Variables help students solve patterns and simple equations.<\/li>\n\n\n\n<li><strong>Example:<\/strong>&nbsp;In x + 5 = 10, the letter x is the variable. It stands for the missing number, which is 5.<\/li>\n\n\n\n<li><strong>Fun Application:<\/strong>&nbsp;Write v + 3 = 9 on paper.

In some shapes, like an isosceles triangle, the vertex angle is the angle between the two equal sides.<\/li>\n\n\n\n<li><strong>Example:<\/strong>&nbsp;The top angle of an isosceles triangle is often called the vertex angle.<\/li>\n\n\n\n<li><strong>Fun Application:<\/strong>&nbsp;Draw an isosceles triangle.
