Third Grade


Third grade students are inquisitive. They are more engaged with in-class discussions and continue to progress with cross-curricular learning, critical thinking, and reading skills. They also use grammar, vocabulary, and writing skills to communicate their results in various subjects. These cross-curricular opportunities help build a solid foundation that will benefit our students throughout their education and in life.

St. Mary’s has three third grade classrooms each with a preferred maximum of 20 students. In addition to the following subjects, our students have weekly specials classes including art, computer/technology, library/media center, music, PE, and Spanish. 

Below is a brief highlight of our third grade curriculum. Instruction will be differentiated based on students' academic levels and learning styles. This is achieved through engaging activities, manipulatives, and technology resources in areas such as math, reading, science, and Spanish. For complete curriculum standards, please visit the Diocese of Savannah Catholic Schools Curriculum.

MATH – Students represent and solve problems involving multiplication and division, understand properties of multiplication and the relationship between multiplication and division, and multiply and divide within 100. Students also solve problems involving the four operations, identify and describe patterns in math, and use place value understanding and properties of operations to perform multi-digit math.

Students develop an understanding of fractions as numbers, solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects, and represent and interpret data. Students also study geometric measurement including concepts of areas and relating areas of multiplication and addition, recognize perimeter as an attribute of plane figures, distinguish between linear and area measures, and reason with shapes and their attributes.

LANGUAGE ARTS – Students engage in listening to and reading various literary genres, apply phonics/spelling/syllabication rules, demonstrate ongoing development in fluency and expression during oral reading, apply reading strategies to monitor comprehension, demonstrate ongoing development in vocabulary, identify literary elements, distinguish between types of sentences and the basic parts of speech, and further develop writing skills.

RELIGION – Our students further explore the Blessed Trinity, Christ as the center of our lives, guidance of the Holy Spirit, the knowledge of the faith, Mary as the Mother of God and the Church, Liturgical life, moral formation, Ten Commandments, prayer, how Saints model Christian living, and missionary spirit.

SCIENCE – Students apply the scientific method to all scientific investigations, discover how heat is produced and the effects of heating and cooling and changes in temperature, manipulate magnets to show how they affect other magnets and common objects, compare and contrast habitats of different organisms and the dependence of organisms on their habitats, compare and contrast the physical attributes of rocks and minerals, interpret fossils as evidence of organisms that lived long ago, and recognize and relate the effects of pollution and humans on the environment.

SOCIAL STUDIES – Students learn to locate major topographical features, describe the cultural and geographic systems associated with historical figures, apply economic principles of supply and demand, explore connections with various communities and their cultural contributions to the development of the community, explain the political roots of our modern United States democracy, discuss the lives of Americans who expanded people’s rights and freedoms in our democracy, and identify and locate U.S. states. Students also learn to apply the basic principles of personal savings and spending.
