An algebraic expression would be displayed on the board and students would be asked to determine:
|
|
To simplify an algebraic expression operate on the coefficients of the like terms |
| Like terms - terms which have the same variable and the same power. |
Five algebraic expressions will be presented to the students one at a time where students are asked to identify the like terms and put these like terms into groups by using brackets. Of these five problems, there will be one case where there are no like terms.
|
Students are asked to work in groups of five where they are given cards with terms and expressions and are asked to:
|
| In the case where the expression has no like terms, what do we do? |
| Groups are asked to present their findings and strategy for simplifying the expressions
Students are presented with five more problems to work on individually |
|
Students are selected at random and are given the task of reviewing the salient points of the lesson by guided questioning. Students are directed to the websites stated above |
