(10 minutes)
• Tell the students that they will be learning about different kinds of two-dimensional (2D), or flat, shapes.
• Explain that 2D shapes are flat shapes, and point to one example in the classroom.
• Read A Triangle for Adaora to the students.
• Prior to reading each page, ask your students to name any types of shapes that they recognize.
(5 minutes)
• Using either the SMART Board file of the shapes poster or a printed PDF version of the poster, model the process of identifying the shapes based on the numbers of sides that make each shape.
• Count and label the sides of each shape, including a circle, rectangle, triangle, and square.
(10 minutes)
• Display a printed copy of the shapes poster for student reference, or draw and label each of the shapes on the board.
• Distribute all four of the Counting Shapes worksheets to each of your students.
• Have your students take turns circling the matching shapes in the pictures and naming the shapes. Circulate around the room to check for understanding as students are working.
(10 minutes)
• Read the directions for Trace, Color, Write, and have students work independently on tracing the shapes, coloring them according to the key, and writing a matching letter on each shape.
• Circulate around the room, repeating directions as needed.
• Enrichment: Introduce the hexagon, which has six sides. Have your students draw hexagons.
• Support: For students who have difficulty with shape identification, reteach the shapes and have them draw the shapes in the air with their fingers, saying the name of the shape as they draw the shape. Refer students directly back to the poster that gives examples of different kinds of shapes.
• Students can use any type of publishing program such as Google Draw or Paint to create different examples of triangles, circles, squares, and rectangles.
(5 minutes)
• Have your students complete the Shape Jumble worksheet, identifying and coloring the specified shapes.
• Using that same worksheet, call out each shape and have the students point to one of the shapes that you call out.
(5 minutes)
• Sing the “Flat Shapes” song to the tune of one verse of “The Farmer in the Dell” with the students.
• Invite the students to name all of the shapes and identify which shape is missing from the song.
• Once the students name the rectangle as the missing shape, ask the students to name the shape that is most similar to a rectangle. Your students should name the square because it has four sides.
• Using one page from the book, Shapes, Shapes, Shapes by Tana Hoban, have the students name and identify the various shapes in the picture.
