First
True or False, patterns must be made up of numbers
False

3rd
This type of pattern increases or decreases following a specific rule.
Growing Pattern

12 - 5 = 7
This symbol means that the two sides of the equation are not the same
not equals symbol
This addition strategy is when you use manipulatives to help solve the problem
Using objects (cubes)
This is the ending for all ordinal numbers after 3
