SCIENCE: SC.4.P.12.1 SC.4.P.12.2
|Learning Targets and Learning Criteria|
The student will:
-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
– investigate and compare the speeds of different objects by measuring the amount of time it takes each object
– display obtained speeds in chart, table, and graph format.
