Coursework Instructions:

Using the textbook-"A Problem Solving Approach to Mathematics for Elementary School Teachers"
from chapters 4-6 answer the following questions..
1. Discuss various models for integer multiplication and division. What are the advantages and disadvantages of each method? Which method would you use to teach this topic?
2. Discuss the divisibility rules for the numbers 2 through 10. What is the value of knowing and understanding these rules? Give an example of how you would use these rules.
3. How would you teach the concept of multiplication of fractions? If a student doesn’t understand it this way, what alternate method can you use?
4. What are equivalent fractions? Explain how two fractions can be equivalent. Give practical examples of fractions that are equivalent. How would you teach this concept to a class?

1 Integer multiplication and division models
* Number line model
The learner moves in right or left directions on the number line to reinforce the opposite’s idea. The multiplication concept is supported as repeated addition, while division is reinforced as a repeated subtraction (Billstein et al., 2021). Despite the method being easy and quick when done repeatedly, its major disadvantage is that it is limited to whole numbers only but not fractions.
* Chip model
The model used manipulatives, presenting it to learners as a hand-on operation. It stresses the idea of opposite integers totalling zero (Billstein et al., 2021). In contrast to the number line model, this method is more complex to work with or understand. Overall, the best way to use in teaching this topic would be the number line model.
2 Divisibility of 2 through 10
A number is divisibly by

When

2

It ends in 0, 2, 4, 6, or 8

3

The sum of its digits is divisible by 3. For example, 27 gives 9, while 22 gives 4. Therefore 27 is while 22 is not divisible by 3

4

The last two digits are divisible by 4, such ...
