Exploring Cubes and Rectangular Prisms – What are 3D shapes? – Shapes that have length, width, and height. – Can you name 3D shapes? – Discovering cubes – A cube has 6 equal square faces. – Learning about rectangular prisms – Rectangular prisms have 6 faces too, but not all are equal. | Begin the lesson by introducing the concept of three-dimensional shapes, emphasizing that unlike flat shapes, 3D shapes have depth. Ask the students to name any 3D shapes they’re already familiar with to engage them and assess prior knowledge. Then, focus the discussion on cubes and rectangular prisms, highlighting the characteristics of each shape. For cubes, point out that all the faces are squares and the same size. For rectangular prisms, explain that the faces are rectangles and can be different sizes. Use physical examples if possible, and encourage students to touch and count the faces, edges, and vertices to better understand these shapes.

Exploring Cubes – A cube has 6 square faces – Like dice or blocks, all sides are equal squares – Each corner meets 3 edges – Look at a box’s corners where lines meet – Counting cube’s faces, edges, and corners – We’ll use a cube to count them in class together! | This slide introduces the concept of a cube to first graders. Emphasize that a cube is a special box where all the sides are the same and shaped like squares. Show them a physical cube, like a dice or a block, to help them visualize. Explain that the corners of the cube are where three edges meet, and you can feel them with your fingers. During the class, have a hands-on activity where students can count the faces, edges, and corners of a cube together. This will help them understand the three-dimensional nature of cubes and how they are different from flat shapes.

Exploring Rectangular Prisms – A stretched cube is a prism – It has 6 faces, some rectangles – Not all faces are squares like a cube – Counting faces, edges, corners – We’ll use blocks to count them together – Understanding a 3D shape – Recognizing prisms in everyday objects | This slide introduces first graders to the concept of a rectangular prism as part of their study of three-dimensional shapes. Begin by explaining that a rectangular prism is similar to a cube but stretched out, which changes the shape of some of its faces from squares to rectangles. Use physical blocks or manipulatives to help students count the faces, edges, and corners, reinforcing their understanding of the shape’s properties. Encourage them to touch and count each part. Conclude by helping students recognize rectangular prisms in everyday objects around them, such as boxes, books, and bricks, to connect the concept to the real world.

Comparing Cubes and Rectangular Prisms – Similarities of cubes and prisms – Both have flat faces, edges, and vertices – Differences between the two – Cubes have equal sides, prisms have different length sides – Building blocks activity – Let’s build a cube and a prism with blocks! | This slide aims to help first graders understand the concept of three-dimensional shapes by comparing cubes and rectangular prisms. Start by discussing the similarities, such as both having flat faces, straight edges, and corners (vertices). Then, explain the differences, emphasizing that a cube has all sides of equal length, while a rectangular prism has sides of different lengths. For the class activity, provide students with building blocks and guide them to construct their own cube and rectangular prism. This hands-on activity will reinforce their understanding of the shapes’ properties. Be prepared with additional activities for early finishers, such as drawing the shapes or sorting objects based on their shapes.

Finding 3D Shapes Around Us – Cubes in our classroom? – Look around! Are there dice, boxes, or blocks shaped like cubes? – Rectangular prisms at home? – Maybe books, cereal boxes, or bricks are rectangular prisms? – Draw or list your 3D finds – Share with the class! – We’ll discuss as a group what you’ve discovered! | This slide is meant to encourage students to observe and interact with their environment to identify cubes and rectangular prisms. Prompt them to think about everyday objects they encounter, like toy blocks or their lunchboxes, as examples of cubes, and books or shoeboxes as rectangular prisms. The activity of drawing or listing these items will help solidify their understanding of these shapes. In the next class, create a show-and-tell session where students can share their findings and learn from each other’s observations. This will help them recognize these 3D shapes not just in theory but in practical, tangible ways.

Class Activity: Shape Hunt Adventure – Let’s search for shapes in our room! – Spot real cubes and prisms around us – Look for cube-shaped and prism-shaped objects – Team up for a shape hunt worksheet – Use the worksheet to record your discoveries – Share your findings with the class | This activity is designed to help students recognize cubes and rectangular prisms in their environment, reinforcing the concept of three-dimensional shapes. Before starting, explain what cubes and rectangular prisms look like. Cubes have 6 equal square faces, while rectangular prisms have faces that are rectangles. Divide the class into pairs to foster teamwork and provide each pair with a worksheet to document their findings. The worksheet should have spaces to draw or write down the objects they find. Encourage students to look at bookshelves, blocks, and other classroom items. After the hunt, ask pairs to present one object they found and explain why it’s a cube or prism. This will help them articulate their understanding and practice using geometric vocabulary.

Review and Share: Shape Hunt – Review our shape hunt finds – Share your favorite cube or prism – Did you find a cube or a prism that was really interesting? – Discuss why shapes are used – Are cubes used for storage? Why prisms for boxes? – Think about shapes in daily life | This slide is meant to recap the shape hunt activity. Encourage the students to think about the shapes they found and select the most interesting cube or rectangular prism to share with the class. Facilitate a discussion on why certain shapes are used for particular objects, such as the stability of a cube for storage or the space efficiency of a rectangular prism for packaging. This will help students connect the geometric concepts to real-world applications. Prepare to guide the conversation with examples and prompt students to consider how these shapes fit into their everyday lives.

Let’s Build: Cubes and Rectangular Prisms – Build cubes and prisms with playdough – Count faces, edges, and corners A cube has 6 faces, 12 edges, and 8 corners; a prism has 6 faces, 12 edges, and 8 corners too. – Show and tell with your shapes – Understand 3D shapes better This helps us see how 3D shapes look and feel in real life. | This activity is designed to help first graders understand the properties of cubes and rectangular prisms by creating them with their own hands. Provide each student with playdough and toothpicks. Guide them to form the shapes and count the number of faces (flat surfaces), edges (where two faces meet), and corners (points where edges meet). Encourage them to present their shapes to the class, fostering a sense of accomplishment and allowing them to observe the variety of shapes created by their peers. This tactile experience reinforces their understanding of three-dimensional shapes in a fun and interactive way. Possible variations of the activity could include using different materials, working in pairs, or challenging students to create other 3D shapes.

Exploring 3D Shapes: Cubes and Rectangular Prisms – Congrats on learning about 3D shapes – 3D shapes are everywhere around us – Find 3D shapes in your home – Look for cubes and prisms around the house – Share your 3D shape discoveries – Bring your findings to class for show and tell | This slide is meant to wrap up the lesson on cubes and rectangular prisms by congratulating the students on their hard work. It’s important to encourage them to observe their surroundings and identify 3D shapes in their everyday environment. This will help reinforce their understanding of the concepts learned in class. For the next class, ask the students to bring examples of cubes and rectangular prisms they found at home. This could be in the form of toys, boxes, or any household items. This activity will make the learning experience more interactive and tangible.
