It is easy to get stuck in a rut with vocabulary and repetition activities but this is a new one. It is based on students trying to cross an obstacle course.
Put 9 new items of vocabulary in a 3×3 grid on your projector screen. Students draw 9 dots on a mini- whiteboard. Then draw 5 consecutive lines like an unlock code on an android phone (see work of art below). Their partner tries to crack their pin-code by saying the vocabulary. The student with the code can only respond with “correct” or “incorrect”. They then swap around.
My thanks to everydaymfl.com for this idea.
