I use this worksheet in centers to practice special words like tricky words (or sight words). They chose a word from a list that the teacher writes in the board and write it in the big rectangle on top of the page. Then they write the same word again with their pencil, crayons, color pencils and crayons.

Another way to practise past tense. 
I use this memory game to teach past regular.

I found it on Pinterest. It belongs to https://masandpas.com/fun-with-phonics-magnetic-fishing-game/
This fishing game is something like "La pesca milagrosa". The students need to fish the pictures with a wooden (or pencil) rod, a magnet and a paperclip. I did it with synonyms/antonyms, but you can adapt it to phonics, proper/common nouns, etc,
I added some fish shapes that I downloaded from https://onelittleproject.com/fish-outlines/

I use this WS as a center. Students play in pairs with dice, roll it, read a word in the column that corresponds to the number that appeared in the dice and color it. The first one completing a column wins, or also the student that read and color more words.
