Second graders complete a variety of activities surrounding a unit on China and Chinese culture.

Ninth graders, after being given a unique scenario and a task sheet on Dead Man's Curve, calculate and explain the force needed to keep a car on a curve using a set of formulas and a geometric property of circles. They utilize and create...

In this plane figure worksheet, students solve a total of 6 riddle problems related to identifying polygons using given information.

In this exploring area worksheet, students sharpen their problem solving skills as they solve 6 story problems using the provided diagrams.

In this numbers and sequences worksheet, students solve problems presented in six different activities.  Extension problems are also provided.

In this 2 D shape worksheet, 2nd graders find 2 D shape words in a word search. Students search for 13 shapes and are given a word bank at the bottom.

Students calculate the area of a parallelogram. In this geometry activity, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

4th-5th graders will compete in a game similar to Jeopardy in which they answer questions from a variety of subject areas including science, language, and math. The questions are based on an extremely wide variety of topics, so would be...

Third graders become more familiar with various geometric shapes by completing the games and activities in this lesson plan. They keep track of the number of each shape they use in each of the three ways.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Young scholars experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate...

Students construct a convincing argument that the same amount of fabric is needed for each color of quilt being made in a specific design. They justify the relationship between vertical angles and the sum of the interior angles. Students

Third graders represent fractions as part of a whole. In this fractions lesson plan, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson plan includes individual practice and an assessment instead of...

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Students study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.

Students use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .

In this math worksheet, students find the solutions to the problems that involve solving equations with and without rational expressions.

In this shape worksheet, students determine which shapes can be put into which pictures of diagrams, marking the correct diagrams, 6 shapes total. A reference web site is given for additional activities.

Explore finding and measuring perimeter of figures.

[Free Registration/Login may be required to access all resource tools.] This study guide reviews the formulas for area and perimeter of triangles and different kinds of quadrilaterals.

Use a "linkage strip" to build triangles with different side lengths. When you build a triangle, see if you can deform it into a different triangle while keeping the side lengths the same.

The goal of this task is to study if the analog of the AA criterion for similarity of triangles holds for different types of quadrilaterals. Aligns with HSG-SRT.A.2.

In this lesson, middle schoolers explore properties of triangles. They fold paper to make a triangle and measure its angles. Students also draw triangles with given conditions. Included are examples, discussion questions, and closing...
