'Triangular numbers' for 5th grade
Triangular numbers
In this topic you are asked to look at a series of numbers from the Triangular numbers series and fill in the missing number.
Triangular numbers are a sequence of numbers that can be arranged in the shape of a triangle. The first triangular number is 1, the second is 3, the third is 6, the fourth is 10, and so on.
To understand how these numbers work, imagine arranging objects in the shape of a triangle.

For example, if you arrange 3 objects, you can make a triangle with one object at the top and two objects on the next row. If you arrange 6 objects, you can make a triangle with one object at the top, two objects on the second row, and three objects on the third row.
The equation for working out the nth value in the series is Tn = 1 + 2 + 3 + ... + n
Triangular numbers show up in many places in math and science, from counting the number of dots in a triangular grid to understanding the properties of certain types of molecules.
