There is a quiz shoe in Britain called “Countdown” where the contensants have to make words out of 9 letters.
I use this same idea in my class as a warmer, or as an acitivity to fill the last 10 minutes of a lesson.
Choose a 9 letter word: eg, policeman, birthdays, traveller, spiderweb, superhero, tracksuit. Then draw a 3×3 grid on the board and mix the letters up.
In pairs, give the students 5 minutes to find as many words as possible (min 3 letters). Tell them there is a 9 letter word which is worth extra points.
When the time is up, get the students to count their words and see which team has the most, then brainstorm the words on the board and help them find the 9 letter word
