Third Grade Math Ideas

    Birthday Bar Graph

    • Third-grade students begin to learn about the process of collecting and displaying data. One of the simplest ways to do this is to create a bar graph. In a fun project, have the students collect data from their classmates about which month of the year they were born. Then, each student must draw a bar graph to represent the data they have collected. Students then will be able to see which months have the most birthdays throughout the classroom.

    Fraction Collage

    • Third-grade students are beginning to learn about the concept of fractions, and this project will help them understand fractions in a visual sense. Assign students different fractions --such as 2/3 or 3/4. Have them cut out a sheet of construction paper equal to the denominator of the fraction. For instance, for 2/3, a student would cut out a 3-inch strip of construction paper. Then, have them cut out 1-inch squares on a different color paper equal to the numerator. Place the strips on the denominator strip. This will help them visualize the fractions.

    Race to 100

    • In third grade, students must build upon the knowledge they learned in first and second grades. This includes honing mental math skills. For a fun math activity, have two students sit down with a pair of dice. One student must roll the dice and add the two numbers together and write them down. The other student must do the same. Taking turns, the students must see who gets to the number 100 first. This requires them to use mental math, and double-digit addition as well.

    Geometry Art

    • Introducing the concept of geometry is also a good idea in the third grade. To help students understand the shapes, pass out a variety of shapes to each student--including a square, rectangle and pentagon. Then, using toothpicks, have the students outline the different shapes. This will help them visualize and understand the different geometric shapes, and help them be better prepared for future geometry lessons.
