Q3W2 (2/1 – 2/5)
Weekly-Assignments-February 1- February 5
|Unit of Instruction||Add/Subtract Fractions- Energy & Motion|
– 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.
– Add and subtract mixed numbers with like denominators e.g. by replacing each mixed number with an equivalent
fraction, and/or by using properties of operations and the relationship between addition and subtraction.
– Solve word problems involving the addition and subtraction of fractions referring to the same whole and having like

-Investigate and explain that sound is produced by vibrating objects and that pitch depends on how fast or slow the object vibrates.
-Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.
|Learning Targets and Learning Criteria|
The student will:
-Demonstrate with concrete and visual models 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.
-Decompose a mixed number into a sum of fractions equal to 1 and a fraction less than 1 to find an equivalent fraction to replace the mixed number in an addition or subtraction situation.
-Find equivalent sums or differences by converting fractions greater than 1 to mixed numbers by decomposing the fraction into a sum of fractions equal to 1 and fractions less than 1.
-Add and subtract mixed numbers with like denominators using equivalent fractions, and/or by using properties of operations and the relationship between addition and subtraction.
-Solve word problems involving addition and subtraction of fractions and mixed numbers with like denominators using visual fraction models and/or equations.
• describe the requirements/components necessary for sound to be produced.
• investigate the production of sound (e.g., tuning forks, hollow tubes, vocal cords, or water bottles filled with different amounts of water).
• explain that sound is produced by vibrating objects.
• investigate variations in pitch (e.g., water bottle liquids, rulers, straws, stretched rubber bands).
• explain that pitch depends on the speed (fast and slow) an object vibrates and the measurements (size and length) of the object.
• 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, and absorbs.
