Studying For Your Fractions Summative?

Math 6 students: your fractions summative assessment is this coming Monday!  Make sure you study carefully in order to do well on your test.

The test will cover all operations (addition, subtraction, multiplication, and division).

There will be questions that are computations (calculate 1/2 x 3/4) and questions that are word problems.  Many questions will ask you to explain your answers in words and draw models (pictures).

How can I revise?

• Review slide sets.  These are linked on each day in the homework calendar.
• Study your operations graphic organizer that we completed in class.  If you completed this well, it will show you the steps and models for all of the operations.
• Check out the Unit Resources page for specific practice on each topic.

If you are struggling with modeling, please watch this video that I recorded.  It walks you through the Check Ups on multiplication and division.

Good luck!!!
