Representing Numbers
Maths: Year 3 & 4 National Curriculum, topic 5.1.6
Representing Numbers
We can use objects to represent numbers by counting how many of them are there.
Shapes
- In the picture, each square represents a different number.
- The total amount of all shapes is:
- 500 + 500 + 300 + 300 + 100 = 1,700
Number line
- We can show numbers on a number line.
- The numbers on a number line start at 0 on the left and get bigger as you go to the right.
Place value
- We can use shapes to represent numbers in a place value grid.
- The grid shown represents the number 5,212.
- The thousands column has 5 counters.
- The hundreds column has 2 counters.
- The tens column has 1 counters.
- The ones column has 2 counters.
Test yourself on Representing Numbers
What number is shown in the place value grid?
What is the largest number you can make in the place value grid below with only 2 counters?
Where would you put the number 1,021 on the number line shown?
Where would you put the number 373 on the number line shown?
Where would you put the number 824 on the number line shown?
