This unit is full of basic computational skills that children will use often, and skills that children must master to succeed in higher levels of mathematics. Your child will develop strategies for multiplying and dividing whole numbers. They will use multiplication charts, counters, and calculators.
It is important that students understand the following:
In a multiplication sentence, the numbers being multiplied are FACTORS and the answer is called a PRODUCT.
An ARRAY is a picture made up of dots that are put into rows and columns. In a multiplication sentence, the first factor tells the number of rows, and the second factor tells how many dots are in each row. Arrays can help show that changing the order of the factors does not change the product.
Remember that when multiplying, "times" also stands for "groups of". Therefore, even though the answer is the same, 6 groups of 5 (6x5) and 5 groups of 6 (5x6) are two different questions, especially when asked to draw a picture, or identify what a picture shows.
When dividing, "divided by" also stands for "shared by". Therefore, 30 shared by 5 (30 divided by 5) is different than 30 shared by 6 (30 divided by 6) and you will get two different answers.
Skip Counting is an excellent way to help your child practice. Once they master skip counting they will be able to transfer that knowledge to the basic multiplication and division facts.
