Open up your hands like a book. Number your fingers 1-10 and hold identical fingers up to show an 11, while tucking the rest under in your fist. Say the sum out loud.

11 - 1 the 10 thumb will be standing
FINGER-ITH-MA-TRICK
1 + 10 = 11
10 + 1= 11
11 - 1 = 10
1 1- 10 = 1

2+ 9 = 11
9 + 2 = 11
11- 2 = 9
11- 9 =2
3 + 8 = 11
8 + 3 =11
11- 3 = 8
11- 8 = 3
4 + 7 = 11
7 + 4 =11
11- 4 = 7
11- 7 = 4

5 + 6 = 11
6 + 5 =11
11- 5 = 6
11- 6 = 5

When Frances More visits your school to teach your students and teachers about her amazing Fingerithmatic Multi Sensory system, she will also demonstrates this very clever trick to children to show them how wonderful the fingers are at mathematics.
Fingerithmatic is different from Fingerithmatrick although it uses the fingers to hold and remember all the times tables patterns and how to build to higher levels.
After school parents are invited to the school library or hall for a small fee to learn this concept for themselves in order to understand how it works so they are able to visualize the same patterns as their children have just learned.
Teachers are taught these and many more mathematical processes during their professional development program.
