For this trigonometry word problem worksheet, students calculate how close a ship comes to a lighthouse.  The solution with explanation is provided.

Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Students practice solving very basic number sentences and recording their answers on a worksheet. Individually, they use different manipulatives to represent the sentence they solved. They also explain what steps were taken to solve...

It's not so straightforward — lines can model a variety of applications. Pupils experience linear relationships within the context of science, including Hooke's and Ohm's Laws. Class members got a taste of motion and speed from the...

Learners discuss and review examples of the Pythagorean Theorem using a GSP, Geometer's Sketchpad, activity.

Students use logical arguments and inductive reasoning to make or disprove conjectures. After observing a teacher led demonstration, students discover that the deductive process narrows facts to a few possible conclusions. In groups,...

Pupils collect and analyze data. In this statistics lesson, learners create a scatter plot from their collected data. They use, tables and graphs to analyze the data and mae decisions.

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

Does it? Kids find the perimeter and area of different shapes to assess whether their rectangle has guts. In addition to finding the area of a rectangle, learners work to find the area of a trapezoid. All worksheets are included. 

Investigate simplifying rational expressions. Learners define rational expressions, review how numerators and denominators are polynomials and complete several problems using a checklist to ensure they don't skip any steps. Work can be...

Students practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a graph,...

Young statisticians are introduced to box plots and quartiles. They use an activity and discussion with supplemental exercises to help them explore how data can be graphically represented.

Learners compare and contrast two routes selected for a virtual field trip. They create a data table of educational activities, lodging, and meal costs using Microsoft Excel software.

Are we there yet?  Young trip planners learn about their state and plan a trip. They will select sites to see in three cities in their state, and record associated costs in a spreadsheet. While this was originally designed as a...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Pupils build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using logs.

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

Students investigate the origin of the quadratic function. In this algebra instructional activity, students analyze solving an equation by completing the square. They compare the early methods as compared to our method for solving...

Students calculate the amount of greenhouse gases they produce in a given day. Using an equation, they determine the emissions for different sized vehicles and calculate the amount resulting from a family vacation. They create a class...

Young scholars investigate the first Peter the Mint Eagle, who lived at the Philadelphia Mint from 1830 to 1836. They determine how many months Peter was there and use pictures, numbers, equations, and/or words to explain how they came...

Students participate in a math activity that reinforces basic fact strategies including counting on from a greater number. They interact with pictures of hot-air balloons and discuss word and sentence equations that deal with how many...

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

This unit is about making calculations in the real life situations of taxis, hire cars, and cell phones. They find and justify a word formula which represents a given practical situation. Solve simple linear equations such as 2? + 4 = 16.
