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. |
