SC.4.P.12.1 Recognize that an object in motion always changes its position and may change its direction.
SC.4.P.12.2 Investigate and describe that the speed of an object is determined by the distance it travels in a unit of time and that objects can move at different speeds.
MAFS.4.NF.2.4 Apply and extend previous understandings of multiplication to multiply a fraction by a whole number
Solve word problems involving multiplication of a fraction by a whole number, e.g. by using visual
fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?

Students will:
•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 set amount of time using tools and technology.
•investigate and compare the speeds of different objects by measuring the amount of time it takes each object to travel a set amount of distance using tools and technology.
•display obtained speeds in chart, table, and graph format.
decompose a fraction into unit fractions (i.e., fractions with a numerator of one) and record the conclusion with a multiplication equation
solve word problems that involve multiplying a fraction by a whole number using visual models and equations. E.g., If each person at a party eats 3/8 of a pound of roast beef, and there are 5 people at the party, how many pounds of roast
beef are needed?
