Maths Grade 7

Overview

The Math Syllabus at GEMS Wesgreen International Secondary School aims to support students to develop their ability to calculate fluently, to reason and solve problems through application of knowledge and transferable skills. Throughout the year we recover and extend objectives as the focus is on providing a foundation for understanding the world, the ability to reason mathematically, an appreciation of the beauty and power of mathematics, and a sense of enjoyment and curiosity about the subject.

Learning Outcomes

The aims of all subjects state what a teacher may expect to teach and what a student may expect to experience and learn. These aims suggest how the student may be changed by the learning experience.

The aims of the Math Syllabus are to encourage and enable students to:

  • become fluent in the fundamentals of mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and the ability to recall and apply knowledge rapidly and accurately.
  • reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, justification or proof using mathematical language
  • can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions.

Blended Learning

Throughout this year there will be blended learning and we are using multiple teaching methods in order to help our students learn more effectively. All students whether face to face or learning from home will have the opportunity access all the lessons and resources. This will include a combination of traditional classroom instruction and digital learning, such as:

  • Using wifi microphone to enable remote student to hear more clearly during lessons
  • Using different types of instructional materials
  • Incorporate different means of technology (zoom, teams, phoenix classroom, screencastify)
  • Using their newly acquired knowledge, by applying it in breakout rooms/ or in groups in classroom.

Assessment

Formative: Throughout the units, the children will complete graded work, quizzes and problem solving activities which allows the teacher to assess the students’ attainment and inform their planning.

Summative: At the end of each term we complete internal tests – Unit based and combined Units. Students complete standardized tests such as mid-term tests as well as end of term tests. This allows us to measure the students’ progress throughout the term and year. At the end of the academic year, the students sit for the end of year exams.
