Patterns & Coordinate Graphing

We are finishing up our patterns and coordinate graphing unit!  My kids had so much fun with this one, especially coming up with their own patterns.  They love to really push it and think outside the box when creating their patterns.

We began the unit with patterns.  We did both shape and number patterns--all kinds of patterns.  On the more complicated number patterns that have alternating rules or less than obvious patterns, I teach kids to use a bridge underneath each number to recognize what is happening.  They look at it in all directions-- are they adding, subtracting, multiplying, or dividing each number?  Then they learn to look at the pattern within the bridges.  I have seen year after year that kids use the bridges on their work, especially on state testing.

You can see an example of the bridge under a few of the number examples on our Patterns & Functions Anchor Chart.  Some close ups on the anchor chart below...

We used a differentiated packet that I created to practice patterning (I'm silly and left the pictures at school, so I will have to add those tomorrow).  We did all kinds of practice, and the kids actually wanted MORE.  We also had a set of patterns and functions task cards that we used to practice.

After I felt like they had mastered this, I moved on to coordinate graphing, which was a breeze for my students.  They copied the anchor chart in their math journal and then did a proof.  We practiced with a bunch of function tables.  We created coordinate graph pictures of our own and worked through a few story problems.  This only took a day or two and they were solid!
