Magnetic Decimal Place Value Arrows

1 06 2018

I saw these being used yesterday. I wondered how many different ways they could be used?

My immediate thought was order of decimals and the significance of the different place value positions. I then thought of ways to pictorially represent additions and subtractions.

How about issuing half a dozen combinations (1,2 or 3 digits) to students and asking them to stand in the corresponding order of the number line, at the front of the class? How about then trying to stand apart to reflect the order of size of the combination they were holding?

What about placing different 3 digit decimals on a desk and asking each member of the group to come up with a problem with that as the answer or even a problem using that number as one of the components. Follow this with table and or class discussion and fully written individual solutions etc. Access to whiteboards or paper could help the discussions for these activities.

Questions which may be asked during the learning session could be:

Why do we normally write a zero before the decimal point if there isn’t a non-zero digit there? Why isn’t there a zero at the end of the magnet?

What questions would you ask?

Students could even make a set from paper or cardboard and build a game from their tiles.

Company Tax Rates Versus Personal Tax Rates

28 04 2018

This article prompted me to investigate current company tax rates. They’re currently 27.5-30% without a tax free threshold.

I then investigated personal income tax rates. A person earning $37000 and hence at the bottom of the 19% bracket pays 9.7% of each dollar earned.

A person earning $87000 and hence at the bottom of the 37% bracket pays 22.8% of each dollar earned.

A person earning $180000 and hence at the bottom of the 45% bracket pays 30% of each dollar earned. I was not able to find what proportion of tax payers this would be.

I then went in search of past personal tax rates because I could recall the top bracket being 66.7%.

This is what I found for the 1971-72 financial year.
