Addition Fact Fluency by Grade
Kindergarten
Sums to 5 and 10. Use Easy mode with 20 problems per page. Focus on understanding that addition means "putting together."
Grade 1–2
Sums to 20. Use Easy or Medium difficulty. Aim for automatic recall of all facts — students should not be counting on fingers by the end of grade 2.
Grade 3+
Two- and three-digit addition. Use Hard mode (0–100) or set a Custom range (e.g. 20–99) to drill larger number addition without regrouping or with regrouping.
Tips for Teaching Addition
Timed Practice
Give students 3–5 minutes to complete 30 problems. Record scores over time to show improvement and build confidence.
Doubles and Near-Doubles
Use the Custom range to generate problems where both numbers are the same (e.g. 4+4, 7+7). Doubles are often the first facts students memorise.
Making Ten
Set Custom min/max to produce problems that sum to 10 (e.g. 3+7, 6+4). "Making ten" is a key mental maths strategy.
Homework Sets
Generate multiple pages — each has a different random order, so students can't copy from each other. Include the date line for accountability.
Frequently Asked Questions
Are the problems randomly generated each time?
Yes — every time you click Preview, a completely new set of problems is generated. Each page of a multi-page PDF also has a different random set, so no two pages are identical.
What paper size does the PDF use?
The PDF is formatted for US Letter (8.5 × 11 inches). It will also print on A4 paper with slight scaling applied automatically by your printer or PDF viewer.
Can I add a class name or custom title?
Yes — use the Worksheet Title field to enter any text you like, such as "Ms Johnson's Class — Week 3 Addition" and it will appear at the top of every page.
