Answer to Question #314828 in Algebra for Nandi

Question

1. Use any strategy to teach compensation concept of 453+96 to a grade five class. Explain the process in full. State the purpose of teaching compensation in mathematics. (2)

2 The traditional way of teaching mathematics is to make learners memories concept. Student invented strategies is suggested in the teaching and learning of mathematics concept. In your view, do you think this new strategy will assist in the development of understanding of mathematics.

Answer 1

1) Compensation in math

Compensation in math is the process of reformulating an addition, subtraction, multiplication, or division problem to one that can be computed more easily mentally.

The addition of 453+96 giving (453+90+6)=549

2)Yeah....there are some STRATEGIES FOR INCREASING STUDENT MOTIVATION IN MATH

1. Call attention to a void in students’ knowledge: Revealing to students a gap in their understanding capitalizes on their desire to learn more. For instance, you may present a few simple exercises involving familiar situations, followed by exercises involving unfamiliar situations on the same topic. The more dramatically you reveal the gap in understanding, the more effective the motivation.

2. Show a sequential achievement: Closely related to the preceding technique is having students appreciate a logical sequence of concepts. This differs from the previous method in that it depends on students’ desire to increase, not complete, their knowledge. One example of a sequential process is how special quadrilaterals lead from one to another, from the point of view of their properties.

3. Discover a pattern: Setting up a contrived situation that leads students to discover a pattern can often be quite motivating, as they take pleasure in finding and then owning an idea. An example could be adding the numbers from 1 to 100. Rather than adding the numbers in sequence, students add the first and last (1 + 100 = 101), and then the second and next-to-last (2 + 99 = 101), and so on. Then all they have to do to get the required sum is solve 50 × 101 = 5,050. The exercise will give students an enlightening experience with a truly lasting effect. There are patterns that can be motivating, especially if they are discovered by the student—of course, being guided by the teacher.

4. Present a challenge: When students are challenged intellectually, they react with enthusiasm. Great care must be taken in selecting the challenge. The problem (if that is the type of challenge) must definitely lead into the lesson and be within reach of the students’ abilities. Care should be taken so that the challenge does not detract from the lesson but in fact leads to it.

5. Entice the class with a “gee whiz” mathematical result: There are many examples in the mathematics realm that are often counterintuitive. These ideas by their very nature can be motivating. For example, to motivate basic belief in probability, a very effective motivation is a class discussion of the famous birthday problem, which gives the unexpectedly high probability of birthday matches in relatively small groups. Its amazing—even unbelievable—result will leave the class in awe.

6. Indicate the usefulness of a topic: Introduce a practical application of genuine interest to the class at the beginning of a lesson. For example, in high school geometry, a student could be asked to find the diameter of a plate where all the information he or she has is a section of the plate that is smaller than a semicircle. The applications chosen should be brief and uncomplicated to motivate the lesson rather than detract from it.

7. Use recreational mathematics: Recreational motivation involves puzzles, games, paradoxes, or the school building or other nearby structures. In addition to being selected for their specific motivational gain, these devices must be brief and simple. An effective execution of this technique will allow students to complete the recreation without much effort. Once again, the fun that these recreational examples generate should be carefully handled, so as not to detract from the ensuing lesson.

8. Tell a pertinent story: A story of a historical event (for example, the story of how Carl Friedrich Gauss added the numbers from 1 to 100 within one minute when he was a 10-year-old in 1787) or a contrived situation can motivate students. Teachers should not rush while telling the story—a hurried presentation minimizes the potential motivation of the strategy.

9. Get students actively involved in justifying mathematical curiosities: One of the more effective techniques for motivating students is to ask them to justify one of many pertinent mathematical curiosities, like the fact that when the sum of the digits of a number is divisible by 9, the original number is also divisible by 9. The students should be familiar and comfortable with the mathematical curiosity before you challenge them to defend it.

Teachers of mathematics must understand the basic motives already present in their learners. The teacher can then play on these motivations to maximize engagement and enhance the effectiveness of the teaching process. Exploiting student motivations and affinities can lead to the development of artificial mathematical problems and situations. But if such methods generate genuine interest in a topic, the techniques are eminently fair and desirable.
