6 Digit Addition Practice Activities
Printable 6 digit addition practice for building accuracy with large-number column addition, regrouping and Indian place value.
Practice that builds confidence
What children practise
These 6 digit addition worksheets help children build accuracy with large numbers in the Addition section of Mathematics > Math Drills. Learners practise adding numbers in the lakhs, ten-thousands, thousands, hundreds, tens and ones places, with and without regrouping.
The printable activities use clear vertical sums, space for carrying, mixed drill sets and neat layouts for easy checking. They are useful for regular maths practice when children are ready to move beyond 5 digit addition and need confidence handling six-place addends.
Six digit addition extends familiar column addition to numbers such as 2,45,381 + 3,12,406. Children line up digits by place value, add from ones to lakhs, and record carries clearly. Some sums may create a 7 digit total, so the worksheets also strengthen understanding of the next place after lakhs.

Progression through the drills
Start with a small set of no-regrouping problems so the child can focus on alignment. Move to sums where carrying occurs in one place, then several places, and finally mixed practice. Encourage children to say the place names aloud: ones, tens, hundreds, thousands, ten-thousands, lakhs. This prevents them from treating a long number as a string of unrelated digits.
Simple parent routine
At home, choose one page or one row at a time. Ask your child to copy one problem neatly, estimate whether the answer should be close to 5 lakh, 8 lakh, or another sensible amount, and then solve. After checking, let the child circle any column where a carry was used. If an error appears, rework only that column first instead of erasing the whole sum.

Classroom uses for teachers
Teachers can use these printables for warm-up maths drills, independent practice, homework, or quick remediation after teaching large-number addition. They also work well in centres: one group solves, another checks with a partner, and a third explains the regrouping steps using place-value language.

Common errors to watch for
The most frequent mistakes are misaligned columns, forgotten carries, adding from the left, and writing a carry in the answer row. Children may also drop a zero in the middle of a number or forget that a total above 9,99,999 needs a new digit at the left.

Why iBloom worksheets help
iBloom layouts keep the focus on calculation: roomy columns, consistent formatting and enough variation to reveal whether the child truly understands regrouping. A child-friendly strategy is “line up, add up, carry up, check back”: align by place, add from ones, write carries above the next column, then reread the answer using Indian place value.
