If your students are hikers and have had previous experience eating trail mix snacks, then reading a book about hiking for engagement could lead to a discussion about mixtures. But unless you know this about the class, an engagement more directly about a mixture could be more effective. Also—does your school allow food, other than student lunches, to be used in teaching?
How will you elicit students’ prior knowledge?
What mixtures are common in your students’ everyday life? A loose change jar, breakfast cereal, or a bag of hair clips and ties?
If no student has allergies to nuts, students could observe and sort a spoonful of a bird seed mixture as you read a short book about birds such as Collard and Brickman’s book, Beaks!
The paper clip activity will build on the engagement by giving them the opportunity to see how a tool makes the process of separation much easier.
I look forward to Kathy Renfrew’s ideas and those of other student teachers and preservice teachers!
Best wishes, Peggy
