Unit 1 Extending the Counting Sequence Math
Grade 1 


Unit Length and Description: Length: 3
weeks Description: This unit focuses on the
numbers 0 to 120. Students will orally
count, write, and read numbers within this range. They will represent a number of objects
with a written numeral. Students will
be introduced to the idea of making tens in order to count larger groups of
items. The term digit will be introduced. 

Standards: Operations and Algebraic Thinking 1. OA.5  Relate counting to
addition and subtraction (e.g., by counting on 2 to add 2). Number and Operations in Base Ten 1.
NBT.1  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. 1. NBT.2  Understand that the two digits of a
twodigit number represent amounts of tens and
ones. Understand the following as
special cases:
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). Standards for
Mathematical Practice (MP) MP.1  Make sense and persevere
in solving problems MP.2  Reason abstractly and
quantitatively MP.7  Look for and make use of
structure MP.8  Look for and express
regularity in repeated reasoning CCSS for ELA Content Reading Standards for Informational
Text RI.1.10
 With prompting and support, read informational texts appropriately complex
for grade 1. Writing W.1.8
With guidance and support from adults, recall information from experiences
or gather information from provided sources to answer a question Speaking and Listening SL.1.1
 Participate in collaborative conversation with diverse partners about grade 1 topics and texts with peers and adults in small and larger
groups. c. Ask questions to
clear up any confusion about the topics and texts under discussion. Standards: Instructional Outcomes 1. OA.5: Relate counting to addition and subtraction
(e.g., by counting on 2 to add 2).
1. NBT.1: 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.
1. NBT.2: Understand
that the two digits of a twodigit number represent amounts of tens and ones. Understand the following as
special cases:
·
I
can represent numbers 20 to 90 as tens and zero ones. 

Enduring Understandings: Students
will be able to extend the counting sequence to 120 starting at any number
less than 120. Students will count by 1s, 5s, and 10s. Students will relate counting up to
addition and counting back to subtraction. Students will read and write
numbers in the range of 1 120 and build number sense by developing an
understanding of the order of the counting numbers. Students
will be able to represent a number of objects with a written numeral. Students will understand that the two
digits of a twodigit number represent amounts of tens and ones. 
Essential Questions: 1.
How do we show that numbers work
together? 2.
How can we show and explain our
thinking? 3.
How does understanding numbers help
me?
