# Q2 W11 Oct. 22nd-Oct. 26th

Teacher Angela Mariner Math and Science 4 11 Adding and Subtracting Fractions/Magnets
Standard(s) Taught
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 size whole is joining parts of the wholes.

• demonstrate with concrete and visual models that subtracting fractions referring to the same size 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.
