Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.

Young scholars solve problems involving area. In this geometry lesson, students calculate the area of an object and relate it to the area of the ocean. They define what exactly and area is and then solve problems relating to the real world.

Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.

For this Algebra II worksheet, 11th graders solve nonlinear inequalities, graph the solution set on the number line, and write the solution in interval notation.  The one page worksheet contains thirty-eight problems.  Answers...

Students solve problems using the metric system. In this algebra lesson, students convert between the metric system and the Imperial system. They use these two systems to solve real life problems.

Fourth graders investigate patterns and sequences.  In this patterns and sequences lesson, 4th graders use a hundreds chart to build recurring patterns.  Students skip count by threes and fives on a hundreds chart by coloring...

Third graders find areas of rectangles by using square units, apply knowledge to real-life situations, and simplify method of counting square units by multiplying the length times the width.

A multi-step problem has learners finding the actual area based on a scale drawing and then converting units at the end. Two different solution choices are listed depending on the preference on which step to start first. Both methods can...

Kindergarteners use worms, puppets or other props to practice counting to 100. First, they listen to a read aloud of Count Worms by Roger Hargeaves. A worm pattern is used to count to 100, with each segment of the worm...

Students study the Manduca bug and its growth data. They look for patterns and compare their own growth rate to that of the Manduca.

Learners engage in a study of mean, median, mode, and range in order to represent data in tables. They are also exposed to the results of data that is skewed because of the outlier.

Students test the strength and speed of their Manduca. They keep their insect in a small dish and wiegh it down with pennies. They share their observations with the class.

Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

Eighth graders explore problem solving strategies to build a paper bridge with a partner. As a class they discuss a variety of techniques to solve a simple problem, then in pairs construct the longest non-supported single span bridge...

Tenth graders investigate volume in class and in the real world. They explore volume of cylinders and prisms as it relates to different subjects. Pupils also investigate how important volume is in different career field.

Students investigate properties of circles. For this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Students explore how objects stay the same size and only "look" like they change when closer are farther from the object. They sequence aerial photos and satellite images from closest to farthest.

Students construct a simple refracting telescope. They calculate the magnification.

Eighth graders compare the volume of three cylinders constructed from the same size sheet of paper. They use concrete and graphical models to derive formulas for finding perimeter, circumference, area, and volume of two and three...

Origami is an excellent way to combine Japanese culture, art, and geometric shapes into one engaging instructional activity! Scholars begin by listening to the story Sadako and the Thousand Paper Cranes and learn the origin of...

First graders use nonstandard measurement to measure. After reading Inch by Inch, 1st graders pair measure leaves that they have collected. They glue their leaves onto tag board to make a display.

Fourth graders measure cups, quarts, and liters.

Fourth graders practice measuring different objects in inches. Individually, they estimate the length of the same object in centimeters and then calculate the actual length. They compare and contrast their estimate to the actual length...

Seventh graders experiment with measurement as it relates to the algorithm for dividing fractions. For this fractions lesson, 7th graders work in groups to establish how many post-it notes it takes to fill an 8 X 11 piece of paper. Using...
