With our biodiversity project underway, it's time to pay some attention to what has been going on in math. At the start of this year, we have been reviewing integers as a vehicle to our first unit on rational numbers. With that in mind, at the end of our first week we did a pre-assessment on addition, subtraction, multiplication, and division of positive and negative numbers that are whole or fractions. The interesting component to our course this year is the addition of a new section to the grade 9 mathematics PAT. This section, designed to emphasize mental mathematics, will highlight the importance of numeracy beyond technology. At the bottom of this post, I have posted an excerpt from the Alberta Government regarding the mathematics PAT. What are we doing this week?This week is seeing the start of our rational numbers unit. Because of this, we are going over positives and negatives, fractions and number lines, and decimals. I am a big advocate of working within your comfort zone and since students usually have a preference in terms of working with fractions or decimals, being able to convert between them is essential. With that in mind, if you are wondering what can be done to supplement the course at home, working on conversions and then adding, subtracting, multiplying, or dividing the converted numbers before converting them back is a great exercise. As an example: Additionally, below is a copy of the workbook for rational numbers. We will be utilizing some of the exercises in class but doing them before hand is fine as we can always supplement lessons with additional or alternative questions.
