The purpose of this activity is to have some fun doing expression work. Students will substitute information into an expression with the end result being their birthday. Feel free to use calculators to make this a quick exercise. Here is the expression.

X = Month Of Your Birthday

Y = Day Of The Month Of Your Birthday

Note the vast amount of grouping symbols the kids will need to keep track of.

Example: My birthday is November 21st

x = 11

y = 21

My Math is thus

7(11) = 77

77 - 1 = 76

76(13) = 988

988+ 21 + 3 = 1012

1012(11) = 11132

11132 -11 -21 = 11100

11100/10 = 1110

1110 + 11 = 1121

1121/100 = 11.21 (11.21 is my b-day)
