Tips for Encouraging Vocabulary Usage
Vocabulary Coordinate Plane - Create a Coordinate Plane out of paper and attach it to something in the classroom, like the pencil sharpener. Whenever students are in that spot, they have to use the vocabulary word “coordinate plane” in a sentence. Move the “Coordinate Plane” to different locations throughout the week, add sound effects if you’d like, and make it a fun sort of “search and find” vocabulary adventure!
Word Detective/Scavenger Hunt: Teacher will hide words around the room. Students will find a word and work with a partner to define the word, draw a picture and use it in a sentence.
Digging Deeper Graphic Organizer: Students will identify the key term, information about it, and a memory cue based on their own understanding of the vocabulary term. Write the term or key idea (K) in the left column, the information (I) that goes along with it in the center column, and draw a picture of the idea, a memory clue, (M) in the right column. The key idea may be a new vocabulary word, or a new concept. The information may be a definition or it may be a more technical explanation of the concept. The memory clue is a way for students to fully integrate the meaning of the key idea into their memories. By making a simple sketch that explains the key idea, students synthesize and interpret the new information, making it their own. Then, students can reference their drawings to easily remember new key ideas.
