Standard(s) Taught

MATH:    MAFS.4.NF.1.1       MAFS.4.NF.1.2

• Explain why a fraction a/b is equivalent to a fraction  n X a/ n X b by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
• 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 the symbols  >, =, or < and justify the conclusions.

SCIENCE:    SC.4.P.8.1    SC.4.P.8.4     SC.4.P.8.2     SC.4.P.8.3     SC.4.P.9.1

• Measure and compare objects and materials based on their physical properties including: mass, shape, volume, color, hardness, texture, odor, taste, and attraction to magnets.
• Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.
• Identify properties and common uses of water in each of its states.
• 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.
• Identify some familiar changes in materials that result in other materials with different characteristics, such as decaying animal or plant matter, burning, rusting, and cooking.

Social Studies

• SS.4.A.3.1 Identify explorers who came to Florida and the motivations for their
expeditions
• SS.4.A.3.2 Describe causes and effects of European colonization on the Native
American tribes of Florida.

Learning Targets and Learning Criteria

Math

The student will:

• Explain using visual fraction models, how and why fractions can be equivalent even though the number and size of the parts are not the same.
• Recognize and generate equivalent fractions by partitioning number lines, rectangles, squares, and circles.
• Recognize and generate equivalent fractions by using the conceptual understanding of the relationship between altering the size of the parts and the resulting effect on the number of parts.
• 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).
• Compare two fractions with different numerators and different denominators by:
1. using benchmark fractions: 5/8 is close to 1/2 and 1/10 is close to 0, therefore 5/8 > 1/10
2. reasoning about their size or location on a number line
3. using visual models to create fractions with common numerators or common denominators
• Record the results of comparisons with the symbols >, <, and =
• Justify the conclusions of comparisons.

Science

The students will:

• Compare objects based on observable and measurable physical properties (shape, color, hardness, texture, odor, taste, attraction to magnets, mass, volume, and temperature.)
• Investigate and explain that all matter has the following measurable properties: volume-takes up space, and mass- weight.
• Record and compare the mass and volume of solid and liquid matter using metric units.
• Record and compare the volume of regular and irregular shaped solids using the water displacement method.
• Display data appropriately in charts, tables, and graphs.
• Compare measurement data with other lab groups checking for accuracy.
• Explain any differences that may have occurred across groups.
• Investigate and classify objects that are attracted to magnets (paper clips, iron filings, scissors) and those that are not (bottle, penny, copper wire, eraser, foil, nickel, steel).
• Investigate that all magnets, regardless of shape, have a north pole N and a south pole S although they may not be marked.
• Investigate the presence of a magnetic field with different shaped magnets.
• Describe the effects of the magnetic field of different shaped magnets using iron filings.
• Investigate how magnets attract and repel other magnets based on the presence of a magnetic field.
• Demonstrate that the mass of a whole object is always equal to the sum of its parts.
• Explore the Law of Conservation of Mass (whole=sum of its parts) to obtain the mass of various objects using tools and technology.
• Identify familiar physical and chemical changes in matter.
• Describe observable signs that a chemical change may exhibit (smell, color, heat, fizzing, substance given off.)

Social Studies

The students will:

• Research a famous explorer significant to Florida. Identify reasons for their expeditions, interaction with Native Americans, and any conflicts they had.
