## What is number sense?

## By Bob Cunningham, EdM

## At a glance

Number sense refers to a group of key math abilities.

It includes the ability to understand quantities and concepts like more and less .

Some people have stronger number sense than others.

- Understanding quantities
- Grasping concepts like more and less , and larger and smaller
- Understanding the order of numbers in a list: 1st, 2nd, 3rd, etc.
- Understanding symbols that represent quantities ( 7 means the same thing as seven )
- Making number comparisons (12 is greater than 10)
- Recognizing relationships between single items and groups of items ( seven means one group of seven items)

## Dive deeper

Examples of trouble with number sense.

Here are examples of what it looks like when people struggle with number sense.

The number of beads has shrunk

Subtracting the two beads means the group of seven is now a group of five

The group of beads has gotten larger

Adding three beads to the pile of seven makes it a pile of 10

## How schools can help

In that case, schools usually turn to an intervention process, where kids typically:

Work with “manipulatives” like blocks and rods to understand the relationships between amounts

Do exercises that involve matching number symbols to quantities

Get a lot of practice estimating

Learn strategies for checking an answer to see whether it’s reasonable

Talk with their teacher about the strategies they use to solve problems

Get help correcting mistakes they make along the way

Learn about intervention systems like RTI or MTSS .

## How to Find the Mean

The mean is the average of the numbers.

It is easy to calculate: add up all the numbers, then divide by how many numbers there are.

In other words it is the sum divided by the count .

## Example 1: What is the Mean of these numbers?

## The Mean is 8

It is because 6, 11 and 7 added together is the same as 3 lots of 8:

It is like you are "flattening out" the numbers

## Example 2: Look at these numbers:

3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29

The sum of these numbers is 330

The mean is equal to 330 / 15 = 22

## The mean of the above numbers is 22

Knowing this, let us try an example:

## Example 3: Find the mean of these numbers:

- The sum of these numbers is 3 − 7 + 5 + 13 − 2 = 12
- There are 5 numbers.
- The mean is equal to 12 ÷ 5 = 2.4

## The mean of the above numbers is 2.4

Here is how to do it one line:

Mean = 3 − 7 + 5 + 13 − 2 5 = 12 5 = 2.4

## Try it yourself!

Now have a look at The Mean Machine .

## Prime Numbers

Prime numbers are the natural numbers greater than 1 with exactly two factors, i.e. 1 and the number itself.

## What are Prime Numbers?

The first ten primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 .

Note: It should be noted that 1 is a non-prime number. It is a unique number.

This is not of the form 6n + 1 or 6n – 1.

Hence, 10 is not a prime number.

Find if 53 is a prime number or not.

The only factors of 53 are 1 and 53.

Let us write the given number in the form of 6n ± 1.
