You can view the Fundamentals of Math video series on YouTube. Check out each video to help think through ways to teach complex math concepts in your classroom.

Working With Numbers – Magnitude

In this , we will look at working with numbers and in particular, the magnitude of whole numbers.

Working With Numbers – Place Value

​In this , we will build on our understanding of magnitude of number and extend our thinking to the importance of place value.​

Working With Numbers – Fraction Models

​In this , we will dive deeper into fractional quantities and unpack some of the many math models that help us make fractions more accessible for all learners.

Why The Unit Of Measure Matters

In this , we will begin diving into recognizing and applying our understanding of number properties.

Relating Fractions, Decimals and Percentages

​In this , we will spend some time unpacking how fractions, decimals, and percentages are related.

Mastering Math Facts – Addition

In this , we will tackle the first operation students encounter and at an early age – addition. In particular, we'll explore addition structures or types of addition as well as important properties of addition.

Mastering Math Facts – Subtraction

In this , we'll move on from addition to the first operation that can often challenge many learners – subtraction. Similar to addition, subtraction also has two structures or ways we can think about subtraction scenarios.

Related Addition and Subtraction

​In this , we will extend our learning from addition and subtraction structures and dive deeper into more complex addition and subtraction scenarios to reveal how these operations are related.

Mastering Math Facts – Multiplication

In this , we will extend our learning from addition and apply it to multiplicative scenarios using context and mathematical models.

Mastering Math Facts – Division

In this we will turn our focus to what is easily the most challenging elementary operation of all – division.

Developing Proficiency with Operations – Integers

Now that we have explored some of the important conceptual understandings in order to help our students build automaticity around addition, subtraction, multiplication and division, let us extend our learning from positive whole and fractional quantities to integers in this .

Developing Proficiency With Operations – Fractions

In this we will dive into operating with fractions to see how mathematical models and focusing on the unit of measure can help us navigate this often unclear area of math.
