|Subject Area||Math and Science|
|Unit of Instruction||Add and Subtract Fractions/Matter and Energy|
– Understand a fraction a/b with a>1 as a sum of fractions 1/b.
– 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
-Investigate and describe how energy can create change in matter (e.g., heat energy can melt ice, moving water can
-Explain the relationship between energy and motion.
