Making 1000 Practice Activities
Printable maths drills for practising number pairs and addition facts that make 1000 with speed, accuracy, and place value understanding.
Practice that builds confidence
Understanding complements to 1000
These Making 1000 practice activities help children build fluency with addition combinations that total 1000. They practise spotting complements such as 400 + 600, 750 + 250, and 999 + 1 while strengthening place value thinking.
The printable worksheets include focused maths drill formats where learners complete missing addends, match pairs, and solve quick addition facts. The activities are useful for revision, morning practice, homework, or extra support in the Addition section of Math Drills.
Making 1000 is more than memorising facts. Children learn that 1000 can be built from hundreds, tens, and ones, so 725 needs 275 because 700 + 200, 20 + 70, and 5 + 5 regroup neatly to 1000. This skill supports mental maths, column addition, subtraction, and estimation.
How the practice progresses
The worksheets move from friendly pairs such as 100 + 900 and 350 + 650 to less obvious combinations like 642 + 358. Some questions may ask for the missing number, while others ask children to choose or write the partner addend. This variety helps learners see patterns instead of counting up one by one.
A simple parent routine
At home, begin with ten oral questions using round hundreds. Then write one number, such as 480, and ask your child to explain how to reach 1000: 480 to 500 is 20, then 500 to 1000 is 500, so the answer is 520. Finish with a short worksheet section and ask the child to circle two problems they solved mentally.
Classroom uses for maths teachers
Teachers can use these sheets as warm-ups, quick fluency checks, remedial practice, or maths centre tasks. They also work well before lessons on subtraction from 1000, regrouping, or checking addition answers. Pair work is effective: one child gives a number and the other gives its complement to 1000.
Common errors to watch for
Many children find the hundreds correctly but forget the tens or ones, giving 725 + 375 instead of 725 + 275. Others treat 1000 like 100 and stop too early. Encourage them to check by adding the answer back to the first number and confirming the total is exactly 1000.

Why iBloom worksheets help
The iBloom activities give repeated, purposeful practice without clutter. A child-friendly strategy is: make the next hundred first, then make 1000. For 638, add 62 to reach 700, then 300 more, so the complement is 362.
