Student can describe
that 10 can be thought of as a bundle of ten ones
called a "ten"� 50% or less of the time. Can tell
that the number from 11 to 19 are composed of a ten
and one, two three, four, five, six, seven, eight, or
nine ones 50% or less of the time. Students can tell
that the numbers 10, 20, 30, 40, 50, 60, 70 , 80 ,90,
refer to one, two, three, four, five, six, seven, eight,
or nine tens and zero ones 50% or less of the time.
Student can Compare two two-digit numbers based on meanings
of the tens and ones digits, recording the results of
comparisons with the symbols <, >, = 50% or less of
the time.

Given a two-digit number
mentally find 10 more or 10 less than the number without
having to count, explain the reasoning used 50 % or
less of the time. Subtract multiples of 10 in the range
10 90 using concrete models or drawings and strategies
based on place value, properties of operations, and/or
the relationship between addition and subtraction and
explain the reasoning used 50% or less of the time.
Add within 100, including adding a two digit number
and a one-digit number, and adding a two-digit number
and a multiple of 10, using concrete models or drawings
and strategies based on place value, properties of operations
used 50% or less of the time.
