Determine the unknown whole number in an
addition or subtraction equation relating three
Identifying Missing
Numbers in Equations 1.OA.8 whole numbers. For example, determine the 60-67
unknown number that makes the equation true in
each of the equations 8 +? = 11, 5 = – 3, 6 + 6 = .
Read, Write, and Count to 120, starting at any number less than 120.
Count Numbers 1.NBT.1 In this range, read and write numerals and represent 68-75
to 120 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:
Tens and Ones 1.NBT.2.a a. 10 can be thought of as a bundle of ten ones — called 76-83
in Two-digit Numbers 1.NBT.2.c a “ten.” 84-91
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
Comparing Numbers 1.NBT.3 of the tens and ones digits, recording the results of 92-99
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
Two-Digit
Addition 1.NBT.4 relationship between addition and subtraction; 100-107
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.
Calculating Given a two-digit number, mentally find 10 more or
10 More 1.NBT.5 10 less than the number, without having to count; 108-115
and 10 Less 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
Two-Digit Subtraction 1.NBT.6 and strategies based on place value, properties 116-123
of operations, and/or the relationship between
addition and subtraction; relate the strategy to a
written method and explain the reasoning used.
Comparing and 1.MD.1 Order three objects by length; compare the lengths 124-131
Ordering Length of two objects indirectly by using a third object.
