The number bonds to 10 are 6 pairs: 0 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5. Print one pair on a ten frame, or all 6 on one sheet.

From number bonds to 5 up to 10
5 has 3 pairs: 0 and 5, 1 and 4, 2 and 3. Double both parts of each and you have 3 of the pairs of 10: 0 and 10, 2 and 8, 4 and 6. The other 3 pairs of 10 have two odd parts: 1 and 9, 3 and 7, 5 and 5.
Why each pair sits on a ten frame
A ten frame is 2 rows of 5 squares. Fill the top row first and every number has one shape: 7 is a full row and 2 more, and the 3 empty squares are its partner, in plain view.
5 and 5 is the only pair with no turn-around, which is why 6 pairs make 11 questions, not 12.

Questions and answers
Is there a number bonds to 5 worksheet?
Yes. Choose All 3 pairs that make 5 and print: 6 large bonds, each pair asked twice, with the answer key as page 2. A single pair such as 2 and 3 prints its 6 questions, never one bond twice.
Does 0 and 10 count as a number bond to 10?
Yes, which is why there are 6 pairs and not 5. The Common Core asks kindergarten to find the partner of any number from 1 to 9 (K.OA.4), so choose Make 10 from 1 to 9 if you want zero left out.
What comes after the pairs that make 10?
Bonds to 20. Each pair of 10 gives one: add a ten to the 7, and 3 and 7 becomes 3 and 17. Then come the one-digit pairs past 10, where knowing 8 and 2 turns 8 + 6 into 10 + 4.
All 21 practice sets
The 6 pairs that make 10 6
0 and 10The empty frame and the full frame: 10 + 0 = 10 and 10 − 10 = 0. The Common Core make-10 standard runs from 1 to 9 (K.OA.4), so this is the extra pair. England asks year 1 pupils to realize the effect of adding or subtracting 0.
1 and 9On the frame, 9 is every square but 1, so the partner of 9 is found by looking, not counting. It is the pair behind adding 9: 9 + 4 = 9 + 1 + 3 = 10 + 3 = 13.
2 and 88 on the frame is a full row of 5 and 3 more, with 2 squares empty. The Common Core example of making ten uses this pair: 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14 (1.OA.6).
3 and 77 on the frame is a full row and 2 more, with 3 squares empty. The guidance for year 2 in England writes this pair 3 ways: 3 + 7 = 10, 10 − 7 = 3 and 7 = 10 − 3.
4 and 66 on the frame is a full row and 1 more. Slide that 1 counter across and 4 and 6 turns into 5 and 5: 4 + 6 = 5 + 5 = 10. The pair next to the double.
5 and 5The only double among the pairs of 10, and the only pair with no turn-around: swap the parts and nothing changes. On the frame it is 1 full row and 1 empty row. There are 3 ways to ask it, not 6.

The 3 pairs that make 5 3
0 and 5An empty five frame and a full one: 5 + 0 = 5. Common Core kindergarten writes 0 for a count of no objects (K.CC.3), and this is the first bond where that matters.
1 and 4Hold up one hand and fold the thumb down: 4 up, 1 down. Double both parts and you have a pair of 10, because 2 + 8 = 10.
2 and 3The Common Core example of splitting a number is this pair: 5 = 2 + 3 (K.OA.3). 5 is odd, so it has no double, and 2 and 3 is as close to equal as its parts get. Doubled, it is 4 and 6.
On a ten frame 3
Five frame: how many more to fill?One row of 5 squares, some with counters. 6 different frames, from empty to full. The small version to start on: the Common Core wants adding and subtracting within 5 fluent by the end of kindergarten (K.OA.5).
Ten frame: how many more to fill?A frame of 2 rows of 5 squares shows some counters, over a bond with 10 on top. The pupil writes the counters as one part and the empty squares as the other. 11 different frames, from empty (10 more) to full (0 more).
Two colors on a full frameEvery square holds a counter, some shaded and the rest open, so it prints in black and white. The pupil counts each kind and writes both parts under a 10. The shaded counters fill from the top left, so 7 is a full row and 2, never scattered. 9 frames.
Turn-arounds and ladders 4
Ladder of 56 bonds in order, from 0 and 5 to 5 and 0. Every bond has one even part and one odd part, because 5 is odd.
Ladder of 1011 bonds in order, from 0 and 10 to 10 and 0. The first part goes up by 1 as the second comes down by 1, so the whole never changes. In every bond both parts are even or both are odd.
Turn-arounds of 53 pairs, 6 ways: 5 is odd, so no pair is a double and every pair has a turn-around. Compare 10, where 6 pairs give only 11 ways.
Turn-arounds of 10Each pair is asked both ways round, so 3 and ? and 7 and ? are separate questions: 6 pairs, 11 ways, because 5 and 5 has no turn-around. The Common Core example of the rule: if 8 + 3 = 11 is known, then 3 + 8 = 11 is also known (1.OA.3).
Mixed drills 5
All 3 pairs that make 50 and 5, 1 and 4, 2 and 3. With only 3 pairs, a sheet of 6 bonds asks each one twice.
All 6 pairs that make 100 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5. One part is given and its partner is missing. With only 6 pairs, each one comes round twice on a 12-bond sheet.
Make 10 from 1 to 9The kindergarten standard to the letter: for any number from 1 to 9, find the number that makes 10 (K.OA.4). 9 questions, one for each given number, and zero never appears.
Pairs of 5 and pairs of 10 mixedHalf the bonds have 5 on top and half have 10, 9 pairs in all. Side by side the link shows: double both parts of a pair of 5 and you get a pair of 10, so 1 and 4 becomes 2 and 8.
Whole missing: is it 5 or 10?Both parts are given and the top circle is empty, and the answer is always 5 or 10. Quick to mark, and it shows who still counts from 1: the aim is to see 4 and 6 as 10 without counting.
