Sometimes dividing large numbers can be hard, but the repeated subtraction method is a lot easier to understand and this was you can apply your previous subtraction skills! In the future, if you find yourself stuck on a division problem, solve it by repeated subtraction!
Roman Numerals are very important to history and modern day items, such as grandfather clocks, pages, and other ways to number things! Just remember to always know when a Roman Numeral is being used, because later in math, you'll see different variables as letters!

Get with a friend, sibling, parent, etc. Set up three of your own division problems (in Roman numerals) and see if they can identify the numbers and solve the problem! On the back of your homework, write down your problems and answers, and be ready to discuss them in class!

Here are two websites that you can use to learn a little more about Roman Numerals and why they are still important!

After reading these, consider this: How do you think our number system (1,2,3,4..) be different if we did not have a 0? Write your thoughts at the bottom of your paper and we will share them in class.

Now that you have worked on Roman numerals, repeated subtraction, and long division, let's put your skills to the test!
There are 60 minutes within 1 hour. I want you to find how many times 15 minutes go into 1 hour. Try to only use Roman Numerals to repeatedly subtract and find your answer!

We're going to twist up our fun activity with some ancient numbers! The Roman's are notorious for their togas and gold-leaf crowns, but what about numbers? You probably have seen these before, but this time, you get to learn how to read, write, and solve long division and repeated subtraction problems with Roman numerals. I have placed some pictures on the page for some help,

Repeated Subtraction is another way to find the answer to your division problem. Sometimes, we deal with larger numbers being divided by large numbers. Here is how you would perform repeated subtraction:

Today is a fun day, a great day!
Our assignment will be solving Long Division with the use of Repeated Subtraction, which will include a fun history lesson about the Ancient Romans! Earlier this week, we played around with some division problems, but now we're going to step it up! I provided all of the materials you will need to complete your assignment, including examples, explanations, and of course your assignment!
Have fun dividing!
