Allow the children to sit in a circle. Pass around a basket with objects in it. Say a word and ask the child to choose an object from the basket that matches the word. Write three words or draw three objects on a chalk board. Ask a child to erase the word or object that does not rhyme with the other two words.
Show worksheets to children that have pictures of rhyming words. Ask the child to match the words that rhyme. Cut and paste worksheets are also effective. Show the child how to match, cut and paste pictures of objects that rhyme onto a sheet of paper.
Read a nursery rhyme to a child. Ask the child to pick out the words that rhyme. For instance, if the sentence is, "Jack and Jill went up the hill." Ask the child which words rhyme in the sentence.
