Decimal test announcement

Hello,

There will be a Decimal test on Tuesday, April 29th.

A formal review will be distributed within the next few days, but for now, please know how to add and subtract decimals to the thousandths. You should know how to multiply and divide numbers by 10, 100 and 1, 000 (this should only take you a few seconds!), as well as how to multiply and divide any old decimal (this will take you a bit longer).

To multiply decimals, think to yourself "How many numbers are there after the decimal point in my question?" There needs to be that many numbers after the decimal point in your answer! Also, use your common sense to ensure that you answer makes sense. Talking yourself through the problem will often help.

For example:

1.034
x 1.2


You know that your final answer will be really close to 1 (1 multiplied by 1 is 1!), so after you have done the work, check that your answer is logical, and that your answer has 4 numbers after the decimal place (because there are four numbers after the decimal point in total in the question!)

You will all perform brilliantly on this test!
