Why do students struggle with fractions?
Many kids fear fractions because they don’t understand how they work – they mix up the parts and don’t understand what they mean and what we do to them. They have perceived fractions as being too hard for them before even having the chance to try.
Why are fractions so difficult?
The biggest reason fractions are so difficult is because each fraction with a different denominator is in an entirely different number system! In a fraction, the denominator tells you what base you’re in. But even these number are related to our basic “Base 10” numbers. Think about the most common fraction: 1/2.
How do you find the problem with fractions?
Subtract fractions with the same denominator by subtracting the numerators. If you need to subtract fractions, they must have the same denominator, just like if you were adding them. All you have to do is subtract the smaller numerator from the larger numerator to solve the problem.
How do you teach adding fractions with different denominators?
Here’s the traditional way to add fractions with two different denominators:
- Find the LCM of the two denominators. Suppose you want to add the fractions 3/4 + 7/10.
- Increase the terms of each fraction so that the denominator of each equals the LCM.
- Substitute these two new fractions for the original ones and add.
Why are fractions so important?
Fractions are important because they tell you what portion of a whole you need, have, or want. Fractions are used in baking to tell how much of an ingredient to use. Finally, fractions are used to determine discounts when there’s a sale going on.
