Embedded Files
Topic Title(s):
Count Numbers to 20
Prepared Graduates:
MP2. Reason abstractly and quantitatively.
MP3. Construct viable arguments and critique the reasoning of others.
MP7. Look for and make use of structure.
MP8. Look for and express regularity in repeated reasoning.
Standard(s):
1. Number and Quantity
The highlighted evidence outcomes are the priority for all students, serving as the essential concepts and skills. It is recommended that the remaining evidence outcomes listed be addressed as time allows, representing the full breadth of the curriculum.
Students Can (Evidence Outcomes):
K.CC.A. Counting & Cardinality: Use number names and the count sequence.
Write numbers from 0 to 20. Represent a number of objects with a written numeral 0–20 (with 0 representing a count of no objects). (CCSS: K.CC.A.3)
K.CC.B. Counting & Cardinality: Count to determine the number of objects.
Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects. (CCSS: K.CC.B.5)
Recognize that the number sequence from 1 to 9 repeats between the decade numbers, except in the spoken numbers between 10 and 20. (MP7)
Explain how the number reached when counting on is a relationship between the quantity started from and the quantity added. (MP3)
Make counting efficient by following rows, columns, or other patterns in a group of arranged objects. (MP7)
Inquiry Questions
When might you want to start counting from a number other than one?
What number can we use to show we have nothing to count?
Coherence Connections
This expectation represents major work of the grade.
In preschool, students understand that number words have a sequence and that the words are separate (not “onetwothree”).
In kindergarten, this expectation is key to several progressions of learning: (a) from saying the counting words to counting out objects, (b) from counting to counting on, and (c) from spoken number words to written base-ten numerals to base-ten system understanding.
In Grade 1, students extend the counting sequence to 120.
In Grade 1, students use their understanding of counting and cardinality to add and subtract within 20.
