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.12.1 SC.4.P.12.2
-Recognize that an object in motion always changes its position and may change its direction.
-Investigate and describe that the speed of an object is determined by the distance it travels in a unit of time and that objects can move at different speeds.

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 an object’s position and motion in space.

– explain that motion is a change of an object’s position.

– demonstrate that moving objects always change position.

– demonstrate that moving objects may change direction.

– explain that the speed of an object is determined by the distance it travels within a unit of time.

– investigate and compare the speeds of different objects by measuring the distance each object travels during a
set amount of time using tools and technology.

– investigate and compare the speeds of different objects by measuring the amount of time it takes each object
to travel a set amount of distance using tools and technology.

– display obtained speeds in chart, table, and graph format.
