# Quarter 2, Week 11: Oct. 22-26

Teacher Brooke Brackney Math/Science/Social Studies 4 11 Decomposing and Composing Fractions for Addition and Subtraction /Magnets/Florida Explorers
Standard(s) Taught

Math

MAFS.4.NF.2.3
Understand a fraction a/b with a > 1 as a sum of fractions 1/b
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.
Examples: 3/8= 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8

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:

Demonstrate with concrete and visual models (i.e., number lines, rectangles, squares, and circles) that adding fractions referring to the same sized whole is joining parts of the wholes.

Demonstrate with concrete and visual models that subtracting fractions referring to the same sized whole is separating parts of the wholes.

Decompose a fraction (less than or greater than 1) into a sum of fractions with the same denominator in more than one way using visual models.

Record the decomposition of a fraction by an equation and justify the decomposition.

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:

Identify explorers who landed in Florida

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