  • sink
  • think

  • chunk


  • Tank or bowl
  • Picture of a tank 
  • Chunks of objects (wood, paper, styrofoam, rock, eraser, plastic)

Tell the children they will dunk and plunk things in the tank while they read and write words that end in –nk. Make a list of words ending in –nk: plink, plunk, sink, sank, sunk, dunk, chunk.

Literacy Activities
Dunk a hunk into a tank

  • Show the children a tank or a picture of a tank and a bowl of water to use as a pretend tank.
  • Tear objects into hunks and chunks.
  • Plunk the hunks and chunks into the water and listen to the sound they make (e.g., plink, clunk, thunk, kerplunk).
  • Have the children make a guess – Do you think it will sink? Do you think it will not sink? Wink if you think it will sink. Blink if you think it will not sink.
  • Check to see if the hunks sunk or if they did not sink.
  • Have the children write a sentence about what happened with each hunk. (e.g., “We dunked the hunk and it sank!” “We plunked the chunk and it did not sink.”)

More Practice
Phonological Awareness/Word Building:

  • With word blending cards, have the children make new words by changing the vowel or the beginning consonant:
    • sank --> tank; clink --> plink; plunk --> clunk; dunk --> hunk; blink --> wink
    • clink --> clank --> clunk; plunk --> plink --> plank; sink --> sunk --> sank
  • Read target words in texts 
  • Engage the children in reading the text Plink Plunk Sunk together as a class/group.
  • Read the text again fading support.
  • Ask the children to look for words ending in –nk as you read the text together.
  • Have the children make a list of the –nk words in the text.

Write about the activity using target words/patterns

  • Give each child a whiteboard and have them write words from dictation, changing one or two letters each time to make a new word: crank, clank, blank, bank, sank, sink, slink, clink, plink, plunk, plank, thank
  • Give each child a paper and pencil and let them write about what they did with hunks and chunks. Have them include some of these words: hunk, chunk, sink, sank, sunk, plunk, dunk, wink, or blink.
