This video illustrates the use of scaffolding with manipulatives to teach students to group objects by tens with counting by ones.  When students practice counting numbers greater than 10 with manipulatives, they learn to recognize the patterns in place value and they begin to think about sets of 10 objects as one unit. Students develop fluency in counting by ones, and then counting by groups of 10 and ones. Once that skills is mastered they are ready to practice opportunities to count by tens and ones to determine cardinality (i.e., the total amount of the set).
