Students find the sum of the angles of a polygon and construct a polygon given the number of sides. In this polygon lesson plan, students draw large polygons on the floor of the room. They measure the length of each side and the interior...

For this magnification worksheet, students read about how lenses magnify images and how to determine the magnification of an image. Students divide ten by the focal length which is found to be the measurement from the center of the lens...

Third graders examine the non-standard method of measurement and compare it to the metric system of measurement. In this introductory module lesson, 3rd graders discover the scientific observation. Students also develop communication...

Third graders explore the concept of linear measurements and how they work. Coins are used to reinforce the process.

Sixth graders investigate metric measurements. In this metric measurement activity, 6th graders explore mass, capacity, and length. Students examine graduated cylinders and balance scales to obtain measurements. Resources are provided.

Third graders create a shipping box from a cardboard material. In this measuring lesson, 3rd graders read the book Henry's Freedom Box and discuss the main idea. In the story a slave ships himself to freedom and the students measure and...

Students measure respiratory rates on live toads, and the effect water temperature has on their findings.  In this scientific method lesson, students record their findings and present them in a graph, comparing the results.

Young mathematicians work to recognize the relationship between their scale models of the Joides research vessel and the real vessel. They calculate the relationships between various parts of the ship using fractions, ratios, and...

Stop the summer lag with a set of second grade Common Core based math practice sheets. Learners fill in hundreds charts with missing numbers up to 1,000. They practice writing numbers in standard, expanded, and word form. Children also...

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...

How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...

Is foot length to forearm length a linear association? The class collects data of fellow scholars' foot length and the length of their forearms. They plot the data and find a line of best fit. Using that line, they make predictions of...

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

If you're looking for some perimeter practice problems for beginners, you've found them! Learners reference an example that takes them through the steps of finding the perimeter of a square or rectangle. Then, they complete nine on their...

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...

How long of a line can you draw within this activity? Learners pick two points outside and within the map to create the longest line they can. After drawing 10 lines, learners plot the length of each line on a line plot. Then they...

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

In 2006, New Horizons began its mission to fly to Pluto. As it continues its journey, scholars track its progress with the help of an informative website, all the while reinforcing measurement concepts with the construction of a scaled...

Scholars explore triangles with rods of different lengths. Using rods of 2, 4, 6, 8, and 10 cm class members build as many different types of triangles as they can. They also describe properties of these triangles and determine...

How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Getting the right measurements can save a lot of time and money in the real world. Learners are introduced to unit conversion and how to accurately go from one unit to another. The first pages are notes and then the packet finishes with...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

It's always nice to hear from friends. Your budding mathematicians read letters from pen pals and convert customary measurements into metric units and vice versa. They also write letters to an imaginary pen pal using metric units.
