6th-8th Grade Math Activity: Interactive Protractor
A protractor is an instrument that measures the angle between two lines. Practice using a protractor by placing it on the point where the lines meet and measuring the angle. Click on the dark blue bar at the bottom of the protractor to drag it into position. Measure the angle, then type your answer in the box to check it.

Students enhance computational and problem-solving skills while learning topics in algebra, geometry, probability, and statistics. They solve expressions and equations in the context of perimeter, area, and volume problems while further developing computational skills with fractions and decimals. The study of plane and solid figures includes construction and transformations of figures. Also in the context of problem solving, students add, subtract, multiply, and divide positive and negative integers and solve problems involving ratios, proportions, and percents, including simple and compound interest, rates, discount, tax, and tip problems. They learn multiple representations for communicating information, such as graphs on the coordinate plane, statistical data and displays, as well as the results of probability and sampling experiments. They investigate patterns involving addition, multiplication, and exponents, and apply number theory and computation to mathematical puzzles.
