Study Notes
Comparing Numbers
- Numbers can be compared using greater than (>), less than (<), or equal to (=) symbols.
- When comparing numbers, start with the largest place value.
- If the digits in the largest place value are the same, compare the digits in the next largest place value.
- This process continues until a difference is found, determining which number is greater or less.
- For example, in comparing 34,051 and 36,200, both numbers have 3 ten thousands, so the thousands place is compared.
- Since 6 thousands is greater than 4 thousands, 36,200 is greater than 34,051.
- The place value chart can be used to represent numbers and help visualize their comparison.
- Expanded form and expanded notation are helpful strategies to compare numbers by breaking them down into their place value components.
Place Value and Number Representation
- Place value chart can be used to represent number values (thousands, hundreds, tens, ones).
- The units in the place value chart correspond to powers of ten, with each place value representing a tenfold increase.
- The chart is useful for understanding the relationship between digits and their positional value.
