Benchmark angles
Benchmark-angles 256
Description
Exercise Name: Benchmark angles
Math Missions: 4th grade (U.S.) Math Mission
Types of Problems: 4

The first instance of Benchmark angles is under the 4th grade (U.S.) Math Mission. This exercise increases experience and comfort with the standard angles that one sees in mathematics.

Types of Problems[]

There are four types of problems in this exercise:

  1. Measure of the angle: This problem has and angle drawn and the student selects the correct measure of the angle from a set of multiple choice possibilities.
    BA1

    Measure of angle

  2. Which angles measures?: This problem gives a number and asks the student to select which of the pictures is open to that angle. It does not always use just an angle, but it will sometimes have polygons as the multiple choice options.
    BA2

    Which angle measures?

  3. Label all the angles: This problem has a shape drawn and the student selects the measure of all the angles in particular diagram.
    BA3

    Label all the angles

  4. Real life angles: This problem describes various real-life scenarios and asks the student to recognize what angles are formed in the particular situation.
    BA4

    Real life angles

Strategies[]

This exercise is medium to get accuracy badges user has to be careful on some of the angles that are close to each other. It is medium to get speed badges (4 sec) because many of the problems take a fair amount of time to read and think about, but they do repeat fairly often.

  1. The selection problems are rarely (if ever) "None of These".

Real-life Applications[]

  1. Engineers and architects use angles for designs, roads, buildings and sporting facilities.
  2. Athletes use angles to enhance their performance.
  3. Carpenters use angles to make chairs, tables and sofas.
  4. Artists use their knowledge of angles to sketch portraits and paintings.
