ALGEBRAIC NOTATION: MATHS AS A FOREIGN LANGUAGE YEAR 9 (COMPETENCIES: NUMERACY & CRITICAL THINKING) AUSTRALIAN CURRICULUM LEARNING OBJECTIVES • • ACMNA232:1 solving a wide range of linear equations, including those involving one or two simple algebraic fractions, and checking solutions by substitution. ACMNA177:2 identifying order of operations in contextualised problems, preserving the order by inserting brackets in numerical expressions, then recognising how order is preserved by convention. RESOURCES REQUIRED • • • • Algebraic Notation: Maths as a Foreign Language3, streamed online with projection facilities (33 minutes). Algebra video worksheet4 x class set Algebra challenge worksheets5 x class set Algebra challenge answers6 x class set LESSON OUTCOME: students investigate key theories in algebra and apply their skills to algebra to the real world Lesson outline: 1. 2. 3. 4. 5. 6. Students draw in the equation gaps on what makes them happy: …….. +……………+…….. = happy. Introduce algebra as a similar concept but using letters as part of mathematical notation they will become more familiar with in high school Hand out video worksheets and introduce video. Students fill out worksheet as they watch Review answers from video and clarify questions Hand out algebra challenge worksheets to students to complete. Go through answers and introduce homework/extension activity HOMEWORK/EXTENSION Students compose their own mathematical story like the narrator does using her bike analogy in narrative form OPPORTUNITY FOR FURTHER ACTIVITY Interactive algebra activities can be completed from Cut the Knot website. 1 http://www.australiancurriculum.edu.au/Search?q=algebra http://www.australiancurriculum.edu.au/Search?q=algebra 3 http://webplayer.clickview.com.au/?p=bRut 4 http://www.capthat.com.au/sites/www.capthat.com.au/files/Algebraic%20Notation%20worksheet.docx 5 http://math.about.com/library/prealg1.pdf 6 http://math.about.com/library/prealg1s.pdf 2 1
