During today’s Math class we spent some time talking about simplifying expressions by collecting like terms. Afterwards we used playing cards in a group activity that brought collecting like terms to life.

If you need the handouts, all 3 levels are here:

Today during Math time we reviewed some mental math – adding, subtracting, multiplying, and fraction reducing – and introduced our visiting grade 6 students to ‘Amoeba Math’ at the same time.

Now, the plan is to spend some time upgrading the portfolio sections of our binders to show what has been learned. Make sure you have excellent examples of the following items in your portfolio:

*fractions (add/sub/mult/div)

*order of operations

*venn diagrams

*exponents

*integers

Today in Math we reviewed/learned the concept of ratio and what it means.

We applied our knowledge of ratios to figure out distances on a variety of maps. This ties in with our Humanities this Quarter: British North America and Nouvelle France.

Here’s a video example of using a ratio to find distances on a map:

Today we did a super quick review of the multiplication of integers before we played a game using multiplication of integers and finished up with our Distributive Property work.

If you are interested in further explanation of why a negative times a positive gives you a negative number, Khan Academy has a really good explanation:

You could also watch videos of adding and subtracting integers, if you want to review further back:
