Middle School Math – March 2018

The change in curriculum to use Eureka Math has been going well.  The program is inquiry based and has provided the students with lots of opportunities to explore, practice, challenge, prove, and discuss various mathematical concept.  I have learned a lot myself.

In Course 1 we are finishing up our understanding of the four operations as they study division of whole numbers, division by a fraction and operations on multi-digit decimals.  This expanded understanding serves to complete their study of the four operations with positive rational numbers.  As we move forward, we will be working with negative rational numbers; focusing on understanding, locating, and ordering negatives numbers.

Course 2 is also completing a unit.  We have been exploring operations with signed rational numbers, in other words, adding, subtracting, multiplying and dividing positive and negative whole and rational numbers.  Next, we will be using these skills to evaluate expressions and solving equations and inequalities.

At the end of February Course 3 completed a unit that students learn about dilation and similarity and apply that knowledge to a proof of the Pythagorean Theorem based on the Angle-Angle criterion for similar triangles.  The unit begins with the definition of dilation, properties of dilations, and compositions of dilations.  As March begins students extend what they already know about unit rates and proportional relationships to linear equations and their graphs.  Students understand the connections between proportional relationships, lines, and linear equations in this unit.

And, in Algebra we have explored properties of exponents and polynomials, learning how to add, subtract, and multiply various polynomials to prepare us for our current unit on factoring polynomials:  from factoring a GCF of an algebraic expression to factoring a trinomial into the product of two binomials.  Learning how to factor quadratic trinomial prepares the students to be able to solve quadratic equations (our next unit).  It’s all good fun!
