ask them to share it with the class and describe what shapes they used and how they arranged them. This will help reinforce their understanding of shapes and how they can interact. Possible activities include creating animals, objects, or even a picture using the shapes. Ensure that each student has a chance to share and that the classroom environment is supportive and encouraging.

Class Activity: Shape Art! – Create a picture with shapes – Make a house, robot, or your choice – Use composed two-dimensional shapes – Combine squares, triangles, circles, etc. – We’ll display our art in class | This activity is designed to help first graders understand and apply their knowledge of composing two-dimensional shapes. Provide students with various cut-out shapes like squares, triangles, and circles. Encourage them to think creatively and compose these shapes to form a picture of a house, robot, or anything they can imagine. Offer guidance on how shapes can be combined or overlapped to create new forms. Once completed, plan to display their artwork around the classroom to celebrate their creativity and understanding of geometric shapes. This will also enhance their spatial reasoning skills and their ability to recognize and utilize shapes in different contexts.

Review and Goodbye, Shape Creators! – Celebrating our shape creation – Today’s lesson on composing shapes – We combined shapes to make new ones – Encouragement to keep exploring – Look for shapes around you and create – Compose shapes in daily life | This slide is meant to wrap up the lesson on composing two-dimensional shapes. It’s a moment to celebrate the students’ efforts in learning how to combine simple shapes to create new ones. Reinforce the idea that shapes are not just in the classroom; they are everywhere in the world around us. Encourage the students to keep an eye out for shapes in their environment and think about how they might combine them to make new shapes. This will help solidify their understanding and keep them engaged with the concept outside of the classroom. Remember to praise their creativity and effort to foster a positive attitude towards learning math.
