We can count in steps of 1,000 and 10,000 up to 1,000,000 (one million).
We can order numbers up to 1,000,000 and know the value of each digit.
Year 5 Unit 1b
What we are learning:
- We are extending our knowledge of the number system to higher numbers up to 1,000,000
- Counting aloud in sequences of higher numbers helps to reinforce the patterns
- Writing numbers as you say them will strengthen the understanding of place value i.e. what each digit is worth
- When we use a place value chart we can see that the value of any digit is 10 times bigger each time we move one column to the left:
- In order to help us read large numbers we use commas for numbers bigger than 1,000 like this:
1,000 = one thousand
10,000 = ten thousand
100,000 = one hindered thousand
1,000,000 = one million (note the extra comma that separates the million from the thousands)
ACTIVITY 1: IDENTIFYING THE VALUE OF DIGITS IN LARGE NUMBERS
ACTIVITY 2: ORDERING LARGE NUMBERS
Activities you can do at home:
Numbers to 1,000,000 (one million)
1. Write the number 1,000,000 on a piece of paper. Ask your child how many columns would be needed for a place value chart up to 1,000,000 (seven)
2. On a sheet of paper ask your child to draw a place value chart with columns from units to 1,000,000 and label the name of each column from units to million
3. Write down different numbers and then ask your child to write each digit on a post it and place it in the correct column e.g. 1,245.854
4. Examples are on the activity sheet
You and your child each write a variety of numbers on different pieces of paper. Then ask your child to put them in order from highest to lowest or lowest to highest. Vary the difficulty by adding negative numbers or decimals. Examples are on the activity sheet
Good questions to ask:
Can you read this number out loud?
What value does this digit represent in this number?
Which number is 1000 bigger/smaller than this one?
If your child:
Gets confused when ordering larger numbers
Use a place value chart to lay out the columns and talk about the value of each column (as above). Always say the numbers out loud together so that the sound of the words can be matched to the columns. Point to each part of
the number as you say it. Remember that using commas in the right places will help you know how to say a big number.
Please use this activity when you think your child understands the unit of work. It will deepen and extend your child’s understanding of this unit.
