This activity allows two users to play a game of order of operations where each player tries to connect four game pieces in a row before his or her opponent does. The players can choose to answer problems which use addition / subtraction, multiplication / division, exponents, and parentheses. They can also choose the difficulty level. The learner tab provides useful information to students on using order of operations. The instructor section includes classroom advice, links to standards and textbooks, and related activities including a printable quiz.

Two shapes are provided to create the given fractions, once they are correctly made a third box appears to create an additional fraction that sits between the original amounts on the number line. Be sure to check out the instructor tab for an explorations worksheet, links to standards, classroom suggestions, and additional similar resources.

In the Classroom
Provide students with the printable explorations worksheet to practice creating and ordering fractions. Introduce the site on your interactive whiteboard or projector as an introduction to comparing and ordering fractions. Have students take turns manipulating the whiteboard as they learn the site (and new skills). This activity would work well for individual or pairs of students to use on classroom computers. Provide this link on your class website for students to access both in and out of the classroom.Add your comments below (available only to members) | Become a Member
