Today's estimation was a second industrial hose. This coming after seeing a 50 foot garden hose compared to the same let the industrial hose. I loved hearing the talks of how to do one and a half times 50 feet.
Since there was a rally 2-3 and we were on a Wednesday schedule short periods I explicitly told students what I wants them to investigate. We discussed switching m and b in y equals my plus b.
Then students observed a graph with a negative slope and a line ordered that was a positive slope. Student explanations were great.
Thirdly I wanted students to graph 2x-8 and explain how to do so without a table.
Lastly students solved for y in multiple ways and graphed it. We saw how one method is more efficient than another when solving for y in 2x-y=4.
Students were assessed on a point on a figure that was transformed, scale factor, and a scatter plot.
|Here you can see their learning goal and success criteria. This student added y to both sides, then subtracted 4 from both sides.|
|In this class they subtracted 2x from both sides then multiplied both sides by -1.|
|Here we had a mini number talk on the multiply ways to multiply 1 and a half times 50.|
|On Monday we will review this method, and also take notes on vocabulary for fractional exponents because half the class is confused about it.|
