## Multiplication Strategies

A quick look at the grade 2 lesson on introduction to multiplication

Taming the tables – Tips to introduce multiplication

### While multiplying always remember :

An even number ** x** an even number = an even number

An odd number **x** an even number = an even number

An odd number** x** an odd number = an odd number

### Distributive property of multiplication

Kids can break apart one of the factors into “easy” addends. I usually advise making one of the addends a 2, 5, or 10 since these are usually easier to compute or are already memorized. This method is using the distributive property.Here are some examples:

#### Scenario 1

#### Scenario 2

### Scenario 3

**Doubling and Halving **

When to use :

- When a problem has one even and one odd factor (or two even factors).
- Remember to Double the odd factor and halve the even factor.
- It’s very useful when the odd factor has a ‘5’in the ones place. because 5 doubled is 10, which is a very easy number to workout mentally

### Some videos that I have created to show more multiplication strategies

### Scenario 1 : Breaking factors by PLACE VALUE

### Scenario 2 : BOWTIE Method

### Scenario 3 : First Out In Last (FOIL) method

F = First (multiply the first two numbers in each set of numbers); O = Out (multiply the two outside numbers); I = In (multiply the two inside numbers); and L = Last (multiply the last two digits, which are the ones).

### Scenario 4 : Lattice method

This method is very helpful when multiplying larger numbers such as those with 2 or more digits. It needs a little practice but very helpful with accurate results.

This method can be divided into 4 steps :

### Step 1 :

Make a table according to the problem given

Eg. For 456 X 32 ; make a table with 3 rows and 2 columns.

For 23 X 44 ; make a table with 2 rows and 2 columns

### Step 2 :

Divide all the boxes into 2 parts diagonally ( you will understand it better after watching the video)

**Step 3 :**

Start mulktiplying from the top row. Tens comes in the top part of the column and ones in the bottom. If there is no value for tens then write ‘0’

### Step 4 :

Add the numbers diagonally. And you have the answer 🙂
