# All maths resources

Below is a list of maths resources that you can use to teach or practice particular skills.

## Skip counting in 2s, 5s, and 10s

Skip counting is a great way to start multiplication. By learning to count up in groups of numbers, students can start practicing their times tables. Skip counting involves skipping the amount of numbers you're counting up in.

For example, if you are skip counting in 2s and start at 0, you would count 0, , 2, , 4... and so on.

If you are skip counting in 5s starting at 0, you would count 0, , , , , 5, , , , , 10... and so on.

## Converting between numbers and words

For example:

1 becomes "one"

2 becomes "two"

10 becomes "ten"

20 becomes "twenty"

45 becomes "forty-five"

129 becomes "one hundred and twenty nine"

## Identify basic fractions

Fractions can be a tricky concept for students to first grasp. Starting with splitting up shapes and foods like pizza or cake is a great introduction to fractions.

To start with, it's important to break down what a fraction is: a small part of a whole.

It's also important to understand the parts of a fraction. The bottom number is called the "denominator" and tells us how many pieces there are in total. The top number is called the "numerator" and tells us how many pieces we actually have. So if we take 2 slices of a pizza that has 8 slices, we have 2/8 of the pizza!

## Understanding operators

+ means to add or plus

- means to subtract or minus

× means to multiply or times

÷ means to divide

= means to be the same, two quantities have the same value

## Logical reasoning and guess the number

Using logical reasoning, students can guess the number based on initial information.

For example:

The number I'm thinking of is a multiple of 4, greater than 16 but smaller than 24. (I am 20)

I am an even number. I have a five in the tens place. You do not say me when you count by tens. I am greater than 0 but less than 54. (I am 52)

Tom 16. Emma is 1 year younger than Tom and 3 years younger than Matt. How old is Matt? (Matt is 18)

## Doubling and halving

Doubling is the process of making twice as much of something, or two lots of it. For example, if I wanted to double 6 sweets, I would add another 6 sweets to make 12. I would have twice as much as I did before.

Halving is the process of splitting into two groups and removing one of them. If I wanted to halve my 6 sweets, I would split them into 2 groups of 3, and get rid of one group. I would be left with 3 which is half of 6.

## Multiplying large numbers

Multiplying any numbers by 3 digits or more can be a little more complex and require more steps than multiplying by single digit numbers. However, multiplying by large numbers is still based on basic knowledge of times tables.

Let's look at an example and break it down.

If we have the question 34 x 23 = ?

We automatically know that this question is not covered by our times tables to 12 but we can use our basic times tables knowledge by splitting up the question.

We can start by splitting the question into two:

34 x 20 = ?

34 x 3 = ?

We have split 21 into 20 and 1. We can split it up even further though.

30 x 20 = ?

4 x 20 = ?

30 x 3 = ?

4 x 3 = ?

This is a little simpler to work out and a lot closer to our basic times tables knowledge!

We know:

30 x 20 = 600

4 x 20 = 80

30 x 3 = 90

4 x 3 = 12
