It is something I immediately fell in love with in and I have seen my kiddos math thinking grow by leaps and bounds. They are no longer just math "do-ers," they are math "thinkers. There is no way that I could explain CGI in a blog post.

A league-average PER is always PER takes into account accomplishments, such as field goals, free throws, 3-pointers, assists, rebounds, blocks and steals, and negative results, such as missed shots, turnovers and personal fouls.

The formula adds positive stats and subtracts negative ones through a statistical point value system. The rating for each player is then adjusted to a per-minute basis so that, for example, substitutes can be compared with starters in playing time debates.

For example, Bruce Bowenwidely regarded as one of the best defenders in the NBA at least through the —07 seasonhas routinely posted single-digit PERs.

PER has been said to reward inefficient shooting.

Cognitively Guided Instruction (CGI) is a student-centered approach to teaching math. It starts with what your students already know and builds on their natural number sense and intuitive approaches to . View Scope and Sequence for Kindergarten View Scope and Sequence for Grades 1 - 8 Click for new eResource Info Arithmetic Developed Daily is a fast and efficient lesson starter designed to review key math skills and concepts. - Elementary Arithmetic - High School Math - College Algebra - Trigonometry - Geometry - Calculus But let's start at the beginning and work our way up through the various areas of math. We need a good foundation of each area to build upon for the next level.

A three point field goal made is worth 2. A missed field goal, though, costs a team 0. Given these values, with a bit of math we can show that a player will break even on his two point field goal attempts if he hits on On three pointers the break-even point is If a player exceeds these thresholds, and virtually every NBA player does so with respect to two-point shots, the more he shoots the higher his value in PERs.

So a player can be an inefficient scorer and simply inflate his value by taking a large number of shots. He made this assumption because he forgot that PER is calibrated against the rest of the league at the end of the formula. Actually, if we took a player that was completely average in every other respect for the —07 season—rebounds, free throws, assists, turnovers, etc.

As long-time PER fans know, that would make him considerably worse than nearly every player in the league. To end up with a league-average PER of Reference guide[ edit ] Hollinger has set up PER so that the league average, every season, is 1.

Introduction. Physics is an experimental science, and as such the experimental basis for any physical theory is extremely important. The relationship between theory and experiments in modern science is a multi-edged sword. 1. The best math ematicians amongst the snake family: the adders.: 2.

My math class started working on 2D shapes, but I lost interest. It was just too plane. 3. I have problems with math but with chemistry, I have solutions.: 4.

A teacher harshly corrected a student on a math problem. I guess he got schooled. 5. I know a math ematician who could not afford to buy lunch.

Using CGI, teachers start with what children already know about math and build on it to move them toward deeper levels of understanding.

Children solve problems in ways that make sense to them using real-world contexts. During problem solving, multiple strategies are shared, honored and highlighted. Amby's Education Resources -- Math Resources. Appetizers and Lessons for Mathematics and Reason Math for the Literate: Topics in .
