Cut several one-inch squares out of a variety of colored construction paper. Provide students with a large sheet of paper and the one-inch squares. Ask students to create a mosaic picture by gluing exactly 100 squares on the paper, using at least three colors. When they have finished their picture, have the students count the number of squares they used in each color. They must then write the fraction that represents the portion of each color in their picture. For example, if a student's picture has 25 red squares, he would write the fraction 25/100 and reduce it to 1/4.
The book "Picture Pie" by Ed Emberley shows how a circle can be divided into several different fractions. Read it with your students and then provide them with several circles cut out of construction paper. Ask the students to cut the circles into a variety of fractions. For example, cut one circle into halves, another into fourths and another into eighths. They can then use those fraction pieces to create a picture by gluing them onto another large piece of paper.
Provide students with five sheets of construction paper in different colors. One sheet will represent a whole, so have students label it with a "1." This will be the body of the "fraction man." Ask students to cut another sheet of paper into two equal parts and label them "1/2." Glue one of the halves at the top of the whole sheet of paper to be the head. Have students cut a third sheet of paper into four equal parts and label each with a "1/4." These pieces will be the arms and legs of the man. Show students how to cut another piece of paper into eighths and label them "1/8." Glue two of these pieces onto each arm and leg to become hands and feet. Ask the students to cut the last piece of paper into 16 equal parts and label them "1/16." Glue two of these pieces onto each hand and foot to become fingers and toes.
Divide your students into groups of three or four students. Provide each group with several sugar cubes, frosting and plastic knives. Instruct students to use the sugar cubes to build a pyramid, using the frosting to stick the cubes together. Once the pyramid is built, ask students to count the number of cubes used to make each layer of the pyramid. They must then label each cube with the fraction it represents of that layer using a pencil to write on the sugar cubes. For example, if the bottom layer of the pyramid contains 20 sugar cubes, each cube should be labeled "1/20."
