Cluster B – Understand Place Value
1.NBT.B.2 / 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). / Lessons: 7-1, 7-3, 7-5, 7-6, 8-1, 8-2, 8-3, 8-4, 8-5, 8-6

Cluster C – Use Place Value Understandings and Properties of Operations to Add and Subtract
1.NBT.C.4 / 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. / Lessons: 9-2, 10-1, 10-2, 10-3, 10-4, 10-5, 10-6
