Division with remainders. Your child will most likely come across or ask about situations where division “does not work.” These can be explained with the introduction of the remainder. It is an important idea to understand as the division of larger numbers will require the “carrying” of this remainder.
When adding fractions without a common denominator, it is necessary to find a common denominator before adding the numerators. Find two equivalent fractions by determining the least common multiple of the two denominators and using that as the denominator for both fractions.
Start by following the basic process for fraction multiplication, turning any mixed fractions into improper ones. Before you cross cancel or multiply, however, swap the numerator and the denominator in the second fraction. This is called taking the reciprocal and it is the key step to turn this into a division operation. Then, cross cancel, multiply across to get the answer fraction, and reduce.
One of the first skills students learn is addition. Addition is the natural advance after counting. Many students do not grasp this basic skill properly. As a result, students find it difficult to advance to higher level skills and they get stuck. Therefore, to make the task easier, here are five easy ways to learn addition. You may have heard of some of these games, they go by many different names. In addition to some simple games, we offer up some techniques to keep in mind when adding numbers in general. If you are already good at addition, you will still find these tips helpful to make you faster at addition.
