Teacher Brooke Brackney Math/Science/Social Studies 4 12 Decomposing and Composing Fractions for Addition and Subtraction also Understanding Fraction Equivalence and Comparison/Magnets/Florida Explorers
Standard(s) Taught

Math

MAFS.4.NF.2.3

Understand a fraction with a > 1 as a sum of fractions

MAFS.4.NF.1.1

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

Science

SC.4.P.8.4

Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.

Social Studies

SS.4.A.3.1

Identify explorers who came to Florida and the motivations for their expeditions

Learning Targets and Learning Criteria

Math

Students will:

Explain, using visual representation, 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 using visual models.

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 /2of 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 ).

Reasoning about their size or location on a number line.

Using visual models to create fractions with common numerators or common denominators.

Record the results of comparisons with the symbols <, > or =. • justify the conclusions of comparisons

Science

Students will:

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.

Social Studies

Students will be able to:

Identify explorers who landed in Florida

Explain why explorers came to Florida and the outcomes of their expeditions
