Hello Grade 7's,
Great to see you are visiting the blog. As we continue to move through our mathematics curriculum and wrap up or fractions unit, we will soon be jumping head first into the geometry unit. Hey, I heard that, stop groaning, just kidding. Geometry can at times be challenging, however like all other subjects we will try our best and have fun while developing our learning. As you have experienced through my time with you all, I am a great believer in the use of dynamic software in which students can use hands on activities and games to aid in their own learning process. Keeping with this belief I have provided a link to some dynamic geometry software that will help you to explore the geometric concept of dilations (enlarging and reducing the size of an object). Please try this activity to explore this concept further. You will notice that you can clear the objects on the screen by simply pressing the clear button. From this point you can create your own shapes and patterns and continue to explore dilations by using the patterns you have created. Points you may want to think about may include:
1) What must I do to a shape and its original measurements to shrink it?
2) What must I do to a shape and its original measurements to enlarge it?
3) Can I describe dilations in my own words?
4) How might an artist or architect use dilations to construct works of art?
*The above mentioned activity will assist you in building understanding of dilations in preparation for our geometry unit.
*The activity is also designed to address the specific expectation of identifying, performing, and describing dilations through investigation using a variety of tools (i.e. dynamic geometry software). This specific expectation is an expectation that lies within the Geometry and Spatial Sense of the Grade 7 Mathematics Curriculum.
*As an further review activity you may want to view the Alphabet Geometry videos, these should give you a quick review on the many transformations involved in the geometry unit.
