Frequently Asked Questions Thousands of web sites for educators and students. Support for long-term classroom planning and professional development. Information covering important topics for today's educators and parents. Each lesson demonstrates a mathematical skill that is then shown in a real world application. For example, in a section on Triangles, the technology extension activity demonstrates the use of a calculator to average data.
Students toss two number cubes to find an ordered pair which they graph on the coordinate plane.
They then measure the angle formed by a ray through the point, the origin, and the x-axis. As they repeat the experiment ten times, they record the ordered pairs and resulting angles in a table, averaging the angles when they finish. For example, in a lab on Investigating Decimal Division, students start by modeling decimal division on 10x10 grids and continue by finding patterns in the division of decimals by using calculators and the long division algorithm. Assessment options include mastery of skills, proficiency problem solving, promotion of communication, and preparation for standardized assessment. The teachers' edition includes a scope and sequence for the series as well as various charts, organizers, and lesson suggestions to aid teachers in implementing and customizing the course for their students.
