Write the missing number in the circle.

Practice and check

Worked example

The two parts add to the whole. Subtract a known part to find a missing part.

3 + 2 = 5

  1. 3 + 2 = 5
Check answers after trying

1: 3 + 2 = 5 2: 2 + 6 = 8 3: 6 + 1 = 7 4: 1 + 5 = 6 5: 1 + 4 = 5 6: 1 + 5 = 6 7: 5 + 3 = 8 8: 1 + 6 = 7 9: 2 + 5 = 7

Tips for Parents

▸ Why It Matters This sheet keeps the same combine-two-parts-into-a-total layout as the easier version but raises the totals up to 8, and several problems pair a small number like 1 with a larger one like 5 or 6 — so your child needs to be comfortable starting from the bigger number rather than always counting from scratch. Five of the nine problems here put 1 right next to a bigger partner, which is intentional repetition: it gives your child many chances, in one sitting, to notice that starting from the larger pile and counting on just a little is faster and less error-prone than starting over from one every single time. Review questions: 5 · Number Bonds 01 - Combining Numbers (Easy). ▸ Getting Started For a pair like 1 and 6, encourage your child to start at the larger number and count on just once — "6... 7" — rather than counting both piles from 1, which is slower and more error-prone at this size. You can make this concrete with real objects: put six blocks in one hand and one in the other, say "six" while holding up the big group, then touch the single block and count "seven." Doing this with fingers, buttons, or snacks first, before moving to the abstract circles on the page, helps many children make the leap from counting-all to counting-on without frustration. ▸ If They Get Stuck If the learner is unsure where to write, follow the two lines from the given upper numbers to the empty lower circle. That lower circle is the total. For the actual pair 2 and 6, put out two groups of counters, combine them and count eight. Alternatively, start at 6 and say 7, 8 while moving two counters. Both methods are valid. If counting on is confusing, return to counting all the counters; speed is not required. Check the answer by adding the two upper numbers again. ▸ Praise Points Praise your child for starting from the bigger number on a pair like 2 and 6 — choosing the more efficient counting-on strategy over counting everything from one is exactly the growth this worksheet is checking for. It's also worth noticing out loud when they catch and fix their own mistake, since self-correction is a stronger sign of understanding than getting every answer right on the first try. Even a simple "I saw you start from six instead of one — that's exactly what mathematicians do!" reinforces the strategy far more than praise for speed or a perfect page.

What This Worksheet Builds

Nine sums range from 5 to 8. Five problems include 1: problems 3, 4, 5, 6 and 8. Add the upper numbers and write the total below; counting all or counting on are both usable strategies.

Next Step

If ready for totals up to 10, try Combining Numbers 03, which includes 1 + 9 and 2 + 8. Keep the same upper-parts/lower-total layout. Use counters again whenever needed.
