Asian languages uses explicit number names 26 is said “two-ten six” 11 new words needed
to count 1 to 100
Among the many advantages Chinese have for superior performance in mathematics, explicit language may play a role.

English speaking children learn 26 new words or word parts to count to 100
Place value is a separate topic of study for many years in the curriculum
Spanish speakers have 28 new words or word parts to learn
Most children from both language heritages score at or below average in international testing.

Refer to the meaning of the number rather than the traditional name
Use of straws, linking cubes, other small items that can be bundled or used singly
Every number named by its meaning Calendar work Counting Time Measure (c) Judith E. Beauford, 2009
