I met with a small group to "test out" this lesson idea. The children in the pictures were two students who really grasped the concept so they are going to help me teach the rest of the class the next time I am at their school!
First, we used Scratch to program a Christmas tree sprite (character) that we added to a holiday background to dance when synonyms were selected and to turn upside down when antonyms were selected. After I prompted the students to work with a partner to experiment with their code. This was a hard task for 2nd graders but they did it with very little assistance!
Before we started decorating the tree, the students needed to finish their Scratch program by recording their voices saying "Synonyms" and "Antonyms".
Next, I explained the concept of a MaKey-MaKey (click HERE to take you to a guest post I wrote for Free Technology for Teachers this past year about this tool) and each student wrapped a Christmas ball ornament with tinfoil. Since most Christmas ornaments/balls are made of glass, they aren't conductors so we had to get creative by wrapping them with tinfoil :)
Then the students used sticky labels to write pairs of words that represented synonyms and antonyms.
Way to go, 2nd graders!
