I used this blank family tree to teach "family members" vocabulary to my 2nd graders. It was easier for me to create a pretend family to use an example. I had previously tried to have students create their own family trees and it became too complicated and difficult.
I created this pretend family and also made up a little story about them as I went along. I introduced the vocabulary as we drew each family member and even gave them names. I had students choose a color to represent the males and a color to represent the females and they underlined each vocabulary word with the corresponding color.
Using a third color, the students underlined the last letter of each vocabulary word (minus mamá y papá) three times. I asked if the students were able to draw a conclusion about the words that ended with "o" versus the words that ended with "a." Ultimately, I wanted to illustrate masculine and feminine properties without getting too complex.
I did this step-by-step using my document camera since it was an introductory lesson. This page can be used in various ways, so make it your own!
