This resource will help assess your students' mastery of concepts surrounding measurement and time. This worksheet will challenge your third graders with problems on area, perimeter, measurement, and elapsed time problems.
Fourth graders will discover the building blocks of geometry in this unit: points, lines, line segments and rays. Students will explore the properties of different shapes, including symmetry, parallel and perpendicular lines, and 900 angles. Students will apply their understanding as they learn to sort shapes based on these properties.
Geometry in third grade introduces kids to the idea that shapes have different categories (rectangles, rhombuses, etc..) attributes (four-sided, etc...) and areas of different values. This lesson, designed by our curriculum experts, provides the guided instruction and practice that third graders need to conceptualize shapes in a deeper way. For more practice, download and print the third grade geometry worksheets recommended as part of this lesson.
Your students will have a blast as they use perimeter in a real-world scenario to plan their very own carnivals in the school gym. Students will choose their activities and use their calculated dimensions to map our their carnival on the provided graph.
Perimeter is another geometric concept that your child will begin learning in third grade. Perimeter is defined as the distance around a two-dimensional shape. Calculating perimeter requires addition and multiplication skills, so after your student has mastered those concepts, you can help them move on to our worksheet resources for perimeter.
Perimeter is the total length around a shape, and for different shapes, there are different ways to calculate it.
Square: perimeter = 4 × s, where s is the length of a side
Rectangle: perimeter = 2 × (w + h), where w is width and h is height
Triangle: perimeter = a + b + c, where a, b, and c are the lengths of three different sides
Circle: the perimeter for a circle is actually called the circumference. Circumference = 2 × π × r, where r is the radius.
Quadrilateral: perimeter = a + b + c + d, where a, b, c, and d are lengths of different sides
If you want to learn more about the different shapes, you can check out our geometry page to get a better idea of what circles are and the different polygons you can calculate the perimeter of.
After you practice your perimeter skills with the resources on this page, you can then move over to our area resources to learn how to calculate the amount of space inside a shape.
