Knotwords helps kids practice and improve the following skills:

Working Memory: Recalling and retaining information in our minds while working. 

In order to complete the puzzle, the player needs to remember the spelling of the word they want to use while they are solving individual chunks of the puzzle. If they spell the word wrong, they will see that the incorrect answer is scribbled out in pink, meaning that they need to correct something before the puzzle can be completed. While the length of time the player takes to complete the puzzle is measured, there is no time limit to complete the puzzles, so players can take their time and practice their working memory skills without time pressures. 

Flexibility: Trying something new. 

In order to solve the puzzles in the game, the player needs to be able to use their flexibility skills to try new words. Sometimes a word will fit into a set of boxes but will still not be the correct answer to the puzzle. The player will see this when they complete other sections and run out of options for words to spell. The player then needs to use their flexibility skills and try new combinations of letters to spell different words or adjust one or two letters to create a new word. If the player is stuck they can always use a hint but these are limited so playing with the idea that you will need to adjust your letters is a good frame of mind to have.
