### PRODUCT DESCRIPTION

Bring EARTH DAY awareness to your math class.

There are 5 different Earth Day activities for April 22 or any day!

Four of the puzzles can be done by any class from pre-algebra to calculus.
The fifth includes parallel lines cut by a transversal, a topic from 7th and 8th geometry and used in HS Geometry and beyond.

--------------------------------------------

WORD SEARCH The word search starts with a brief writing about Earth Day. Eleven words are lightly underlined in the reading. These words are hidden in the word search. Students circle the words in the search field to complete this activity.

(2) SYMBOL PUZZLES: Discover the integer value of each symbol. This can be done by logical thinking; i.e. identifying which numbers must be even or odd and how they combine to form the sums. OR these puzzles can be solved by setting up systems of equations or by using augmented matrices (reduced row echelon form). I prefer to let students use whatever mathematical reasoning they have in their arsenal. There are two puzzles included; one with three symbols, one with four.

LOGIC PUZZLE: All the information to solve a logic problem is included in the introduction and clues. Logic puzzle are great “thinking” activities.

RIDDLE: Students answer the questions about parallel lines cut by a transversal (finding the measure of angles). Each answer corresponds to a letter which replaces the question number. The code will give the answer to the riddle. Remind them to read/solve carefully and NOT to assume they know the answer!

If you can’t plant a tree, enjoy these activities as part of your Earth Day!

OR make any day Earth Day . . . we should always care about our planet!
