Students use an online dictionaries to define key geometric terms. They explore several websites to help them differentiate the terms reflections, translations and rotations as they apply to geometry and then complete an assessment...

Students transform polygons.  In this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.

In this reflection, rotation and translation learning exercise, students describe which of the above happens to a set of shapes, and in what order. A reference web site is given for additional activities.

In this rotation, reflection and translation activity, students look at shapes on a grid and determine what happens to the shape, in order. A reference web site is given for additional activities.

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Increase the level of assessment rigor with the test of performance tasks. Topics include similar triangles, trigonometric ratios, Law of Sines, Law of Cosines, and trigonometric problem solving. 

Transform your learners into master geometers with an activity that asks them to first complete an assessment task drawing the result after transformation of a given shape in the coordinate plane. They then use cards to...

Do your students have what it takes to be the king of math? Find out with this fun skills practice game that covers a wide range of topics from counting and basic operations to measurement and fractions.

The 10th lesson in a series of 32, continues with the geometry of arithmetic of complex numbers focusing on multiplication. Class members find the effects of multiplying a complex number by a real number, an imaginary number, and another...

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

Students examine the concepts of geometry used by Paul Goble in his book Adopted By The Eagles. After analyzing Mr. Goble's work they create an original piece featuring symmetry, pattern, repetition, and other principles of 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...

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

In this reflections and symmetry worksheet, students draw lines of symmetry in shapes and patterns and reflect letters over lines in graphs. Students complete 20 problems.

In this similar triangles activity, students find the scale factor of 6 sets of similar triangles. Students find the scale factor of two similar triangles given a sketch with measurements. Students use proportions to find a missing side...

Fifth graders examine the many uses of coordinate grids. In this graphing instructional activity, 5th graders write data driven equations, discuss the x and y-axis, and determine if using 2 or 3 ordered pairs is better.  Students...

Students create a quilt, using different patterns. In this geometry lesson, students apply prior knowledge as they use different patterns to help them create a quilt using transformations and geometric shapes.

Students talk about mathematical language.  In this talking about your name lesson, students use the letters in their own name to review math vocabulary and concepts.  

Here is a geometry worksheet in which learners locate and identify various vocabulary terms related to geometry. There are twelve words located in the puzzle.

What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

In this reflection, translation and rotation worksheet, students determine which of these things have been done to s set of figures. A reference web site is given for additional activities.

In this reflection, rotation and translation worksheet, students determine which has been done to a set of 6 figures. A reference web site is given for additional activities.

Transform your lesson on transformations. Learners use given congruent triangles and tracing paper to determine the single transformation that carries one to the other. The concept is extended to combinations of transformations to...
