Students at Years 7 and 8 start using forward tracking flowcharts to develop algebraic equations. The concept is revisited at Year 8 when backtracking is introduced in order for students to learn how to solve for unknown pronumerals in algebraic expressions. Fundamental is the knowledge of BODMAS and opposite operations.
This package provides adjunct instruction to complement direct teaching of the forward and backtracking concepts, as well as a revisitation of opposite operations. BODMAS and BIDMAS are mentioned in such a way that the Teacher may then revisit these important areas during the sequence, as required.
Students are provided with 36 graded task cards that will enable them to practice both forward and backtracking to solve unknown pronumerals in both mathematical and worded questions.
There are manipulative materials that can be printed on white card or paper, laminated and used for those students needing a large visual to construct the appropriate forward and back tracking flow charts. The students can then write the charts in the workbook once they are satisfied they have the correct solution. A solution sheet has been included with the final answers only.
The teaching format is flexible for individual and paired groups for the task cards, whilst the Powerpoint instruction is appropriate for whole group teaching. Whole class sharing of the task card process is an option.
I have used this method extensively and successfully in a Year 8 Algebra class to develop a sound understanding of opposite operations in solving unknown pronumerals in algebraic expressions. The instructional powerpoint is sufficiently flexible to not only provide a framework for instruction, but highlights areas where additional support may be required. A good foundation in this concept is essential for students in order to offset some of the early issues that later emerge with transposition of equations.
Included in the package: One Powerpoint, 36 Task cards, Answer Key and Ready-to-Print manipulatives for lamination and use as a concrete teaching resource for this learning sequence.
Projected theaching time: 3hrs maximum for a mixed-ability classroom.
