Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1 2 . Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model. MAFS.4.NF.1.2
Explore the Law of Conservation of Mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts. SC.4.P.8.3
Identify properties and common uses of water in each of its states. SC.4.P.8.2
Compare Native American tribes in Florida. SS.4.A.2.1
• explain that fractions can only be compared when they refer to the same sized whole (e.g., 1 2 of a small pizza is not the same size as 1 2 of a large pizza). NOTE: Denominators limited to 2, 3, 4, 5, 6, 8, 10, 12, 100.
• compare two fractions with different numerators and different denominators by: o using benchmark fractions (e.g., 5 8 is close to 1 2 and 1 10 is close to 0, therefore 5 8 > 1 10 .
o reasoning about their size or location on a number line.
o multiplying by a fraction equivalent to 1 to create common numerators.
o multiplying by a fraction equivalent to 1 to create common denominators.
• record the results of comparisons with the symbols <, > or =.
• justify the conclusions of comparisons. NOTE: Fractions may be greater than 1 (e.g., 6 5 ). Students need to be able to generate equivalent fractions, but will NOT use the language, “least common denominator”
• explore the Law of Conservation of Mass (whole = sum of its parts) to obtain the mass of various objects using tools and technology.
• demonstrate that the mass of a whole object is always equal to the sum of its parts.
• investigate and describe properties of water in all three states.
• identify common uses of water in all three states.
• explain the importance of water to life on Earth.
• identify Florida’s different Native American tribes. Examples may include, but are not limited to, Apalachee, Calusa, Tequesta, Timucua, and Tocobaga.
• summarize the lifestyles of different Florida tribes.
