Algebraic expression list
Copy these or other expressions on pieces of paper so
the Ruler of each team of players can pick the
expression to play. You can also have the Ruler write
an expression which you can approve before the start
of a game. Having the student write an expression
gives them ownership and is an assessment of their
knowledge.
Pick a list or mix the lists depending on the level of
your students. Expand the lists depending on your
students' level. Students should document all work
on their student sheet.
Modifications of the game
• Include expressions that would need to be simplified
by the players such as 2
x + 4 + 3 x - 6. If a player
guesses 5x - 2, they will have to justify the expression
is equivalent to 2
x + 4 + 3 x - 6 which adds another
assessment layer to the game.
• Include expressions in words such as "four less than
twice a number." Have the Rulers pick the expression
from the container and change the words to an
expression for your approval before they return to
their group to play the game.
Example: Four less than twice a number is picked.
The Ruler translates this to 2
x - 4, you indicate if
they are correct, and then they return to their group
to play.
