Pearson Lightbook StarterLightbook Starter is an innovative digital resource powered by Pearson’s award-winning Lightbook technology. It has been developed to help students learn key mathematical concepts, evaluate their understanding and track their progress. ‘Before you begin’ sections assess learner readiness before each chapter topic, while ‘Check-in’ questions can be used to evaluate learner understanding and practice after every chapter section.
Auto-correcting questions are linked to the Progress Tracker dashboard for easy analysis and viewing of results, which are mapped to progression through the Student Book as well as to Australian Curriculum: Mathematics and Victorian Curriculum: Mathematics content descriptions.
Pearson eBookMuch more than just pages on a screen, Pearson eBook is an online or offline version of your Student Book linked to interactive content, rich media resources and other useful content specifically developed for Mathematics. It supports you with appropriate online resources and tools for every section of the Student Book, including videos, eWorked Examples, interactive lessons, worksheets and more. Teacher resources include chapter tests, full teaching programs and curriculum mapping for the Australian Curriculum: Mathematics and for the Victorian Curriculum: Mathematics.

Inequalities jigsawEquipment required: scissors, pen, ruler, graph paper and Appendix 1H
This activity is similar to a jigsaw puzzle, but involves matching an inequality with its solution and its graph. This game can either be played individually or in pairs. A copy of the jigsaw is provided in Appendix 1H.
1 Cut out the jigsaw, making sure that all cuts are made along the bold lines.
2 Students need to place the pieces together so that the sides are adjacent to their equivalent pair. Some students may need to complete the associated working on graph paper before they can arrange the pieces correctly.
As an extension, students could work in pairs to create their own inequality jigsaw.

Student misconceptionsStudents often have misconceptions about how to deal with inequalities that involve negatives. When multiplying or dividing both sides of the inequality by a negative number, reverse the direction of the inequality (i.e. > would become <). However, just because there is a negative sign in the inequality does not necessarily mean the direction of the inequality will change. Reinforce to students that it is only when you need to multiply or divide by a negative number, across the inequality, that the direction changes.
Suggested examples1 Find, correct to 2 decimal places, the
value of the unknowns in the diagram below. Then calculate the angle of elevation, correct to the nearest minute, of the top right-hand corner of the box from the bottom left-hand corner.
Answer:
x2 = 5.182 + 8.762
x2 = 103.57x = x = 10.176 934 7…x = 10.18 cm (2 d.p.)
y2 = 10.1772 + 5.162
