To become greater or larger, as in number, amount, or intensity.
In math, increase means to make something bigger. It can refer to a number getting higher, a shape growing in size, or a value going up. We often use the word when something is added, grows, or moves up.
Here are a few examples:
-
If we have 5 apples and get 3 more, the total increases to 8 apples.
-
If a plant grows 2 inches each week, its height is increasing over time.
-
In a graph, when the line goes up, it shows an increase in values.
We often see the word “increase” in:
-
Word problems involving addition or growth
-
Graphs showing data trends
-
Questions about speed, temperature, or money
When Do Students Learn About Increase in Math?
Students begin to learn about increases when they explore basic operations like addition and start reading word problems with change-over-time language.
Grades 1–2 – Introduction to Increase
Students recognize when numbers go up in number stories or patterns and connect it to addition.
Grades 3–5 – Applying Increase to Word Problems and Graphs
Students describe increases in bar graphs, number patterns, and real-world math situations.
