These activity sheets will give your students a review of multiplication using addition and grouping.

What is Multiplication? Someone mathematically solves a pair of numbers to derive a third number, i.e., a product. For positive integers, we multiply by adding multiplicand to itself a particular number of times. If we are multiplying 6 by 3, it means we will add 6 to itself three times. We can also multiply real numbers as per the laws directing the multiplicative properties of positive integers. In short, multiplication is the process in which we add numbers itself repeatedly. So, this method is also a repeated addition. Understand the mathematical distribution of multiplication: Product - it is a number that we get after multiplying two different numbers. Multiplicand - number of digits in each set. Multiplier - it is a number of such equal set. Multiplication signs: There are different signs to express the process of multiplication while solving its questions mathematically. So, those are, x (cross), * (asterisk), . (dot). Understand it by the following expressions; => 5 x 4 => 5 * 4 => 5 . 4 => 5 times 4 Also, we can use the multiplication method in solving variables for algebraic expressions. For examples; => ab = a x b => (a + 1) (b + 1) = (a + 1) x (b + 1)

Students can start to really grasp multiplication quickly when they see it as just repeated addition. By the time students are confronted with multiplication their addition skills have to be sick. You can easily show students that four time three is the same as adding four to itself three times. This will start them focusing in the right direction from here it is up to them to transition to a full blown times tables. These worksheets explain how to do multiplication problems using addition and grouping. Students will convert simple groupings into multiplication equations, rewrite addition equations, multiply decimals, and more.

Multiplication Concept Lesson

Write the addition sentences as multiplication or vice versa and solve. Multiplication has to do with many groups of the same size. 5 x 3. means three groups of 3. The order of multiplication does not matter: 3 x 5 and 5 x 3 are both 15.

Multiplying Decimals by Whole Numbers Lesson

Write multiplication as a repeated addition, and solve: 3 x 1.2 =. Multiplication by a whole number is repeated addition. 3 x 1.2 means adding three times 1.2 i.e. 3 x 1.2 = 1.2 + 1.2 + 1.2 = 3.6.

Multiplying Decimals in Columns Lesson

Write multiplication as a repeated addition, and solve: 3.7 x 4 = Multiplying decimals in columns happens the same way as if they were whole numbers. Once you have the answer, put a decimal point in it.

Lesson and Practice

The answer lacks a decimal point. Put it in the right place. 1. Multiply the numbers just as if they were whole numbers. The answer is already shown, but the decimal point is missing. 2. Now we have to put the decimal in the right place. Place the decimal point in the answer by starting at the right and moving the number of places equal to the sum of the decimal places in both numbers multiplied. Here, the decimal is one position away from the right. So we put the decimal one place from the right i.e. before 8.
