# Q3W1 (1/4 – 1/7) Teacher Kathleen Manning Math and Science 4 1 Fraction Equivalence and Ordering/Energy and Motion
Standard(s) Taught

MATH: MAFS.4.NF.1.1

– 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.

MAFS.4.NF.1.2

– 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 results of comparisons with symbols: >, <, or = and justify the conclusions by using a visual fraction model.

SCIENCE: SC.4.P.10.1

– Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.

Learning Targets and Learning Criteria

Students 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 parts.

– Explain that fractions can only be compared when they refer to the same sized whole.

– Compare two fractions with different numerators and different denominators by: using benchmark fractions, reasoning about their size or location on a number line, or 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.

– Review how light travels in a straight path until interrupted by an object.

– Review how light passes through other objects (transparent, translucent, opaque).

– Review how light reflects, bends, absorbs.

– Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion (mechanical energy).

– Identify examples of these energy forms in their life and in the natural world.

– Compare and contrast these types of energy.
