• Model and express a fraction, including mixed numbers and fractions greater than one, with the denominator 10 as an equivalent fraction with the denominator 100.
• Use decimal notation to represent fractions with denominators of 10 or 100, including mixed numbers and fractions greater than 1.  Use fractional notation with denominators of 10 or 100 to represent decimals.
• Plot, order, and compare decimals up to the hundredths.
• Solve one and two-step addition and subtraction real-world problems involving money using decimal notation.
• Explore the addition of a fraction with a denominator of 10 to a fraction with a denominator of 100 using equivalent fractions.
• Identify the number that is one-tenth more, one-tenth less, one-hundredth more, and one-hundredth less than a given number.
• Explore the addition and subtraction of multi-digit numbers with decimals to the hundredths.

SCIENCE:   SC.4. E. 6.3

• Recognize that humans need resources found on Earth, and that these resources are either renewable or nonrenewable.
Learning Targets and Learning Criteria

The students will:

• Identify models of tenths and hundredths.
• Write tenths and hundredths as equivalent fractions and decimals.
• Explain how to compare two decimals.
• Apply understanding of decimals to solve money problems.

•    Define resources as anything from the environment that meets our needs and wants.
•    Provide examples of renewable resources (e.g., water, wind, solar, trees).
•    Provide examples of nonrenewable resources (rocks, minerals, soil, and fossil fuels such as coal, oil, natural gas).
•    Identify renewable and nonrenewable resources found on Earth that humans need and how they are used.
•    Distinguish between renewable and nonrenewable resources found on Earth.
•    Explain that nonrenewable resources exist in a fixed quantity on Earth and may be used up.
