Fold these shapes in half and you'll have perfectly equal sides. Kids explore symmetry by completing 16 abstract shapes which have been cut off at the line of symmetry. They draw the mirror image, using several examples as reference. An...

Guide young mathematicians through the crazy world of negative numbers with a handy reference document. Offering clear instructions for adding and subtracting positive and negative integers, this resource is a great way to...

Fifth graders imagine an aquarium filled with 1,000 fish on a math worksheet. They express each species as a fraction of the total number of fish in the tank. Students reduce each fraction to lowest terms and then express them as...

Learning about proportions through measuring and mapping distances is the focus of this real-world math lesson that doubles as an activity. Mathematicians complete a course designed to measure and map locations in order to put the...

Pupils multiply the vertical and horizontal distances from the center of dilation by the scale factor. The independent practice prompts the class to analyze the relationship between the image and pre-image. The lesson is...

Colorado would probably object if Wyoming enlarged its borders. Scholars use an interactive map to change the borders of U.S. states to see how angles change. They then answer questions about regular and irregular polygons.

Scholars build upon their knowledge of scale drawings by using percents to represent the scale factor. Individuals work with scaling in vertical, horizontal, and both directions.

Lower young mathematicians' affective filter with a problem solving presentation that details four steps to make word problems appear less daunting. 

As the saying goes, a penny saved is a penny earned. Young scholars use a penny activity to earn their way to an understanding of volume. Given three different-sized cylindrical containers, individuals make calculations to determine the...

Scholars make a giant scale model of an object. They will take a regular item and enlarge it to five times its length and width. They attempt this same concepts with a 3D model.

Students explore perimeter. In this geometry and measurement lesson, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

Students practice calculating dimensions of rectangles in a photograph activity. In this rectangle dimensions lesson, students complete the 'Making a Photographic Enlargement handout and watch a video about scaling up photographs....

Did your students forget to bring their protractors to class again? Using this resourceful copy of four identical protractors, you can easily make a class set or let your students take them home. 

Students explore regrouping. In this hands-on math place value lesson, students construct models using connecting cubes and place value mats to solve simple addition problems that require regrouping.

Students create a work of art based on a theme showing skill in pencil shading. They create a work of art showing value contrast to center of interest. They use math concepts to enlarge a composition using a grid.

Seventh graders watch a video and enlarge and shrink scale by applying proportional thinking. They practice measuring, using percentages, computing area, and problem solving.

A simple instructional activity with pictures of drums in a 100-chart format. Have your learners count the drums, and identify where the drums are that correspond to numbers ending in zero and five. Enlarge on a copier to 11x17 sized...

Middle and high schoolers solve fifteen problems from six exercise sets covering transformations, reflections, rotations, and enlargements. The solutions are provided.

Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Your geometry learners will appreciate this net for a square pyramid. Copy, cut, and manipulate to explore the surface area or volume of a square pyramid.

Spin the wheel of the fraction contraption and learn about equivalent fractions! After constructing their own spinners, kids use printable pizzas to represent fractions that are equal in value.

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.
