Planning a good strategy
Grade 10s are working on problem solving, especially planning a good strategy.
We looked at how to decipher a problem to pull out important aspects that are hints for what strategies we may need.
We talked through some of the homework questions that had been challenging, and we also learned a new fact about quadrilaterals. If you join the midpoints of each side, the interior quadrilateral that is formed is always a parallelogram).
We calculated slopes and classified that the central shape is a parallelogram, and then we verified that it will always be the case by making a dynamic model with desmos geometry. We can measure angles and side lengths, and then adjust the drawing and see what happens to the side lengths and angles.
