I was trying to indicate that the word bisector is telling us we need the midpoint. But yes, I am aware that this doesn't help with colour blindness. Obviously in class I also explain and use gestures too.

I normally move to that post 16, but I find that they understand y=mx+c better for the link to the graph when younger.

I love all the resources from @draustinmaths, they are always well thought out.
If you need more of these, you can create this type of activity with randomly generated questions on many topics on my site. Choose 'Codebreaker' as Activity Type.

Of particular interest might be the frequency analysis tool that can be used to break and simple substitution cipher.

Frequency Analysis: Breaking the Code

It is great. I have done it on and off with students for 10+ years. You can either set them off and they will sort it themselves (older students) or do a weekly activity to support them. KS3 will need a bit of support, but might catch the bug and do it every year.
