Using Children’s Literature to Reinforce Geometry

posted by Dr. Jeanne White

As young children are formally introduced to the names of shapes, they begin to notice these shapes in their surroundings.  They see their plate as a circle and their napkin as a square when they eat dinner.  They look at the windows and doors in a room and recognize them as rectangles.  Tana Hoban’s book Shapes, Shapes, Shapes (1986) uses photographs of familiar objects such as pots and pans, and scenes such as construction sites, to present various shapes. Children will find more shapes on each page as they look at the photos again and again, and as they learn to name more shapes such as trapezoids and ovals.

An activity that can follow the introduction of this book can be allowing children along with family members to take photos of shapes in their home, their neighborhood or school.  They can display and compare the photos and name the shapes in each other’s photo.a door

In addition to two-dimensional, flat shapes, young children should be introduced to three-dimensional, fat shapes.  Reading the book, Changes, Changes (Hutchins, 1987), can open a child’s mind to the endless possibilities of how to arrange 3D blocks to build structures.  In this wordless picture book, a wooden couple builds a house but it catches on fire, so they must build a fire engine, then a boat to deal with all of the water, and so on.  Encourage children to find 3D objects in their environment such as food containers that represent cubes, cylinders, and rectangular prisms.  They can build their own structure with these containers and name them as they build.a pic of food boxes

Once children are familiar with the names of shapes, they can expand their vocabulary to include attributes of shapes.  The book, If You Were a Triangle (Aboff, 2010), includes illustrations of triangles that are slices of watermelon, Yield signs, faces of pyramids, designs on wallpaper, and more.  The text repeats the phrase, “If you were a triangle…” and lists attributes such as “three sides,” or “three corners” and introduces the terms polygon and angle.  At the end of the book, specific triangles are shown—equilateral, right and isosceles—along with examples of these triangles put together to form a new, composite, shape such as a rectangle or rhombus.  Children can look for triangles in their environment as well as practice putting the triangle Pattern Blocks together to form new shapes.a pic of 2 shapes red and greana pic of 2 shapes blue and green

Another concept children learn in early geometry is relative position.  Young children are gradually exposed to words used to describe the position of an object or person relative to other objects or people such as above, below, beside, in front of, behind, and next to.  Young children are also starting to distinguish between their right and left and are learning to move, and count, forward and backward.  A book that is fun for children to use to learn these concepts is Bug Dance (Murphy, 2002).  The bugs in this book go to school together and in gym class they learn a dance that teaches them to take steps to the right and to the left, then hop forward and backward.  Young children can perform the dance as the book is being read over and over.

After children have practiced their dance moves they can practice the terms in the book, as well as other position words, to describe the position of Pattern Blocks.  For example, children might say: the square is below the hexagon; the triangle is on the right of the square; the trapezoid is on the left of the square; the triangle is next to the square. a pic of 4 shapes

There are many children’s books that are written to introduce shapes, however many use the word “diamond” instead of rhombus.  I try to avoid these books or let children know a diamond shape is called a rhombus when we are learning math.

Virtual Pattern Blocks

If you don’t have any pattern blocks in your center just yet, the children can play with them virtually using this website. It is fairly simple to use; just click on the shape you want and drop it on the paper.  Once there, children can drag the shapes around to make geometric designs.

Some of these “click and drop sites” are great for children as they develop their hand-eye coordination, their fine-motor skills, and their visual perception skills.  Computer games should never take the place of actual playing with manipulatives, but they are a great enhancement to a play-based program.

Even if you don’t believe in computers in the classroom (I don’t- more on that later) they are here to stay.  Children will need to develop computer/navigation skills and mouse agility at some point and I would rather that children learn them on developmentally appropriate websites, than with some of the other stuff that is out there.

Pattern Blocks

Pattern blocks come in all sorts of sets.  There are beginner sets for younger children (I really like these), and there are larger sets for older children. They usually have small and large triangles, small and large squares, a rhombus or two, a few trapezoids, and some hexagons.  They most often come in a variety of colors.

Pattern blocks help children see shapes, manipulate shapes, create patterns, and explore geometry.

You can make your own pattern block cards so that children can match the shapes to the shape on the card.  There are also books of pattern block patterns that you can buy.  Some sets include them….Check out the one below.
