Introduction to Multiplication of Money

Hello, Year 4! Today, we are going to learn about multiplying money. This is an important skill because we often need to find out how much things cost when we buy more than one item.

What is Multiplication of Money?

Multiplication means adding the same number many times. When we multiply money, we are finding out the total cost of several items that cost the same amount.

For example, if one toy costs £3, and you want to buy 4 toys, you can multiply the cost of one toy by how many toys you want.

Example

Let’s look at our toy example:

  • Cost of one toy: £3
  • Number of toys: 4

To find the total cost, we multiply:

$$

3 \text{ (cost of one toy)} \times 4 \text{ (number of toys)} = 12

$$

So, the total cost is £12.

Key Rules for Multiplication of Money

  1. Line Up the Decimal Point: When you multiply amounts of money, always line up the decimal point if you’re writing it down.
  2. Convert to Whole Numbers: Sometimes, it’s easier to think of money in pence. For example, £1 = 100 pence.
  3. Use Times Tables: Remember your times tables! They can help you quickly find the answer.

Tips and Tricks

  • Break It Down: If you find a big number hard to multiply, break it into smaller parts. For example, to multiply £5 by 6, you can think of it as £5 × 5 + £5 × 1.
  • Use Visuals: Drawing pictures or using counters can help you see how many items you are buying.
  • Practice with Real Money: Use real coins so you can practice counting and multiplying.
