# Working Arithmetic

**Description**

The 170 lessons in Grade 2 are bound in 5 workbooks with tear-out pages. Unit 1 reviews addition and subtraction facts through 10 and other skills taught in Grade 1; Unit 2 teaches all the addition and subtraction facts for 11; Unit 3, the 12’s and 13’s and carrying and borrowing; Unit 4, the 14’s and 15’s; and Unit 5, the 16’s-18’s. Continuous review is built into the lessons and simple reading problems are practiced frequently. Speed drills are included in the workbooks. Money, time and measures are reviewed; half dollar, quarter hour, and pounds and ounces are introduced.

A set of blackline masters (optional) provides extra practice for the teacher to copy as needed. Simple multiplication and division are included in the blacklines for those classes that are ready for it in Grade 2.

The teacher’s manual comes in 2 hardcover volumes, Units 1 and 2 in Book 1, and Units 3-5 in Book 2. The manual is essential for class time instructions and for workbook directions. Pupil’s pages are shown in miniature with answers filled in.
