Number rods and Sandpaper numerals

Another aspect of Montessori education I really like is math.  All lessons are "hands on" versus worksheets and the materials are really beautiful and practically beg to be touched and used.  These are our number rods and sandpaper numerals.  Wyatt is already counting past 10 and recognizes numerals 0-9 easily.  This next exercise was pretty easy for him but he still enjoyed it.  He has had earlier lessons in just the number rods (making the "staircase", counting each one, putting them in order 1-10) but today we added something new. 

First we reviewed the sandpaper numerals and practiced tracing each one.  Then he laid out the number rods on his mats.  Next he had to count each rod and match the corresponding numeral to the correct rod.  When he was finished he had me come over and he counted each one, proudly showing me that he matched them all correctly.
