Comparing Fractions with LCD and Earthquakes

Announcements:

• Sign up for Parent-Teacher Interviews - Interviews are Thursday, December 6th 
• Sexual Health is being taught by guests from the Sexual Health Centre for 7-4 this week

Math:

This week we are focussing on:

Comparing fractions with area models and using the lowest common denominator (LCD)

Ordering fractions from least to greatest 

Adding and Subtracting Fractions with Like and Unlike Denominators using models and various methods of determining the LCD

Science:

This week we continue to study Sudden Earth Events. We watched Bill Nye Earthquakes Video to introduce concepts related to earthquakes and finished plotting coordinates of earthquakes and volcanoes on our Pacific Rim maps.

We also reviewed the parts of a circle and learned to use compasses so that we could triangulate the epicenter of earthquakes. See attached "Finding the Epicenter" assignment.

Both the Mapping assignment and the Finding the Epicenter assignment had cross-curicular outcomes with Mathematics.

Extra Practice:

• There are worksheets for all of the concepts covered in the Fractions Unit available for students to take for extra practice in my classroom
• Students can visit Khan Academy (for example they could search visually adding and subtracting fractions) and type in a topic of their choice for extra practice
• The two most recent Science assignments are linked to this blog entry
