We’ve already learned quite a few of opposites before we got to this lesson. BIG and small, hot and cold. I introduce opposites without ever translating it or defining it. I just give examples of opposites and let the child, through context, discover the meaning on their own, naturally. Each of my students, no matter the age, quickly pick up on the meaning.
Opposites naturally are game friendly. I show one word and they must do the opposite. If I point up, they point down. If I show cold by shivering, they show hot by wiping their brow.
Memory is great for opposites. They can search for the same or the opposite.
Also we did the drawing game. I draw something and say they must draw either Same, Different, or Opposite.
My student drew the picture on the left and my version of opposite is on the right. She insisted the tree looking thing was an umbrella. I don’t know what the opposite of umbrella is!
This is my student’s (age 5) answer of opposite of a red cat up sitting on a book shelf. A green dog down not on a book shelf.
