Grade 8:
Week of February 23:
Grade 8s will be putting the finishing touches on our multiplying and dividing of mixed numbers. That means we will have a cumulative quiz during the week.
Our next area of study will the relationship between fractions, decimals and percentages. This will serve as the foundation for problem solving over the next few weeks, especially with fractions and percentages.
Week of February 17:
Grade 8s are going back to the beginning of the year...spending time with fractions. It is no secret that the more we review concepts, the better we know them. So this is a chance to gain a better grasp on fractions. But this time, we are introducing mixed numbers. Our time will be spent multiplying and dividing.

This week, the grade 8s are applying the Pythagorean Theorem to problem based situations. This concept is very useful in the world of construction, interior design, roofing, etc.

Week of January 19:
Now that the grade 8s have wrapped up their work with square roots, they will begin to apply a square root to a more practical concept: the Pythagorean Theorem. We will finding the length of a missing side of a right triangle.

Week of January 5:
Grade 8s have returned from their winter break to work with perfect squares and square roots. This is very much a new topic for them. Having a good knowledge of their multiplication would be useful. Square roots are crucial for being able to use the Pythagorean Theorem. This is the concept that we will be moving in to once we are done our work with squares and square roots.

Week of December 8th:
Grade 8s have begun to move into solving two step equations. Last year, they were exposed to solving single-step equations. It is very important that they show their thinking steps as the equations will become much more difficult next year so it is easy to get lost in the work; get in the habit now.

Week of November 18: Grade 8s are finishing up their work with multiplication of fractions, if they haven't already. The last of our classes will be completing an addition, subtraction and multiplication of fractions quiz.
The next step will be moving into division of fractions. Students will see this first using models pictorially followed by more traditional methods, like using the reciprocal.
Week of November 3:
Grade 8s have begun to multiply fractions this week. We started by introducing this concept using the area model. Students then start to see that they can multiply symbolically without the use of a picture.

Week of September 15:
Much of our week will be spent completing the Number and Algebra Assessment. This is used to gauge where students are at with their abilities, whether they are below grade level or at grade level.
Grade 8s will also be starting with integer division.
Week of Sept 8:
After reviewing some addition and subtraction of integers, we will be getting into the grade 8 program by working integer multiplication. Expect a quiz by the end of the week.
