Unit 1 Place
Value and Decimal Fractions and Metric Measurement Conversions Grade 5 

Description:
Students
understand patterns in the base ten system as they work with multidigit
whole numbers and decimals to the thousandths place. They will understand that in multidigit
numbers, a digit in one place represents 10 times what it represents in the
place to its right and of what it
represents in the place to its left. Students
will use whole number exponents to denote powers of 10. Students will also explain patterns in the
placement of the decimal point when a decimal is multiplied or divided by a
power of ten. Students read, write, and compare decimals to thousandths. Students will extend their understanding
with using decimal notation for fractions with denominators of 10 and 100 to 1000. They read decimals using fractional
language and write decimals in fractional form, as well as in expanded
notation. Students compare two
decimals to the thousandths place using >, =, and <. Students will use place value understanding
to round decimals to any place. Students will apply their place value
understandings to problem solving with metric conversions.

Enduring
Understandings: ·
Understanding
the multiplicative patterns of the base ten system helps me compose and
decompose numbers. ·
It is
important to understand that a digit represents 10 times the value of what it
represents in the place to its right, and 1/10 of what it represents in the
place to its left. ·
Using
exponents involving powers of 10, helps me solve problems with metric
conversion. ·
Understanding
place value helps me read, write, compare and round decimals and perform
mathematical operations. 
Essential
Questions: ·
What is the
relationship between the number of factors of 10 and the shift of the
position of the digits on a place value chart? ·
