Are you teaching your students about the colour orange. I have put together 30 high quality photos were the main colour in the image is orange. These make a great prompt for discussions about where you can see orange around you.
You could look at it directly as a presentation and discuss the different orange scenes being shown.
You could print off and laminate the photos to make an interesting, eye-catching display about where we see orange in the world.
The students could also take the laminated photos and sort them into different sorts of orange. The students can then discuss how they decided on each type of orange.
The photos could also be used as prompts for creative writing.
