Unit of Instruction | Decomposing and Composing Fractions for Addition and Subtraction also Understanding Fraction Equivalence and Comparison/Magnets/Natives of Florida |

Standard(s) Taught | |
---|---|

- Understand a fraction with a > 1 as a sum of fractions
- Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Examples: ;
- 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.
Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.
- Compare Native American tribes in Florida.

Learning Targets and Learning Criteria | |

- 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.
- 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., of a small pizza is not the same size as of a large pizza).
- Compare two fractions with different numerators and different denominators by:
- Using benchmark fractions (e.g., is close to and is close to 0, therefore > .
- 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 the comparisons.
- 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.
- Identify Florida’s different Native American tribes.
- Summarize the lifestyles of different Florida tribes.
