Mix-Pair-Share:
-variable
Students mingle around the classroom to music, when the music stops, they raise their hand, pair up with the person closest to them, high five and share (topic of sharing is chosen by the student who has the ball in their hand and which number their right thumb lands on).
-expression
Activities: Canadian Animals – with sounds What is a variable? Definition: A variable is a letter or symbol that takes the place of a number in an equation. -Model and challenge students to solve the equation for the variable.
-equation -opposite operations
Venn Diagram – Expression vs. Equation -Use examples to show that the equal sign is the difference between an expression and an equation. Definition of Expression: Each quantity may be a number. Definition of Equation: One quantity equals another quantity.
100 = 100 One Side = The Other Side -One quantity equals another quantity & both sides of the statement are equal. -If you have 6 bears on one side of the ‘=’ then how many go on the other side to balance the equation? 6!
Opposite Operations -Doing opposite operations. What you do to one side, you must do to the other side! -We must use operations (+ - x ) to do so – only addition and subtraction today. -Do 2 examples on Smart Notebook as a class, do a few more example on IXL as a class.
“Canadian Eh!” Scavenger Hunt where students have to go around the classroom, using expressions to solve equations to fill in their scavenger hunt word search. When they are done, they get a Canadian candy prize! Canadian Eh!
*A workbook will be made with a page that corresponds to each concept/slide from the Smart Notebook. *
Conclusion: Mix-Pair-Share: Students mingle around the classroom to music, when the music stops, they raise their hand, pair up with the person closest to them, high five and share (topic of sharing is chosen by the student who has the ball in their hand and which number their right thumb lands on).
