Morphology Investigation 3

You will review previous lessons in the module and begin to think about posi:ve and nega:ve integers.

You will learn more about how to find the most meaningful parts of words.

In this ac:vity, you will get up out of your seat and embody posi:ve and nega:ve numbers. By playing the role of posi:ve or nega:ve, this game will teach you how posi:ve and nega:ve numbers affect each other. In this ac:vity, you will prac:ce adding and subtrac:ng posi:ve and nega:ve numbers. You will learn other characteris:cs of posi:ve and nega:ve numbers through a true/false ac:vity.

1. If you borrowed six dollars from Steve for some pizza, two dollars from Angelo for a soda, and three dollars from Michelle for a cookie, how much money will you owe in total? 2. Is there a math sign you can use to show that this is money owed, not money you actually have?

This ac:vity will help you to iden:fy the most meaningful parts of words. This will deepen your understanding of a word and its related forms.

READ, LOOK UP, DISCUSS

1. In your group, look at and read your words. Discuss what they might mean. Think of everything you already know about the words.

2. Use the etymology, word-‐root dic:onaries, and any other sources you want in order to figure out the morphemes that make up this word.

3. Figure out what each morpheme means.

4.  See if you can find other words that contain some of the same morphemes.

5.  Figure out the history of each morpheme.

What language does it come from? Has it always meant the same thing? What other words have this morpheme?

6.  Discuss how the morphemes word together to create the meaning of the word. Can the morphemes help you remember how to spell the word?

7.  Present one of your words to the class.

What is a word? What are the

different parts of a word?

How are words formed in different languages?

How can knowing word parts help us

to learn new words?

How can it help us to deepen our understanding of

words we already knew?

WATCH & DESCRIBE

1.  You will now watch two videos rela:ng to posi:ve and nega:ve integers.

2.  When you are done, think of and describe at least one addi:onal example of where you see nega:ve numbers in your life.

MOCK BATTLE

1.  You will be par:cipa:ng in the "Ba^le of posi:ve vs. nega:ve.”

2.  Your teacher will first model the ac:vity and then you will work on the problems together as a whole class before branching off to do individual work.

b)  Determine whether each statement is true or false and explain why.

i.  The sum of two posi:ve integers is always posi:ve.

ii.  The sum of two nega:ve integers is always posi:ve.

iii.  The sum of a nega:ve integer and a posi:ve integer is always nega:ve.

iv.  The sum of a nega:ve integer and a posi:ve integer is always posi:ve.

Where did the pa^erns you found fit with the statements and where

did they contradict them?

Did you think differently when you had to answer ques:ons in words, as

opposed to just using numbers and math symbols? If so, how?

REFLECTION ON THE MATH

Your teacher will give you a link to wall wisher for the following ques:ons. Be prepared to share out your thoughts.

1.  Now that we have calculators readily accessible to us, explain why it is valuable to know how to manually add and subtract nega:ve and posi:ve integers?
