Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Customers often want ribbon around fancy cakes, but how does a baker know how much ribbon to buy? Scholars view a cake with multiple layers in different geometric shapes. They must figure the perimeter and circumference and add them...

In this math instructional activity, students investigate simple geometric shapes in the world around them. Students examine 3 detailed pictures which contain many shapes, then answer 7 questions about the picture. Then students complete...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

In this geometric solids activity, students examine 4 different solid shapes then record the number of faces, the number of edges and the name of each shape.

In this problem solving instructional activity, students calculate the missing angles and lengths to 4 different shapes. Students place their answers in the boxes provided.

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Scholars play against three other participants to show what they know about geometric figures. Starting at the beginning, kangaroos jump from shape to shape to match the figure to the displayed word and make their way to the finish...

Add a touch of holiday cheer to pattern block practice with a mat featuring a Christmas wreath. As kindergartners work on their shape identification and pattern completion skills, they create a beautifully festive picture.

Students tackle the problem of how to divide a triangular piece of land fairly among four people. They decide whether their method of fair division always works or if it only works in special cases.

Challenge young mathematicians' understanding of symmetry. Provided with images of different shapes, letters, and national flags, students are tasked with identifying the lines of symmetry and order of rotational symmetry...

Ten quadrilaterals make up two pages that can be cut, laminated, and made into a pack. The opportunities are endless with this resource!

Here is an assessment designed to test mathematicians' knowledge of writing numbers, comparing numbers, skip counting, solving addition and subtraction problems; along with measuring objects, telling time, identifying shapes, reading...

This is a mid-module assessment for the 16th lesson in 29 geometry lessons. Individuals demonstrate their understanding of concepts such as vertical and adjacent angles, constructing geometric figures, and triangle congruence criteria.

Need to know if your students comprehend all the Common Core standards covered in second grade? This growth assessment will let you know.  Find out if your second graders can add/subtract, tell the time, read a bar graph, know their...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Students explore ocean ecosystems. In this cross curriculum art and oceans lesson, students create a collage featuring three-finger algae using sand paper, tissue paper, and construction paper.

Learners create books about shapes.  In this shape lesson, students select a topic such as points, lines, angles, planes, polygons, quadrilaterals, triangles, circles, and polyhedra.  In groups, they create an illustrated...

Students design recreational equipment for a community. In this architecture lesson, students work in pairs to design the equipment. Students select materials and begin designing. Students assess themselves with a pre-made rubric.

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...
