Number Bonds to 5: The First Part-Part-Whole Page

Every bond on this Kindergarten worksheet has the same whole: 5. Six part-part-whole diagrams fill the page, each one a large whole circle joined to two smaller part circles, and beneath the numeral in the whole circle runs a row of five counting dots. One part is printed; the other is a dashed, empty circle. The child counts the dots, sees how many of them the printed part already accounts for, and writes the number that finishes five.

Five is the right whole for a first bond page because it can still be held in the hand and taken in at a glance. A child who cannot yet recall that 3 and 2 make 5 is not stuck here: they count the dots, cover the printed part with a finger, and count what is left, so the picture does the teaching while the number knowledge catches up. That bridge from counting to knowing is the entire purpose of the dots. It is also why five comes before ten — there are only two pairs to meet, they come round again and again, and most children start finishing the bonds from memory within a page or two.

Print the PDF free and let the counting happen out loud; it fades on its own once the pairs are known. When the bonds of five arrive without a pause, number bonds within 10 widens the range one whole at a time, and the make ten page brings the dots back for the pairs every first grader eventually needs by heart.
