Differentiation is valuable, essential and necessary, but can make some pupils feel a little self conscious because they either have a set of words that are seen to be “easier” than others, or another child can feel a little awkward because their list is “harder”. (Yes. That can happen).
Without realising it, we might restrict or limit one group or another. Here is a quick suggestion you might want to try:
Give everybody all of the spellings for that week. Do it in a Wordle. For each group, copy and paste their vocabulary in more frequently, (try 2 or 3 times).
Everybody gets all of the words, but… those who you might have defined as lower ability, could surprise you, and have a go at words that aren’t in their list.
For the top group, the other vocabulary is there to reinforce and revise spellings they might have forgotten.
On different levels, you have subliminal learning without restricting or insisting.
Something to think about, if only because the word lists look more attractive.
