Quarter Three: Week #26th February 20th-23rd Lesson Plans (Math/Science/S. Studies Homeroom Only)

Teacher Michael Lee Math/Science/S. Studies 4th Grade Week #26th February 20th-23rd Lesson Plans Angle measurement /Motion of Objects
Standard(s) Taught

Math: 4.MD.3.5, 4.MD.3.6, 4.G.1.1 (not parallel, perpendicular, or 2-D figures)

1.      Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement.

a. An angle is measured with reference to a circle with its center at the common

endpoint of the rays, by considering the fraction of the circular arc between the

points where the two rays intersect the circle. An angle that turns through 1360

of a circle is called a “one-degree angle,” and can be used to measure angles.

b. An angle that turns through n one-degree angles is said to have an angle measure

of n degrees.

2.      Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

3.      Use a protractor to sketch an angle given a specific measurement.

Science: SC.4.P.12.1, SC.4.P.12.2

 1.    Recognize that an object in motion always changes its position and may change its direction. 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.
Learning Targets and Learning Criteria

Math:

1. Recognize an angle as a geometric shape that is formed when two rays share a common endpoint.

1. Explain the relationship between a circle and the number of degrees in an angle (i.e., an angle is measured in reference to a circle—its center is the endpoint for each of the rays that make up the angle).
2. Explain an angle as a series of “one-degree turns” and the total number of “one-degree turns” is the measure of the angle in degrees.

E.g., A water sprinkler rotates one-degree at each interval. If the sprinkler rotates a total of 100 one-degree turns, what is the measure of the sprinkler’s rotation in degrees?

1. Explain that since it takes 360 “one-degree turns” to rotate through a circle, 1/360 of a circle is a “one-degree angle”.

1. Measure an angle to the nearest whole number degrees using a protractor.

1. Use a protractor to sketch an angle given a specific measurement.

Science:

1. Describe an object’s position and motion in space.
2. Explain that motion is a change of an object’s position.
3. Demonstrate that moving objects always change position.
4. Demonstrate that moving objects may change direction.
5. Explain that the speed of an object is determined by the distance it travels within a unit of time.
6. 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.
7. 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.
8. Display obtained speeds in chart, table and graph format.
