Place Value 7685432

What you need to know E3 –L2 Money, rounding, basic four rules. Understand common measures to one decimal place (1.5 metres) and money to two decimal places (£2.37). Understand the decimal point separates pounds and pence, m and cm. Understand how zero as a place holder, £1.05 and as leading zero, £0.35 and 0.5 m.  Add, subtract, multiply, divide ( Using a calculator) and record sums of money. Order, approximate and compare decimals. Calculate and estimate amounts of money and ( L2 ) convert between currencies. Add, subtract, multiply and divide ( Using a calculator) decimals up to three places and check answers in the context of measurements and money, for example a bill for £32.67 shared equally among three people.

Diagnostics Questions List the following numbers in ascending order. (a) 0.6, 0.23, 0.8, 0.1 ……………………………………… (b) 4, 0.7, 3.6, 1.9 ……………………………………… (c) 1.43, 1.5, 1.7, 1.099 ……………………………………… (d) 0, 1.0, 0.87, 1.25 ……………………………………… (e) 1.09, 1.90, 1.11, 1.2 ………………………………………

Rounding to whole number, 1dp and 2dp Rounding is when you make a number simpler, but keeping its value close to what it was. 73 Remember: If it’s between 1-4 it rounds down, 5-9 it rounds up! Look at the number directly to the right Round to the nearest 10 Is it closer to 70 or 80?

Rounding to whole number, 1dp and 2dp Rounding decimals works exactly the same. We’re looking at how many numbers are left after the decimal place. Round 1.436 to 1dp Answer: 1.4 Now round 1.436 to 2dp We need to round this so there is just 1 number after the decimal This number will either stay the same or round up This number is the ‘deciding’ number

Diagnostics Questions Round the following to the nearest whole number (a) 1.35 ……………………………………… (b) 3.64 ……………………………………… (c) 10.50 ……………………………………… Round the following to 1 decimal place (1dp) (a) 1.35 ……………………………………… (c) 10.50 ………………………………………

Adding and Subtracting The golden rule: The decimal points MUST be aligned before adding and subtracting the numbers. This technique doesn’t just work for money. It works for any decimal addition as long as you align the decimal points.

Adding and Subtracting £3.22 13.70 + - £5.71 0.56 Make sure the decimals line up! Can you add and subtract these decimals?

Diagnostics Questions Can you answer the following calculations? (a) 1.35 + 2.20 (b) 2.67 + 0.07 (c) 5.50 – 3.22 (d) 10.00 – 5.89

Multiplying and Dividing by 10, 100 & 1000 What is 5.5 x 100? What is 10.67 ÷ 10?

Diagnostics Questions Can you answer the following calculations? (a) 3 x 4.30 (b) 2 x 3.33 (c) 10.00 ÷ 5 = (d) 8.80 ÷ 4 =

Estimating

Diagnostic Questions Can you estimate the cost of the following? (a) 8 bottles of water costing £0.80 each (b) 6 pens costing £1.05 each (c) 3 sausage rolls costing 45p each (d) 19 muffins costing 99p each

Multiplying

Writing measurements with decimals When we write measurements we often use decimals to separate the ‘whole’ number, from the ‘parts’ of a whole number. How would you write 325 cm in metres?
