A complete practice book of addition and subtraction word problems for Standard I and Standard II. Fifteen carefully graded sets take children from numbers within 20 to numbers within 99. Each set has four parts: addition, subtraction, mixed problems, and two-step problems. Children write the number sentence and the answer for every question. A full answer key is included at the end.

**Back-cover blurb**
Young mathematicians do not begin with long sums. They begin with a story.

*Anaya has 13 books. She gets 7 more. How many books does she have now?*

This book gives children 600 such stories — short, clear, and graded so the numbers grow gently. Sets 1–5 stay mostly within 20 for early Standard I. Sets 6–10 move toward 50. Sets 11–15 reach 99 for Standard II.

Every practice set has four parts:

- Set A — Addition word problems
- Set B — Subtraction word problems
- Set C — Mixed word problems
- Set D — Two-step word problems

On every page the child must do two things: write the number sentence, then write the answer. Clue words are taught at the start. A drawing box invites dots, sticks, and simple pictures when a child needs to see the sum. Parents and teachers can use one full set (A–D) as a weekly worksheet. The complete answer key — including both steps for Set D — is printed at the end of the book.

Built for home and school. Written for children who are learning to think in numbers.
