In class, I wrote & read out the target words ie the caption/storyline on the board as well, and asked students to find the corresponding picute/caption. The captions were quite similar so required care. Compare "Tom is a monkey" to "Tim is a man". We pasted our agreed answers (quicker ones had to wait until every else was ready) into the appropriate frame. I deliberately do not have enough glue sticks etc to go around (at this age) because I want them to ask for things off each other & use 'sharing' language. A very good way to get 'Please' and 'Thank you' working!
The end result is in this audioboo; yes, they are mostly mimicking me I know, but this is the most they have ever 'read' in English, and they loved being able to 'do it'!
