What K.CC.4 Means in Plain English

Kindergartners count 6 shells by touching each one once while saying one number name, then answer “how many?” with “six” rather than counting again. Spread the shells out or count from the other end and the answer is still six, and one more shell makes seven.

This is the idea the rest of the number work stands on. Counting out a given number of objects (K.CC.5), comparing two groups (K.CC.6) and adding by counting on (1.OA.5) all assume the child trusts that the last number said is the amount.

K.CC.4 I Can Statements

  • I can touch each object once and say one number for it.
  • I can tell how many without counting again.
  • I can say that the next number means one more.

K.CC.4 Worked Example

Six shells counted three ways, so the three parts of the standard show up one after another.

Problem

Put 6 shells in a row. Count them, then spread them out and count again, then add one shell.

Six shells, counted and counted again
  1. Touch one shell and say one number. Move to the next shell only after you have said a name for this one.1, 2, 3, 4, 5, 6
  2. The last number said tells how many. Ask “how many shells?” and the child answers without recounting.6 shells
  3. Spread the shells into a messy pile and count again, starting from a different shell.1, 2, 3, 4, 5, 6 ... still 6
  4. Add one shell. The next number name is the new amount, no need to start over.6, then one more is 7
Answer6 shells, and 7 after one more is added

Check it: Put the 7 shells in a row and count from the other end. The last number is 7 again.

Common Mistakes with K.CC.4

Counting faster than touching

“1, 2, 3, 4, 5, 6, 7” said over 5 crayons, the voice running ahead of the finger

Try this: Have the child slide each object across a line as its number is said, so one word moves one object.

Recounting to answer how many

Counts to 6, is asked “how many?”, and counts 1 to 6 all over again

Try this: Cover the objects right after the count and ask how many are under your hand, so the last number has to do the work.

Spread out means more

Six shells in a row are “6”, the same shells spread across the table are “more”

Try this: Count the row, spread the shells while the child watches, and count again to show the number stayed the same.

Where K.CC.4 Fits

Comes BeforeK.CC.1Know the number names in order, which is the sequence this standard attaches to objects.
AlongsideK.CC.5Count up to 20 objects in a line, array or circle to answer how many.K.CC.3Write the numeral that shows how many.
Comes NextK.CC.6Compare two groups by matching or counting.1.OA.5Add and subtract by counting on or back, like 6 + 2 by saying 7, 8.
