Plot numbers on an interactive visual number line. Perfect for understanding number relationships, ordering, and visualizing positive and negative values.
A number line is a visual representation of numbers arranged in order on a straight line. It helps us understand the relationship between numbers, their order, and their relative positions.
Start at the first number and move right by the second number.
Start at the first number and move left by the second number.
The distance from zero, regardless of direction.
The number further right is always greater.
Read a number line from left to right. Numbers increase as you move right and decrease as you move left. Each mark represents a specific value, and the spacing between marks is equal.
Zero is typically placed in the middle of a number line when showing both positive and negative numbers. It's the dividing point between positive (right) and negative (left) numbers.
Negative numbers are plotted to the left of zero. The more negative a number, the further left it appears. For example, -5 is to the left of -2, which is to the left of 0.
The distance between two points is the absolute value of their difference. For example, the distance between -3 and 5 is |5 - (-3)| = 8 units.
Yes! Fractions and decimals can be plotted between whole numbers. For example, 0.5 or 1/2 would be plotted halfway between 0 and 1.
Start at the first number, then move right (for positive) or left (for negative) by the amount of the second number. Where you land is your answer. For example: 3 + 4 means start at 3, move 4 right, land on 7.
