Topic Title(s):
Compose and Decompose Numbers 11 to 19
Prepared Graduates:
MP6. Attend to precision.
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.NBT.A. Number & Operations in Base Ten: Work with numbers 11-19 to gain foundations for place value.
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones. (CCSS: K.NBT.A.1)
Be precise in drawings, diagrams, and numerical recordings about objects or symbols that represent ones and objects or symbols that represent tens. (MP6)
See the structure of a number as composed of its base-ten units. (MP7)
Repeat the reasoning afforded by the uniformity of the base-ten system, where 10 copies compose 1 base-ten unit of the next highest value. (MP8)
Inquiry Questions
Can you show the number 13 as ten ones and some more ones? How many more ones than tens are there?
In the number 11, what makes the “1” on the left different from the “1” on the right? Could you show this with objects or a diagram?
What would a number called “ten four” look like? What word do we usually say for this number?
Why might someone call the number 17 “ten seven?”
Coherence Connections
This expectation represents major work of the grade.
In preschool, students develop conceptions of addition and subtraction when adding to and taking away from small collections of objects.
In kindergarten, this expectation is part of a progression from comparison by spoken number words to written base-ten numerals to base-ten system understanding.
In Grade 1, students build an understanding of ten and place value with two-digit numbers.
