Summer Math Tips

NEW! We're delighted to introduce Summer Math Tips: A Guide for Families—a valuable resource designed to help families combat the "summer slide" and keep their children engaged in math over the summer.

This guide offers practical tips and strategies that integrate math into everyday life, helping children maintain and enhance their math competency. By incorporating these tips, families can boost their children's confidence, perseverance, and enthusiasm for math, ensuring they are ready and excited for learning in the new school year. These tips will nurture a love of learning, deepen understanding, and strengthen abilities to use mathematical thinking both in and out of school.





Critical Thinking in Math: A Focus on Mathematical Reasoning Competencies

Critical Thinking in Math

TC²’s approach to math embraces the idea that sustained quality mathematical thinking, or reasoning, is the key to the success of current and future generations of math students.


What Is Mathematical Reasoning?

A mathematical reasoning approach optimizes the learning opportunities for every student in the classroom. It empowers students with the capacity to independently detect the need for, and to use, a wide range of math reasoning abilities.

This approach ensures that students develop both

  1. a strong understanding of foundational math concepts and content, and
  2. the capacity to reason soundly about and with these concepts and content.
When we focus on reasoning competencies, students continue to learn important math concepts while also learning how to
  • deeply understand
  • appropriately act on, and
  • effectively communicate using those concepts.

What Are Mathematical Reasoning Competencies?

Eight key mathematical reasoning competencies underpin all math learning and are needed for student success in math. These are presented in A Math Pedagogy Designed to Empower Learners [PDF].


Competency Definition

Core competencies

Sound thinking or reasoning

Reasoning about the quality of one’s thinking

Reflective reasoning

Reasoning about the quality of one’s understanding, actions, and communication

Understanding

Conceptual reasoning

Reasoning about what makes a concept what it is and how to recognize that concept

Detail-minded reasoning

Reasoning about which mathematical details to use and how to use them effectively

Acting

Connective reasoning

Reasoning about how to effectively connect ideas

Problem-managing reasoning

Reasoning about how to effectively identify and solve math problems (including how to effectively select, organize, and use mathematical strategies, tools, and resources)

Communicating

Representational reasoning

Reasoning about how to effectively represent ideas

Language reasoning

Reasoning about how to effectively use the language of mathematics including its structure and symbols




"To provide each and every student equitable opportunities to improve their learning success in math, students need to learn how to reason soundly in a variety of ways through the application of critical thinking.

Describing Trends in Data: Which data set should be considered linear in the trends it presents?
In this lesson, students learn how to use lines (curves) of best fit to help them effectively describe mathematical trends in data. Most suitable for grades 8–10.


Intermediate (7–9)

Grade 9 Student Lessons
These lessons were developed in partnership with the Matawa Education and Care Centre.

What is the best way to represent information to help you make financial decisions: a table or a graph? [PDF]
In this lesson, students compare different ways of organizing information to create a budget that will help them make the best financial decision.

Which best describes the trend in the data: a line of best fit or a curve of best fit? [PDF]
In this lesson, students consider different patterns in the data that describes the relationship between fish and seafood consumption and the year. They then make the most accurate prediction about fish and seafood consumption for the year 2030.

How well does an equation match a line of best fit, a table, and a description in words? [PDF]
In this lesson, students explain how well an equation given to them describes the line of best fit and the trend in the data. They then use the equation to make a prediction.

NEW! Assessing Mathematical Thinking: A Focus on Reasoning Competencies
This new title in our Quick Guides to Thinking Classrooms series presents a framework for effectively assessing and evaluating thinking in math. It shows how building math assessment practices on a foundation of essential mathematical reasoning competencies provides a clearly defined, manageable, and consistent way to focus assessments.

A Math Pedagogy Designed to Empower Learners [PDF]
Laura Gini-Newman outlines a new pedagogical approach to the teaching and learning of mathematics that is focused on building student capacity to reason mathematically through critical inquiry.

Critical Inquiry in Math Class
During TC²’s 25th Anniversary celebration, each month explored a different focus. April focussed on how we can bring critical thinking into math. This webpage introduces the focus and explores ways to enrich your classroom with critical inquiry in math.
