# Q3W4 (1/24 – 1/28) Teacher Kathleen Manning Math/Science 4 4 Add/Subtract Fractions; Energy of Motion
Standard(s) Taught

MATH: MAFS.4.NF.2.3

– 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.
– 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.
