# Grade Seven Math Curriculum

# Grade Seven Math Curriculum

## Introduction

Beginning of Intermediate School and on the brink of their teenage years, Grade 7 helps children discover their true personality. This is also the year in which academic competition starts to rise and directions towards future careers begin to be mapped. Strengthening of mathematical concepts in this grade also becomes imperative. Moving from the world of basic decimals and fractions, Grade 7 further explores the number system and proportional relationships and introduces the concepts of transformations and congruence.

## List of Skills

More than 340 math skills are considered in the math curriculum for grade 7 many of which are common to grade 6. Please, use the detailed list of skills in the old LG for grade 7.

## Evaluation

Objective evaluation is believed to be one of the most essential parts of teaching mathematics. In Genius Math, we use different tools and methods to evaluate the mathematical knowledge of students and their progress. Our evaluation process consists of three stages: before teaching sessions, during teaching sessions and after teaching sessions.

**Initial Assessment Test**

Before starting our teaching sessions, we administrate an assessment test to obtain some insights on the strengths and weaknesses of students and their previous math knowledge. This key information helps us to come up with a special plan for every single student.**Standard Problems**

During teaching sessions, we use a combination of different resources providing standard problems that are designed by famous mathematicians all over the world to improve the problem-solving skills of students. Among those resources are Math Kangaroo Contests, CEMC (University of Waterloo), AMC (American Mathematics Competitions), and even IMO (International Mathematics Olympiad), the latter might be considered for those who want to tackle more challenging problems or prepare for math olympiads. We use these problems to design homework, quizzes, and tests for our students based on their grades, needs and goals. As a matter of fact, such problems can be used to unveil the depth of students’ mathematical understanding.**Final Assessment Test**When teaching sessions are over, students are asked to take another assessment test aiming to show their real progress in mathematics.

## Most Common Challenging Topics

The followings are among the most common challenges students face in grade 7:

- Fractions and decimals
- Mixed operations
