Storytelling in the IM K-5 Math Curriculum

Kristin Gray, Director of K–5 Curriculum & Professional Learning

Curriculum

An excellent mathematics program includes a curriculum that develops important mathematics along coherent learning progressions and develops connections among areas of mathematical study and between mathematics and the real world.

Principles to Action by National Council of Teachers of Mathematics


Developing coherent learning progressions and connections among areas of study requires crafting lessons to tell a mathematical story. Lessons must coherently build across units and grade levels and attend to many things: the mathematics, representations, activity structures, and learning trajectories, to name only a few. Each of these considerations impact how students access the mathematics and influence the belief that mathematics is a connected set of ideas that makes sense.

Truth and Consequences Revisited

By William McCallum

What are extraneous solutions?

A while ago I wrote a blog post about solving equations where I talked about seeing the steps in solving equations as logical deductions. Thus the steps
\begin{align*}3x + 2 &= 5\\3x &= 3\\x &= 1\\ \end{align*}

are best thought of as a sequence of if-then statements: If $x$ is a number such that $3x + 2 = 5$, then $3x = 3$; if $3x = 3$, then $x = 1$. Continue reading “Truth and Consequences Revisited”

IM Preparing for the School Year

There are always so many things to do in preparation for a new school year.  At this point of the summer, to-do lists start getting made, materials get purchased, rooms are organized, and math class planning begins. Whether you are using the IM 6–8 Math curriculum for the first time or entering your second or third year with the program, there are always new things to learn. While the Illustrative Mathematics blog is packed with great information from curriculum authors, teachers, and coaches, it can often be a job in and of itself to narrow down what to read.
