Manipulatives List: Grade 2
		Following are the manipulatives for Grade Two. There are several categories of manipulatives listed here: Manufactured Manipulatives: a list of each of the manipulatives needed to implement fully the Math Trailblazers curriculum. Many of these manipulatives may be available already in your classroom or school.
		Manipulatives which you need can be purchased: in kit form from Kendall/Hunt Publishing Company; in a kit configuration which allows sharing between classrooms from Kendall/Hunt; or as individual items from your manipulatives supplier.
