Negotiating can be a win/win experience if the involved parties apply the skills and techniques offered in a instructional activity about negotiating to settle differences.

For this geometry lesson, 10th graders break down a circle and identify the different parts. They discuss chords, diameter, radius, circumference, major and minor segment. There are 42 problems broken down into 5 different sections.

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

Use a unit approach in developing a fraction division strategy. The teacher leads a discussion on division containing units, resulting in a connection between the units and like denominators. Pupils develop a rule in dividing fractions...

Three levels of practice assure scholar mastery of vector addition. After inputting an incorrect answer, another problem replaces it so everyone finds success. The lesson works as one part of a series on vectors and projectiles.

Students compare the situation of Latin American immigrants with the situation of immigrants from other areas of the world. They use media to obtain information on topics of academic interest, personal interest, and intellectual interest.
