We can read, write and understand numbers up to and over 1 million
Year 6 Unit 15
What we are learning:
- We are extending our knowledge of the number system to higher numbers up to and beyond 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
- Using commas in larger numbers helps e.g. 23,543,765
- Looking at individual digits in a large number and being able to identify their value is important e.g. the 5 in 54,376,137 is 50 million
- Revisit how we use the zero place holder so in 4,807,231 we say four million eight hundred and seven thousand two hundred and thirty one
- Using a place value chart can remind children about the value of each digit:
ACTIVITY 1: MISSING NUMBERS GAME
ACTIVITY 2: FUN WITH LARGE NUMBERS
Activities you can do at home:
Play the ‘Missing numbers game’ – a game for 2 players.
What you need: pencil and paper and pen
How to play:
1. Player 1 says (or writes down a sequence) of 5 numbers between 100,000 and 99,000,000 (by adding or subtracting a constant amount each time) but with 2 numbers from the pattern missing.
E.g. 1,825,000; 1,835,000;(gap); 1,855,000; 1,865,000; (gap);1,885,000
2. Player 2 has to work out what is happening to the numbers i.e. how to get from one number to the other and then use this to say or write the missing two numbers in the sequence. E.g. 1,845,000 and 1,875,000
3. Score a point for each correct number given and 2 bonus points for being able to explain how to get from one number in the sequence to the next E.g. Adding/increasing by 10,000.
4. Swap roles
5. The first player to score 20 points is the winner.
Reading and writing large numbers- an activity for 2
Take it in turns to write down a large number and show it to your partner.
They have to read out the number. Try writing it in words as well as numbers
Take it in turns to say a large number which your partner then has to write down in numbers and words.
See examples on the activity sheets
Good questions to ask:
Which number is 10,000 bigger than…….
How do we say this number?
If I say this number can you write it down in digits?
If your child:
Gets the values of different columns mixed up in large numbers
Use a place value chart and label the columns together until s/he becomes more confident. This may take some time and practice.
