3rd Grade Math Activity: Circles in the Sand
Watch this fun animation all about circles. Learn all about the radius, diameter and circumference of circles and the amazing “almost magic” trick to measuring the circumference of any circle, large or small. When you’re done, see if you can recreate this activity at home or at the beach. Do you get the same results?
This interactive activity is embedded in our Third Grade Math + 3 (Purple) course.
This research-based course focuses on computational fluency, conceptual understanding, and problem-solving. The engaging course features new graphics, learning tools, and games; adaptive activities that help struggling students master concepts and skills before moving on; and more support for Learning Coaches to guide their students to success. This course for students in Grade 3 provides a quick overview of whole number addition and subtraction, but has a greater focus on whole number multiplication and division, encompassing early algebraic thinking. Decimals are studied in relationship to place value and money, and fractions are addressed through multiple representations and probability. Students are introduced to specific methods and strategies to help them become more effective problem solvers. Geometry and measurement are addressed through the study of two- and three-dimensional shapes, early work with perimeter, area, and volume, and applying measuring techniques to time, length, capacity, and weight.
