TESTING CH 2/3/4  ?!

After a few months Werenfridus ...

+ you've learned a lot, I'm sure

+ it might be interesting to know what you still 

   remember from the first 3 chapters!

+ in the following ACTIVITIES you'll find out how much this is.

Ch 2 Solids

ACTIVITY 1a:

+ in pairs

+ tell your neighbour just what you remember from this chapter;

   suppose that (s)he doesn't know anything about it! 

  Try to explain as many fine points about solids as you can.

+ then reverse roles and the listener becomes the talker

+ finally some of you will report shortly to the class how it went.

How did it go?!

ACTIVITY 1b:

+ With the Lollypopsticks a few boys and girls 

    tell the class what they heard from their neighbour in the first turn.

+ Did the 2nd turn - so after you changed the roles- bring anything new?

ACTIVITY 2a:

Ch 3 NUMBERS

+ This time you first Refresh your Memory:

+ OPEN the Textbook on p.72-75, SUMMARY

+ STUDY the summary for 4 minutes

+ You will DO SOMETHING with your knowledge - see the next slide!

ACTIVITY 2b:

Just like ACTIVITY 1:

+ In pairs, 

+ Tell your neighbour what you now know about Ch 3 NUMBERS

+ Assuming (=aannemende) that she doesn't know anything about it yet.

+ Then the roles are reversed (=omgedraaid).

+ Finally some of you will report shortly to the group.

You know ...

On Monday 3rd November 2020, we Math teachers 

had a course on teaching.

We learnt that TESTING is so important, because

you learn so much by it!

The reason is that you get back at the content in an active way.

So....there we go! 

Join the LESSONUP and answer the following QUESTIONS about the older chapters.

How did it go?!

ACTIVITY 2c:

+ With the Lollypopsticks a few boys and girls 

    tell the class what they heard from their neighbour in the FIRST TURN.

+ Did the SECOND TURN bring anything new?

An elevation is ...

1. a solid
2. a side of the solid, that you can see
3. an edge from a solid
4. a cut out from a solid

edges, faces and vertices are ...

1. randen, hoekpunten en zijden
2. zijden, hoekpunten en randen
3. hoekpunten, zijden en randen
4. randen, zijden en hoekpunten

a net is a cut out

1. true
2. false

In a net the same edge appears only once, but a face appears more than once.
(Explanation: next side.)

1. false
2. true

2, 3, 4 and 6 are divisors of 24

1. false
2. true

129 is a .... number.
Fill in the missing word.

explanation:

131 is a prime number, because it can only be divided by 1 and 131 !

is greater than

​8​​7​​

​9​​8​​

1. true
2. false

We have to make the denominators equal, to compare the two fractions:

                  and          =                                               =

Now that we wrote both fractions with denimator 72,

it is clear that         is smaller than           !

​8​​7​​

​9​​8​​

​72​​63​​

​72​​64​​

​8​​7​​

​9​​8​​

=

​125​​75​​

​5​​4​​

1. false
2. true

=              is wrong!  Below you see why!

but not:

​125​​75​​

​125​​75​​=​5​​3​​

​5​​4​​

​5​​4​​

5.6 billion = 5 600 000
(explanation next slide)

1. false
2. true

1 billion = 1 000 000 000

So the English 'billion' is our 'miljard'!

5.6 billion = 5, 600, 000, 000 

 

Choose the right answer:

1. 2/3 = 0.6
2. 2/3 = 0.666
3. both are good
4. neither is good

explanation:

so, the row of sixes never stops!

Here you see the importance of FRACTIONS:

  This is the best notation:

​3​​2​​

​3​​2​​=0.6666666666.....

The x-axis is the vertical axis.

1. true
2. false

A constant graph is horizontal all the time.

1. false
2. true

A line has a beginning and an end.

1. false
2. true

(4, 10) lies to the left of (3, 7)

1. true
2. false

(5, 6) lies higher than (3, 5)

1. true
2. false

A zigzag we use only on the vertical axis.

1. false
2. true
3. it depends

My opinion about this Lessonup is:

1. neither useful nor any fun
2. useful and fun too
3. let's do this again
4. please: never again

Homework time

+ T1 + T2 p.120 from Test Yourself, Ch4 Graphs. 

+ Correct your work with the Solutionsbook

+ Sending in pictures of your work in Google Classroom you do only next 

   lesson. Then you will finish Test Yourself.
