Unit 5 Numbers 10 20 and Counting to 100 Kindergarten Math 


Description:
Students explore
numbers 1020. They apply their skill
with and understanding of numbers within 10 to teen numbers, which are
decomposed as 10 ones and some ones.
For example, 12 is 2 more than 10.
The number 10 is special and is the anchor that will eventually become
the ten unit in the place value system if future grades. 

Standards: 





Enduring Understandings: ·
Students will count to 100 by ones and
tens. They will count objects to 20 and represent that number of objects
with a written numeral from 120. ·
Students will use comparative vocabulary to
describe items in two sets between 120. ·
Students will compare two objects with a
measurable attribute in common to see which object has more of/less of the
attribute and describe the difference. They will be introduced to solving
addition and subtraction word problems and to adding and subtracting within
10 using objects fingers and/or drawings. ·
Students will decompose numbers up to 20 into
partners in multiple ways (e.g. 12 = 10 + 2 and 12 = 7 + 5). They will
begin to find a number that makes 20 when given any number from 1 19. ·
Students will gain an understanding of place
value by composing and decomposing teen numbers in addition sentences. ·
Students
will record each composition or decomposition using a drawing or equation
(e.g., 18 is one ten and eight ones, 18 = 1 ten + 8 ones, 18 = 10 + 8).
