I can explain how to compare numbers with up to 8-digit numbers.
Lesson details
Key learning points
- The number of digits can help when ordering numbers - usually the more digits, the greater the number.
- When comparing numbers, the greatest value digit that is different determines the greater number.
- The stem sentence: 'the value of the digit in the ___ column is ___’ supports us to compare numbers.
Common misconception
Children may think that the greater value number is the one that starts with the greater value digit even if the number has fewer digits overall.
When comparing numbers, compare the value of the digits not the digits themselves. If both numbers have the same amount of digits, so we need to compare the largest place value digit that is different.
Keywords
Compare - When we compare numbers, we determine whether a number is smaller than, greater than or equal to another according to similarities and differences in their values.
Inequality - An inequality compares values and is used to show that one number is not equal to another. The symbols < and > are used to indicate less than (<) or more than (>).
