Practice and check

Worked example

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

5 + 1 = 6

  1. 5 + 1 = 6
Check answers after trying

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

Tips for Parents

▸ Why It Matters This sheet flips the structure of the Number Bonds worksheets — both small numbers sit on top already filled in, and the blank circle is on the bottom, so your child combines two known parts into a total rather than splitting a whole apart. With totals no higher than 6, it's a gentle first introduction to that "put together" direction, exactly the move addition asks for later on. Nine problems fill this page, each pairing two small numbers between 1 and 5, giving plenty of low-pressure repetition — the goal is comfort with the operation's direction, not speed or memorized facts. ▸ Getting Started Have your child point to each filled-in top circle and say both numbers first — "3 and 2" — before writing anything below, so the addition happens on purpose rather than as a guess. A useful habit is saying the whole sentence out loud together, "3 and 2 make...", letting your child supply the answer before picking up the pencil. Some children like tracing a small arc with a finger from one top circle to the other and down to the bottom one. If your child already knows a total by heart — 2 and 2, say — let them write it right away instead of counting every time. ▸ If They Get Stuck If your child isn't sure how to combine two circles like 4 and 2, have them count that many fingers on each hand separately, then count all the raised fingers together in one sweep. When ten fingers aren't enough, small objects like buttons or coins work just as well; grouping them into two piles before sliding them together often makes the "joining" idea click. A child who resists finger-counting can draw tally marks under each number and count them all at once instead. Try not to correct a wrong answer right away — ask "can you show me how you got that?" first, to see where the counting went off track. ▸ Praise Points Praise your child for writing the total in the bottom circle without hesitating over which spot is the "answer" — since this sheet puts the blank in a different place than the Number Bonds worksheets, getting comfortable with that format is worth calling out. It's also worth noticing when your child recognizes a repeated pair, like spotting 1 and 2 twice on the page and already knowing the total is 3 the second time — an early sign facts are becoming automatic.

What This Worksheet Builds

Flips the bonds format around: two small parts (1-5) are already filled in on top, and the child adds them to find the total (up to 6) in the bottom circle — the first introduction to addition as 'putting together' rather than splitting apart. Nine short problems build repetition without ever exceeding a total of 6, keeping the mental load light while the direction of the operation becomes familiar and comfortable.

Next Step

Once totaling two given parts feels automatic, move on to Number Bonds - Combining Numbers 02, where totals rise to 8 and some pairs mix a very small number with a larger one. That wider spread of totals and less evenly matched pairs is the natural next challenge once your child is confidently reading both top circles before writing anything below.
