MATH:   MA.4.FR.1.1     MA.4.FR.1.2     MA.4.FR. 1.5     MA.4.FR. 2.2     MA.4.FR. 2.3     MA.4.FR. 2.6     MA.4.FR. 2.7

• 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.P.10.4

• Describe how moving water and air are sources of energy and can be used to move things.
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.

• Investigate and describe how energy can cause motion (e.g., moving water can turn a water wheel to make hydropower, wind can move sand across the beach or sail a model boat, solar energy can power a model car).
• Investigate and describe how energy can create change in matter (e.g., heat energy can melt ice, moving water can make rocks smooth, light can keep food warm).
• Explain the relationship between energy and motion.
