Leads to
- Recognizing equivalent fractions
- Tenths and hundredths as decimals · Extend the idea
A fraction with denominator 10 or 100 has a decimal name, and both name the same point on the number line.
- Adding and subtracting mixed numbers · See it applied
A mixed number is a point on a number line between two whole numbers, a whole part and a fraction of the next unit.
- Ordering numbers and absolute value · Extend the idea
Distance between two points on a number line is found by counting units, and the same idea measures distance from zero in both directions.
- Probability of one event · See it applied
The chance of an event with equally likely outcomes is a fraction between 0 and 1, so it sits on a number line cut into that many equal spaces, exactly where a fraction of that size is read.
- Approximating roots · See it applied
A square root is placed on the number line between two whole numbers by comparing its square with the squares of those whole numbers.
