Count to 120, starting at any number less than 120. In this range, read and write numerals and
represent a number of objects with a written numeral.
Understand that the two digits of a two-digit number represent amounts of tens and ones.
Understand the following as special cases:
a. 10 can be thought of as a bundle of ten ones—called a “ten.”
b. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven,
eight, or nine ones.
c. 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 0 ones).
Compare two two-digit numbers based on meanings of the tens and ones digits, recording the
results of comparisons with the symbols >, =, and <.
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, and/or the relationship between addition and subtraction; relate the
strategy to a written method and explain the reasoning used. Understand that in adding two-digit
numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a
ten.
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to
count; explain the reasoning used.
Subtract multiples of 10 in the range 10–90 from multiples of 10 in the range 10–90 (positive or
zero differences), using concrete models or drawings and strategies based on place value,
properties of operations, and/or the relationship between addition and subtraction; relate the
strategy to a written method and explain the reasoning used.

Mathematical Practices
By the end of this unit, students will be able to:
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
