Patterns

Today in math we started a new unit on patterns. We worked on equations today. An equation is the whole part and the letter is called a variable because the value of the letter can be changed.
ex: 4 y, y= 7
4 y is the equation and y is the variable.
4(7)= 28

3+x, x=5
3+z is the equation and x is the variable.
3+5+8
