Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Can you follow a composition of transformations, or better yet construct them? Young mathematicians analyze the composition of dilations, examining both the scale factor and centers of dilations. They discover relationships for both...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-instructional activity series supports children with learning how to measure the area of squares,...

All hail the king! Young mathematicians put their skills to the test as they strive to become the king of math.

A geometry module connects algebraic reasoning to geometry. It challenges scholars to investigate the slope criteria for parallel and perpendicular lines, prove theorems involving coordinate geometry, and write equations for circles and...

Where does a circular table fit best? Individuals move a circle representing a table into different quadrants of a room. Pupils determine which equation of the circle will place the table in the appropriate quadrant. A discussion...

Put the tree back in geometry! Explore shapes and celebrate Christmas while using pentagon, square, and triangle pattern blocks to create a Christmas tree.

Add some holiday cheer to geometry practice with a Christmas themed pattern block mat in the shape of a wreath. 

Calculate galactic orbits in a far-out resource. Pupils drag a point on a circle to graph the orbit of a fictional planet. Using the equation, they find points through which the orbit passes. To finish the simulation, users determine the...

How many bones can a dog on a leash reach? Class members move a dog on the end of its leash and determine whether it can reach bones located at specific points. The learners see whether the bone lies on the circle or outside of the...

Five questions make up an interactive designed to promote math skills involving the division of fractions. To assist in the process, a tool with moveable parts showcases how fractions are flipped. Question types include multiple-choice,...

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...

Young mathematicians use their geometry skills to save the Land of Venn in an engaging math game. A fun way to reinforce children's understanding of basic geometric figures and shapes.

Count on the scale to enlarge a figure. The video shows how to create an enlargement given a scale factor and a center of enlargement. The presenter multiplies the vertical and horizontal distance by the scale factor to find the new...

Work on drawing and identifying triangles with a math worksheet. After kindergartners trace triangles at the top of the page, they draw their own versions underneath, and color the triangles that are hidden amid other geometric shapes.

Five word-problems challenge mathematicians to add fractions. Interactive fraction circles assist scholars in problem-solving. Question types include multiple-choice, true or false, and a discussion.
