This kit comes with 148 rods, a self sorting tray, 50 activity cards, a wall poster, and an 80-page teacher's manual. Beginning with some early games, the concept activity cards include patterning, set theory, a step-by-step introduction to basic operations and fractions using the rods, as well as more advanced topics. You may want to use these each year with your children, going as far into the activities as their abilities allow. Everything you need to get started with Cuisenaire rods is right in this box!
