Description
Word problems help first graders see that addition is a tool for real life, not just numbers on a page. When students read a short math story, pick out the numbers, and decide to add, they practice reading and math at the same time. This Addition Problem Solving Addends to 40 Worksheet gives students steady practice adding a two-digit number up to 40 and a one-digit number or a group of ten, which is exactly the kind of mental math first grade asks for.
This 1st grade addition worksheet has five short math stories about shells, stickers, toy blocks, apples, and ducks. Students read each story, add the two numbers, and write the answer with its unit in the box, such as 35 blocks. Some problems make a new ten, and others add a group of ten, so students practice both strategies. A friendly picture of a sand pail, a toy box, and a picnic basket ties the page to the stories. Use it for math centers, small groups, homework, or a quick check after a lesson on adding tens and ones.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- 5 addition word problems with answer boxes
Here are three reasons this worksheet helps children learn. First, each story uses short sentences and familiar words, so early readers can focus on the math. Second, the numbers are chosen to practice two key first-grade strategies: making a ten and adding a multiple of ten. Third, writing the unit with each answer teaches students to check that their answer makes sense in the story.
Teachers and parents can extend the lesson with simple activities. Act out a story with real blocks or crayons, then write the number sentence together. Use base-ten blocks or a hundred chart to show how 27 plus 8 crosses the next ten. Ask students to write their own story using two numbers from the page, then trade with a partner to solve. You can also review the Addition Problem Solving Addends to 40 Worksheet answers aloud and ask each child to explain how they added.
