# Q3W1 (1/26 – 1/30)

Weekly-Assignments-January 26-January 29 Teacher Kathleen Manning Math and Science 4 1 Add and Subtract Fractions/Matter and Energy
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.
– 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
denominators.

SCIENCE: SC.4.P.10.2

– Investigate and describe that energy has the ability to cause motion or create change.

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.

-Investigate and describe how energy can cause motion (e.g., moving water can turn a water wheel to make
hydropower, wind can move sand across the beach or sail a model boat, solar energy can power a model car).

-Investigate and describe how energy can create change in matter (e.g., heat energy can melt ice, moving water can
make rocks smooth, light can keep food warm).

-Explain the relationship between energy and motion.
