Addition and Subtraction Word Problems Within 20 | 50 Mixed Problems | 1st Grade Math

Ribbit — ESL/EFL Worksheet Resource

This 10-page pack of mixed addition and subtraction word problems for 1st grade has 50 one-step problems with numbers up to 20. Every page has 5 problems, each three short lines long with a small black-and-white picture and an empty answer box: "Mia has 9 apples. She gets 5 more apples. How many apples does she have?" or "There are 17 birds in a tree. 4 birds fly away. How many birds are left?" Adding and taking away are mixed on every page, so students have to read for the action words (gets, finds, more come, fly away, are eaten) instead of assuming the operation. The header on every page reminds them to show their work. Starting numbers run from 8 to 20 and answers stay at 20 or below. The pages have no answer key.
