Number Lines

Number Lines

You can use number lines in different ways. Use them to find number patterns, to compare numbers, and to locate (find) numbers.

Always pay attention to the questions for each number line. Use the questions to guide your thinking.

**• Study & LEARN:****The term "times as many"**A product (for example, 8) and its factors (2 and 4) can be read as a comparison.

I can compare 8 and 2. 8 is 4 times as many as 2.

I can also compare 8 and 4. 8 is twice as many as 4.

Bar models can be used to understand "times as many."

Bar models can be used to show a comparison:

__• STUDY & LEARN:__*The Distributive Property of Multiplication*What is the distributive property of multiplication?

When multiplying

**a sum**, we may

**multiply each part**of the sum

and then

**add the partial products**.

For example, we know that 5 x 12 = 60.

We can use what we know to examine how distributive property works:

__• STUDY & LEARN:__*F O I L**F O I L*can be used to multiply whenever

**BOTH FACTORS**have two digits.

Choose a different method (distributive property, expanded form, partial products, lattice, or regrouping)

when the factors (

**the numbers you're multiplying**) have more or less than 2 digits.

We can use FOIL to multiply 23 x 41 because

**both factors**have 2 digits.

__• STUDY & LEARN:__*Lattice*Lattice is an algorithm that's hundreds of years old. It's been traced back to India, has been used

in the Middle East, and in Europe. Many students like this method because it helps them to keep track of

their work. However, creating the grid can be a challenge. Students should learn to make the grid

quickly. This is especially important when taking a timed test.

Here are some other ways to learn and to practice lattice multiplication:

__• STUDY & LEARN:__*The terms "factor" and "factor pairs"*A

__is a whole number that divides into another number -without a remainder.__

**FACTOR**For example,

__3 is a factor of 6__because 3 divides into 6

*two times. No remainders!*

**exactly**In contrast, 3 is NOT a factor of 7. Although 3 divides into 7 twice, there is a remainder of 1.

Another way to understand factors:

__are numbers that you can multiply to get another number.__

**FACTORS**For example,

**3**x

**2**= 6 3 is a factor of 6. 2 is also a factor of 6. (So is 1 and so is 6.)

The number 3

*and*the number 2 are

**factor pairs**of 6 because

__6 is the__.
