Word Ladders were first created in the late 1800’s by Lewis Carroll, as a two-person game. The original game was called Doublets. Players were given the beginning word and the ending word, like head – tail. Each player had five moves to change the first word into the last word. Players were only allowed to change one letter of the previous word to create their next word or move toward the target word.
There are a few differences between the original word ladder game played in the late 1800s and the Word Ladder curriculum developed by Dr. Timothy Rasinski. One difference is that only the beginning word is given. Another difference is that Rasinski ladders usually require more than five moves. Another difference is that solvers of the “puzzle” must use a clue and the previously developed word to discover the next word in the puzzle. Another difference is that Rasinski’s Word Ladder allows for different amounts of letter changes, instead of a set amount. The clue states how many letters need to be added or subtracted to the previous word of the puzzle to form the new word. Another difference is that there may be different amounts of letters within a word in the same puzzle. The puzzle shows solvers how many letters are in the word that they are solving for. Rasinski’s Word Ladders are published as literacy curriculum for students in Grades K-6. Each ladder has a focus or topic.
The benefits of using Word Ladders are many. Word Ladders usually help to increase student knowledge of spelling—encoding of words. Students must think about the letter order of possible words. Students must link graphemes to phonemes and analyze written letter structures within possible words, as they discover the next word. Another benefit is vocabulary. The clues require students to think about different words that are described in the clue. Students must retrieve possible words from their lexicon. Student collaborations about possible words usually help students to retrieve the necessary words. These conversations also help to link other possible words to words of similar meaning. Students also benefit from learning the meaning of words that are unfamiliar to them. The conversations grow, broaden and deepen student lexicon. This growth assists in student comprehension of both oral and written communication. This growth also strengthens student ability to write more complex sentences.
Many students will be frustrated until they understand how to complete the puzzle. Modeling or completing the process of the solving the ladder puzzle together a few times usually creates a student interest of completing the task independently or in collaboration. Matching student ability with the right grade level curriculum will also decrease student helplessness of solving the mystery. I usually use them as a whole class exercise. Students are allowed to collaborate and we usually go over the puzzle, so that every student feels included. When a student asks, I will give clues – leading questions or statements – that might help them to accurately solve the current clue.
Rasinski’s Word Ladders may still be used as a game. Students are usually motivated to solve the clues within each ladder to complete the puzzle. Many students like the competition of seeing who can solve the puzzle first. The puzzles may be a hard challenge for struggling students, when given as a whole class assignment. Allowing student collaboration usually eases the frustration. Some of that will depend how the puzzle(s) are used.
Teachers use Rasinski’s form of the puzzle to strengthen student spelling, written comprehension, vocabulary knowledge, oral language and or motivation to participate in literacy activities. These puzzles might be used in the regular class at grade-level to increase student knowledge of the previously noted. These puzzles might also be used as an intervention for student who are struggling with vocabulary knowledge or the other mentioned benefits.
