## Introduction

Grade 3 is the class by which the children have realized that school is a part of their routine, so are concepts like homework. More confident than second graders, children in grade 3 are also more expressive about their thoughts and emotions. This is also the age where children influence each other easily. In the meantime, understanding of mathematical concepts becomes even more critical for students. The information provided in this page are identical to the Official Grade Three Math Curriculum  established by the Ministry of Education. ## Overall and Specific Expectations

The overall expectations are divided in five main categories each of which contains several subcategories. Every subcategory lists specific expectations for grade 3 in more detail.

## List of Skills

More than 420 math skills are considered in the math curriculum for grade 3 most of which are common to grade 2. Please, use the detailed list of skills in the old LG for grade 3.

## 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.

1. 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.
2. 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.
3. 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 3:
1. Fractions and mixed numbers
2. Variables and equations
3. Data analysis
4. Transformations

## What We Can Offer

Students have different goals and expectations according to their background, knowledge, or experience. This data along with the result of assessment session help us to design a unique plan for each student. There are different kinds of helps that we offer students in Genius Math:
1. To review and practice their class notes and handouts
2. To be helped with their homework, quizzes, and tests
3. To improve their math skills in general
4. To level up (e.g., moving from B- to B+)
5. To get A+
