Manipulatives are blocks, algebra tiles, cubes, rods, fraction pieces, and pattern blocks that are used in mathematics classes for students to make meaning of abstract ideas and symbols. (Manches, Claire, Benford, 2009)
Concrete Vs. Virtual Manipulatives Concrete Manipulatives are physical objects students can manipulate to explore and develop an understanding of mathematical concepts. Virtual Manipulatives are computer-based simulations of physical manipulatives that can be accessed through the internet or computer software.
