Greater Than, Less Than & Equal

I like this idea from CScope to give kids both an interactive and visual model of greater than, less than and equal to. This is normally a difficult concept; however this year, my students refer back to our pouring the liquid in the two cups pictured back and forth comparing the water levels. We then worked together to make the posters so we would have a visual to refer to for the rest of the year. The colored water has long since evaporated from the cups (which was another discussion altogether), but the students look at the pictures all the time!
