Why teach spelling rules?

There’s been some conversation recently about structured literacy programs that don’t teach the most important spelling rules (generalisations) to students. This leads to the broader conversation about whether spelling rules are an unnecessary distraction, and whether just teaching ‘more common’ and ‘less common’ spelling patterns is the way to go.
In this post, I discuss why at Playberry Laser T1-2 and Playberry T3, we place a strong emphasis on teaching spelling rules, and why failing to teach them dooms too many students to ‘safe’ spelling choices when it comes to writing.
