Light and sound are the running themes of a read-aloud anthology. Over three weeks, third graders listen to discuss readings in preparation for completing extension activities. Pupils work through the writing process to compose an...

Create the perfect prom night image using the Law of Reflection! An interactive lesson explores angles of reflection when looking in a full-length mirror. Learners change the distance from the mirror and length of the mirror and watch...

How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

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...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

How does something go from here to there? Describe it with a transformation. Young mathematicians learn how to translate, reflect, rotate, and dilate an image. 

Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.

Explore a geometric sequence model through a simulation. Learners change the starting drop height of a ball and watch how the heights of following bounces change. They consider the ratio of the consecutive bounces as they analyze...

What's the difference between body cells and sex cells? Learners explore the question and the process of meiosis using an interactive lesson. An animation describes the discovery of meiosis and describes its phases for a detailed and...

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs students to an understanding of this crucial mathematical...

Bring about the change you want to see in the world  or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Acting as journalists on a team to determine the most influential city-state of Renaissance Italy, your young historians will research, discuss, and compare the rise of Venice, Florence, and Genoa, and their influence in shaping a...

Put together the pieces and model a parabola. Learners work through several examples to develop an understanding of a parabola graphically and algebraically.
