NOTE

THE Second Year continues the work of the First Year. Beginning with a thorough review of numbers up to 20, the book advances to numbers from 21 to 100.

Frequent drills are inserted to give the pupils a complete mastery of the combinations of these numbers.

Denominate numbers are introduced with pictures of measures in common use.

The problems are designed to relieve the monotony of the abstract number work. Alternations of oral and written work also afford variety.

Pictures and other features of the first book are continued, to render the book attractive.
