Simple inequalities in Venn diagrams

Students work in pairs to sort integers into a variety of Venn diagrams. The aim is to become familiar with the symbols for greater than (/and equal to), less than (/and equal to).
Options to use outside (with chalk and a flat floor) or inside (on paper).
Note the ‘deliberate mistake’ on the last Venn; the notation means there are no possible values in the red set. I’ve seen students attempt to represent two separate regions like this many times, so included it as a discussion point.
