Adding Tens and Ones Worksheet – 1st Grade Addition & Base 10 Practice

The Adding Tens and Ones Worksheet gives first grade students focused, no-prep practice with addition. It is a print-and-go math page that fits easily into a mini-lesson, a center rotation, or a quick review day.

Learning objective: Students will practice addition and apply the skill independently by completing each task on the page.

Why it works: Each page targets one skill, so students get meaningful repetition without feeling overwhelmed. The layout is clean and uncluttered, which helps young learners focus on the task instead of the decorations.

What's included:

• 1 printable worksheet page

• Clear, student-friendly directions

• 3 practice sections (Part A to Part C)

• Answer key (1 page)

• Cover page

How it's organized: The page opens with these directions: "Add the tens and ones. Count the blocks and write the sum." The practice is split into 3 parts, so students can work through it in clear steps.

Grade level: Designed for first grade students. It also works well for kindergarten and second grade students who need extra practice or a fresh review.

How to use it: Assign it after a mini-lesson, use it in a small group, send it home as homework, keep it in your sub folder, or use it as a quick formative check.

Answer key: An answer key is included, so you can check work quickly or let students self-correct.

Teaching tips and variations:

• Use it as an exit ticket the day after a addition lesson to see who needs more support.

• Send it home as homework so families can see what their child is learning in math.

• Slip the page into a sheet protector so students can practice again with dry-erase markers.
