Numbered Heads Instructions
1. Form into the designated groups
2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.
3. Hand the paper to the instructor. It will be used for assessment and graded.
4. Begin reviewing/ learning the listed concepts. Make up sample questions related to the concept. Try and figure out what question the teacher will ask. Time is limited; so don’t waste it!
5. Once you understand the concepts make sure each group members also understand by assessing them. Do not ask yes or no assessment questions.
Good Assessment. “Sam, could you show me how to do number three on the list?”
Poor Assessment. “Do you guys all know it?”
6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a calculator. After they leave begin studying the next set of concepts for the next round.
7. After a short amount of time the person will then return to the group and their answer will be graded by the teacher and given to the entire group as a communal score.
8. The returning group member may be called again so they should receive extra instruction to help get caught up.
9. The scores are added at the end to determine winners. The top three groups receive extra points on the test.
1. definitions of vector and scalar
2. define each as vector or scalar---mass, time , distance, displacement, speed, velocity, volume, acceleration, temperature---Know why each is what it is.
3. diven size and direction of vector A and vector B be able to draw and identify
A + B A-B B-A -B - A
4. Given two perpendicular velocities , find the resultant velocity
5. Given three displacements, one east, one west and one south find the resultant
6. Be able to explain in words how to use sine and cosine and tangent to find sides of a right triangle using terms like x component and y component and resultant and theta.
7. Given a boat load of vectors on an x and y coordinate system all originating from the origin, be able to identify the ones that have horizontal components, vertical components or both
8. Find the resultant of two nonperpendicular vectors, both size and direction from a reference line
9. Identify common examples of parabolic motion
10. Identify the following in a parabolic graph of a ball shot off a desk:
Where the vertical component of velocity is zero, where the size of the velocity is least and greatest, where two speeds are equal
11. Find time in the air, max height and maximum horizontal distance for a jump given initial speed and angle
12. identify what someone would see from different frames of reference like their perspective or relative to the earth
13. Identify the relative to the earth velocity of two vectors not perpendicular to each other.
