With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

Young mathematicians review fact families and create a Math Fact Family Tree. This clever lesson plan includes some excellent printouts that support the instructional activity.

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...

The article for this lesson no longer accessible through the links in the lesson plan, but can be found in the National Center for Biotechnology Information website. After reading it, environmental science students answer questions and...

The first activity in this resource has learners computing the mean and standard deviation of two different data sets and drawing conclusions based on their results. The second activity has them using a dice-rolling simulation to...

Fifth graders become familiar with problem solving strategies of guess and check and working backwards. They demonstrate the basic concepts of addition, subtraction, multiplication, and division using a math sentence.

Students investigate the concepts of volume for rectangular prisms and spheres. They measure the volume of one balloon and then consider how many breaths it would take to fill the room with balloons. The rectangular prism being measured...

How can we estimate the answers when working with decimals? That's what the question is as the class reviews two-digit decimal addition. Have them estimate by rounding to a whole number either before or after they have completed their...

Students apply math skills to determining how much corn seed to plant in 100 acres. They compute the amount of weed killer needed and after totaling how many bushels per acre they harvest, they calculate their profits.

In this scientific notation instructional activity, students read about the discovery of new planets. They use scientific notation to identify the number of miles from one planet to the next. Students determine how long it would take to...

Students count collections of coins and one-dollar bills. They solve problems and learn to use the dollar sign ($) with the decimal point to represent money amounts. This activity is important as a foundation for future math concepts in...

Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

Five problems provide practice for learners to find the area of a circle given the distance of the radius. Answers on the key use pi as a variable and do not include fully computed numeric answers. To reinforce basic multiplication facts...

Geometers find the area of four circles given their circumferences. Circumference is presented in the form of "numeral (diameter) x pi"; the answer key shows solutions as  "numeral (radius squared) x pi," so computation is...

You are what you eat! Your statisticians keep a log of what they eat from anywhere between a day to more than a week, keeping track of a variety of nutritional information using a spreadsheet. After analyzing their own data, individuals...

A question to ask your class is, How fast is your Internet? That depends on the data transfer rate (DTR), which is the unit rate used in this activity. Math students will calculate how long it takes to download a music file and a video...

In this Euler's method activity, students compute the successive approximations for a given function. They compute the piecewise linear function to produce the approximation to the solution of the initial value problem. This four-page...

Students study operations with real numbers using mental computation or paper-and-pencil calculations. They judge the reasonableness of numerical computations and their results. They set up and solve proportions for direct and inverse...

In this math worksheet, students find the area of shapes by counting the number of grid paper squares inside each shape. This is a worksheet generator, the teacher controls the complexity of the shapes as well as the grid size. Answers...

Young scholars examine composition of dirty bomb and its possible effects on a city, and investigate simulations of such an event; students use computational and problem solving skills to assess damage and prepare report proposing...

Fifth graders locate different time zones. In this time zones instructional activity, 5th graders label the different time zones. Students research the different ways man has kept time throughout history. Students also compute the...

In this adding prices of items worksheet, students choose items and add their totals using mental math, paper and pencil, and the calculator.
