This week I taught a mini-unit on coordinate grids as a supplement to their regular math lessons. They need to know this concept for the PSSA's, but it will not be covered until afterward. My CM helped me a lot with finding resources on the topic. I used an old version of the Investigations curriculum that taught coordinate grids by looking at a neighborhood map on a grid system. I started the unit by introducing the concept through the PSSA Coach book. Then we used the Investigations curriculum to explore the ideas further. We ended with a computer game about ordered pairs. I really enjoyed having this continuity throughout the week and delving further into a particular topic. Previously I have just been teaching mini-lessons in math from the PSSA coach book, so it was a nice change of pace. It has made me excited to teach the upcoming math unit on graphing that I will start in 2 weeks.
