Make Your Own "Weather" Map
Students develop and apply a variety of strategies to solve problems, with an emphasis on multi-step and non-routine problems. They acquire confidence in using mathematics meaningfully.
Curated OER
Angles in Art
Students utilize their handheld and the Angles program to create a non-objective artwork. Images created by famous artists who have utilized angles in their art work are examined.
Curated OER
Composition of Reflections
Learners perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

Graphing Data Brings Understanding
Students collect, graph and analyze data. In this statistics lesson, students use circle, pie, bar and lines to represent data. They analyze the data and make predictions bases on the scatter plots created.
Curated OER
Make Your Own "Weather" Map
Pupils create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar map.
