Negative number tales

I would like you to write a Math Tale. What is that? These are short stories with a problem to solve. What I suggest you to do is to write a funny math story with a simple problem to solve about negatives. Use negative numbers and negative situations (ex. Temperatures below zero, loans, money, debts, lifts…). Work in pairs. Include your names and stories as a comment, and, of course, solve your problem!

You can see more examples in http://mathtales.ca/stories.html
And here you have a useful dictionary
You can start with: ONCE UPON A TIME... or LONG TIME AGO...

Below zero: bajo cero
Loan: préstamo
Credit: crédito
Steal, rob: robar
Lose: perder
Debt: deuda
Go down, decrease: bajar, descender
Go up, increase: subir, aumentar
Climb: escalar
Peak: cima, pico
lift: ascensor

basement: sótano

 Enjoy it!



Hello boys and girls!

I know that you are very excited about our next work, but be calm! First of all, you have to make a group (four members, maximun), choose the Roman period and let me know it by sendind an e-mail to arcihistoria@gmail.com.

After that, you have to organize your work: making a general outline about your Power Point (topics, number of slides...), dividing the tasks among the members, decide the appearance of your work (colours, letters, sizes, images...), etc.

At the same time, take into account those items that I´m going to evaluate. Don´t forget anyone! You can see them by clicking on this link.

Evaluation rubric

Here you can find information about each period of Roman History:

One last thing. Remember: the better a Power Point is, the clearer the contents are. So, please, don´t copy-paste never-ending paragraphs, because nobody is going to read them. Your Power must be appealing, clear and original.

Good luck!


Negative numbers (I. Whole numbers, number line)

Hello boys and girls,

now that the weather is getting colder, it is the best time of the year to study NEGATIVE NUMBERS :-)

These are part of a bigger group, called Whole Numbers.

To study them, the number line is very useful; it may help you to tell which numbers are bigger or smaller. Read about number line by clicking here (remember to solve the six questions down). After that, play this game for a while to see if you really understood...

At the end of the class, if you feel comfortable with number line and operations on it, try with this game, with more difficult movements... Play

Good luck,
