|Unit of Instruction||Add/Subtract Fractions; Energy of Motion|
– Understand Addition and Subtraction of Fractions
SCIENCE: SC.4. P.12.1
– Recognize that an object in motion always changes its position and may change its direction.
|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.
