Two Sets of Addition Worksheets Up to 100 (With Answer Sheets!) — Perfect for Grade 4–5 Students
If your learners are ready for a much bigger challenge, these Addition Up to 100 worksheet sets are exactly what you need. Designed for older elementary students, especially Grades 4–5, these worksheets help build strong number fluency and prepare kids for multi-digit addition, regrouping, and eventually multiplication and long division.
I’ve created two complete sets, and each set includes 100 worksheets PLUS 100 answer sheets —
200 pages per set, and 400 total pages across both sets.
These worksheets are ideal for teachers, homeschooling families, parents of older learners, and tutors who want structured, consistent practice with larger numbers.
Why Addition Up to 100 Is Important for Upper Elementary
By Grades 4–5, students need to be comfortable adding higher numbers accurately and with confidence. Practicing addition up to 100 helps learners:
- Strengthen mental math for larger values
- Prepare for multi-digit addition with regrouping
- Develop number sense needed for fractions and decimals
- Build accuracy and speed
- Gain confidence before tackling more complex math
This level of practice is perfect for students who are ready to go beyond basic addition.
How Each Set Is Organized
Both sets follow the same easy-to-use format:
✔ Odd-numbered pages = Worksheets
Each worksheet includes:
- 10 addition problems
- Sums up to 100
- Name field
- Date field
- Score box
✔ Even-numbered pages = Answer Sheets
Every worksheet is immediately followed by its matching answer key.
This keeps grading quick and makes self-checking simple (if desired).
All worksheets in both sets are unique due to randomized problem generation.
What’s Included in Each Set
Set 1 (200 pages total)
- 100 worksheets
- 100 answer sheets
- All problems unique and randomly generated
Set 2 (200 pages total)
- 100 additional worksheets
- 100 additional answer sheets
- A fresh set of 100 randomized problem pages
Across both sets combined:
200 worksheets + 200 answer sheets = 400 total pages
Who These Worksheets Are Designed For
Teachers (Grades 4–5)
Perfect for warm-ups, independent work, extra practice, homework, or review before moving into multi-digit addition and regrouping.
Homeschoolers
A ready-made resource for daily math work. Easy to use, no prep, and answer sheets included for quick correction.
Parents

The answer sheets right after each worksheet make the whole process smooth and efficient.
Why Answer Sheets Matter Even More for Big-Number Addition
With larger sums, mistakes are more common — and answer sheets help:
- Save grading time
- Ensure corrections are accurate
- Support self-checking routines
- Make tutoring more efficient
- Keep homeschool work organized
They’re a major convenience, especially with 200 worksheets per set.
