Students use their algebra skills to decode a message from aliens! It's a lot of fun and a great activity for the end of the year.
-solving one-step equations using inverse operations and number sense
-translating written descriptions into algebraic equations
-general problem solving skills
-- An encrypted message from aliens
-- Two sets of 26 equations with a variable for each letter of the alphabet. One set uses friendlier numbers that students can *mostly* solve using number sense, the harder set will require the use of inverse operations.
-- PPT Presentation introducing the backstory:
Early this morning NASA intercepted a message from aliens. It's written in a code that the scientists at NASA can't read. A few minutes later the aliens sent another message: a bunch of equations. Your task is to help NASA figure out why the aliens sent math problems - and what the message says!
** The equations and the PPT are editable to meet your students needs!
