Students estimate the area of states using the formulas for the areas of rectangles, squares, and triangles. In this geometric shapes lesson, students divide irregular shaped states into shapes. They use the formulas for areas of...

Students make a prediction. In this applied science lesson, students guess the number of items in a jar. Students create a bar graph to show the predictions and the actual amounts.

An excellent way to reinforce math vocabulary in your classroom! Seventy-eight posters focus on number and number sense, computation and estimation, measurement, geometry, probability and statistics, and patterns, functions, and algebra.

Pupils solve problems using estimation and exact calculations. In this algebra lesson, students use gum balls and thread to create hands on manipulatives to solve problems. They calculate the average of their total data.

In this introduction to approximation theory, students compute the slope and intercept of a line. They describe nonlinear relationships. This four page worksheet contains approximately five problems.

In this math computation review for grade 5 worksheet, 5th graders answer 25 multiple choice mixed problems with the answer key included.

In this local linearity instructional activity, students identify the slope of a line tangent to the graph at a given point. They use linear approximation to estimate values. Students determine the slope of a secant line at a given...

In this linear approximation learning exercise, students determine the derivative of a function and explore properties of the error when using a tangent line to approximate a function graph. This two-page learning exercise contains four...

In this differentiation learning exercise, students find an equation of a line tangent to a curve. They use linear approximation to estimate answers. This two-page learning exercise contains approximately 12 multi-step problems.

In this second grade math problem solving worksheet, 2nd graders draw pictures to solve three addition and subtraction problems.

Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate...

In this estimating products worksheet, students interpret data on the yearly diets of the average American, then solve 6 word problems where they must estimate products by rounding the larger factor to its greatest place value.

For this differentiability worksheet, students write expressions for a tangent line approximation to a graph, determine the limits, and use Taylor's theorem to differentiate given functions. This three-page worksheet contains a...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Sometimes dealing with decimals is so much easier than dealing with fractions. The ninth instructional activity in a 21-part module has the class consider situations when it might be easier to add or subtract fractions by first...

Compute fuel economy and gas mileage. Why? So you can teach rates and ratios, of course! Middle schoolers calculate the rate of miles per gallon for various vehicles. They research each vehicle, its mileage per gallon, and cost per...

Estimating the value of numbers is much harder than it sounds! Scholars compare and order the value of numbers presented in different forms including fractions, decimals, roots, integers, and pi. This builds on the previous lessons in...

This Groundhog's Day, challenge scholars to predict, estimate, tally, and graph in a weather-themed lesson in which class members play the role of the groundhog to forecast the weather come February second. 

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Many math concepts are covered through this resource: percentages, decimals, ratios, exponential functions, graphing, rounding, order of operations, estimation, and solving equations. Colorful worksheets and a link to a Google search for...

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Your learners will enjoy playing a game as a motivator to learning and remembering the adding and subtracting of fractions.

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

The learner puts reasoning and estimation to work. The directions are to place a decimal in the answer to make the equation true. Pupils are to look at the two problems, one multiplication and one division, and estimate an answer. No...
