Vietnamese can be a difficult language to learn due to the change in tones when diacritic marks are added. Use this poem to review the five tones daily. You may enlarge it and hang it on the board as an anchor chart. Use it as a quick review during circle time or as a part of daily calendar activities. As your students hear the differences in each rhyme, through repetition, they will begin to internalize the symbols in relation to its tone. You may also print and copy for each student to have in their writing folder as a quick reference or to conserve paper you can also print and laminate a class set to use year after year.
