Math 6_February 12

Today we continued making progress towards our learning target:

I can calculate the area and circumference of circles.

We did this through analyzing mistakes:

And by practicing with word problems.

here is a good explanation

Math 8_February 10

Today in class we discussed Set Relationships

Here are our class notes: (my phone doesn’t want to upload photos…)

Definition- Mutually exclusive: Contradictory; Both cannot be true at the same time.

Example: when flipping a coin, it cannot land on heads and tails at the same time.

Mutually Exclusive events are represented by “Disjoint” Venn Diagram Circles (they do not overlap).

 

Thus P(A and B) = 0.

 

Here is a website with a great walk-through of the concept

Here is a short clip with another explanation

Homework (pg 3): SetRelationships

Math 6_February 6

Today we worked on finding the area of composite (compound) shapes.

We had to know how to find the area of parallelograms (base x height) and how to find the area of triangles (base x height divide by 2).

Hopefully those help a bit.

Our homework due Friday: Covering and Surrounding pg 67 #39
