# P6 Numeracy 10th March

## Decimals - hundredths Lesson 6

Let's put into practise our adding and subtracting skills

Warm-up activity

For today’s warm-up, we are going to solve a Difference Pyramid.  Find the difference between each pair of next-door numbers and write the answer in the circle above. Work your way up one row at a time until you reach the top spot. There are two levels to choose from and, if you need some extra help, use the 100 square provided.

Main activity

On Monday and Tuesday we have been looking at decimal numbers with two digits after the decimal point (hundredths) and we've practised adding and subtracting vertically.

For today's activity, we are going to do some further practice of these calculations.  Watch today's video for more details.

For some questions, you'll need to remember the following:

• If a number does not already include a decimal point, you can add a decimal point after the number and then add one or more zeros
• e.g. 15 = 15.0 = 15.00 (think about money -  £15 is the same as £15.00)

• If a number only has one number after the decimal point (tenths), you can add another zero after the tenths to turn it into hundredths
• e.g. 25.6 = 25.60           48.2 = 48.20

If you get stuck, watch yesterday's Numeracy video which goes through this in more detail.
