Question
Prepare some exercises on addition and subtraction of algebraic expressions that grade 10 students can use algebra tiles to do.
Solution
Sure, here are some exercises on addition and subtraction of algebraic expressions that grade 10 students can use algebra tiles to do:
-
Addition: a) (2x + 3) + (x + 5) b) (3x^2 + 2x + 1) + (2x^2 + 3x + 4) c) (4x^2 + 3x + 2) + (x^2 + 2x + 1)
-
Subtraction: a) (3x + 4) - (2x + 1) b) (4x^2 + 3x + 2) - (2x^2 + x + 1) c) (5x^2 + 4x + 3) - (3x^2 + 2x + 1)
For each exercise, students can represent each term with algebra tiles. For example, for the term 2x, students can use two "x" tiles. For the term 3, students can use three "unit" tiles. They can then physically add or subtract the tiles to find the result.
