Reviewing language from previous lessons is a good idea (spaced repetition being a buzzword in memory and learning). So maybe you want to revise some of yesterday's vocabulary or grammar at the start of the lesson as a warmer.
Back to the Board
I don't know any experienced teachers who haven't done this. Class in two teams. One student from each team sits at the front, with their back to the board. You write a word on the board behind them. Their team must define/act the word for them to guess. First team to guess wins a point. After a few words, swap students and let two others try. Warning: can get very loud.
There are lots of variations on this. The simplest is to write 15-20 words from previous lessons on the board. Class are standing in two teams, red team with red board pen, blue team with blue board pen. You define a word, the students with the pen run to the board to circle the word. The first team to get the word get a point. Then they hand the pen to another team member, and you define another word.
This is just an alternative way of presenting a define-the-words game. While the original online version of Wordle is no longer supported, there are others (e.g. Word Clouds). Anyway, the idea is that you type in the vocabulary you want to review. Change the font / colours or anything else you fancy to make it pretty. Then give a copy to groups of 3-4 students. Students take it in turns to choose a word and try to explain it - the others try to guess the word from the word cloud.
There are some more Wordle teaching ideas on my Wordle Activities page.
Jumble up words from your previous lesson, and get students to unscramble them. If you have time, put the letters on little squares of card, then put each anagram on a different table and get students to move around the room and solve each one (they should mix the letters up again when they've solved it) . I also use a PowerPoint version of this - anagrams PowerPoint slides which works well as a quiz game to review vocabulary.
