Curated OER
Triangles
In this triangles worksheet, 10th graders solve 3 extensive informal geometry problems that involve triangles. First, they sketch a triangle, selecting 3 of the sides and constructing 3 midpoints. Students then draw each of 3 medians by...
Curated OER
Three- and Two- Dimensional Geometry
In this three- and two- dimensional geometry learning exercise, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of...
Curated OER
Ratios, Rates and Percentages
In this ratios, rates and percentages worksheet, 6th graders solve 16 different types of problems that include writing each ratio as a decimal and a fraction in lowest terms as a percent. They also arrange numbers in ascending order and...
Curated OER
Perimeter and Area
In this perimeter and area worksheet, 9th graders solve 17 various types of problems, mostly word problems related to determining the area or perimeter of a geometric shape. They also determine the area and perimeter of shaded portions...
Math Mammoth
Area Problems
In this area worksheet, students solve eight area problems to solve involving triangles, quilts, and land plots. Students have to know area formulas for right triangles.
Math Mammoth
Angles in a Triangle 2
Youngsters draw specified angles when given measurements of other angles and discover traits of angles in similar triangles. This one-page worksheet contains six multi-step problems.
Math Mammoth
Area Problems/ Triangles
In this math activity, students find the area of each triangle that is described in the word problem. They calculate the area through using the formula of 1/2 Base X Height.
Math Mammoth
Classify The Triangles
In this math learning exercise, students measure all the angles in these triangles. They also calculate the sum of the angles and classify the triangles.
Curated OER
Triangle Foldable
For this math worksheet, students cut out six cards with the names of different triangles. Triangles include equilateral, scalene, and isosceles.
Math Mammoth
Triangles 1
In this triangles worksheet, students measure and calculate the measurements of eight triangles, their sums and classify the triangles as acute, obtuse or right.
Curated OER
Triangle Puzzler
For this math worksheet, students analyze a chart and identify the names of 9 types of triangles. Students also find as many kinds of triangles they can in a given figure.
Curated OER
Shapes
Students practice identifying spheres, triangles, and rectangles and the difference between plane shapes and space shapes. They identify shapes in the classroom and complete activity sheets.
Curated OER
Pythagoreum Theorem
Students practice assessing how to apply the formulas for the area of parallelograms and triangles. They recount the contributions of Pythagoras and apply the theories of the Pythagorean theorem in a group project to calculate the...
Curated OER
Figure Analysis
Students identify the importance of the Principles and Elements of design through self-analysis and sketching clothing appropriate for their body type. They write the actual color name on a line of the included sheet, then describe why...
Curated OER
The Truth About Triangles And Proofs
Learners engage in a lesson that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the importance of...
Curated OER
Similarity and Congruence
Students determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
Curated OER
Transforming Triangles
Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...
Curated OER
Optical Illusion
Students practice creating optical illusions as well as discerning how perception of information may change its characteristics. They distinguish between an equilateral triangle, endpoints, vertices's, and segments of triangles. The...
Curated OER
Exploring Characteristics of Triangles
Learners draw triangles and explore the classification of each using the measures of interior angles and lengths of sides. They investigate the sum of the interior angles of various triangles and conjecture and prove the theorem: The...
Curated OER
Exploring Centers of a Triangle: Part 2
Students model and solve a real-world problem by constructing the centroid of a triangle. They explore relationships of the medians of a triangle and investigate how the centroid partitions each of the medians. Students investigate...
Curated OER
Pythagorean Theorem Spreadsheet
Studetns use a spreadsheet to organize data on the sides of a triangle. They use the Pythagorean Theorem and the If then spreadsheet function to decide whether the three sides determine a right triangle. Students work individual...
Curated OER
Geometry and Quilting
Learners create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...
Curated OER
Tiling the Plaza (Geometry)
Students make patterns with a variety of pattern blocks. Pupils experiment with making tile designs using only one shape by rotating that shape around a point. They enter a contest for creating the best tile design for the new plaza...
Curated OER
Pythagorean Theorem
Eighth graders draw right triangles and identify the parts of a right triangle: right angle, interior and exterior angles, hypotenuse and legs. They predict and identify any relationships that exist between the sides of a right...
