## Five-Count Part 4.1: Common patterns for "10s" in a group counting process

#### Created by Sho Sengoku, 2001

A "finding 10s" in a group counting process can be even faster when you memorize common patterns that make 10s. Since you can skip those multiplication like 3 × 4 or 5 × 3 and addition like 8 + 12, finding one 10 or 20 can be done in even less than one second.

During a group counting process, what matter are a group number and a number of checkers in the group, not a pip count of each point in a group. You should forget or ignore those alternately colored triangles, and just focus on those group boundaries like this six box image:

 Group # 5 4 3 Group # 0 1 2
The tables below show you some very common patterns for 10s, which you often find in backgammon games in a real life.
