3. Which of the following numbers are factors of 80?   2, 3, 4, 5, 6, 8, 9, 10

8. Group these numbers into prime numbers and composite numbers:    59, 93, 97, 87, 73, 45

10. Which numbers from 70 to 80 are prime numbers? 

11. How many dates in September are prime numbers? How many are composite numbers? List them all in each group.

1. Using a Venn diagram, show the factors of 18 and 24, and then the common factors of 18 and 24. 

2. List the common factors of each pair of numbers:

    a) 15, 25      b) 16, 40       c) 18, 42        d) 35, 60

3. Find the factors of each number and put them into a "factor rainbow". 

    a) 48           b) 50            c) 78            d) 62

4. List the factors for each number. Group these factors into prime numbers and composite numbers.

    a) 34           b) 40            c) 72            d) 94

5. Make a "factor tree" to find the prime factors of each number.

    a) 64           b) 85            c) 90            d) 76

8. Fill in the "factor trees" with a combination of numbers that works. 

 

I suspect these last 2 questions will be the most challenging, but we have practiced questions like the others a lot in class so the rest should be straight forward.

In math class we are focusing on the following math terms currently: multiples, common multiples, factors, common factors, prime numbers, and composite numbers. Any extra practice at home to help the students get a strong grasp of these concepts would be great. 

As I mentioned on the Facebook page yesterday, practicing skip counting and multiplying help to make questions involving multiples and factors respectively much easier and quicker to solve. 

In French, the terms are: multiples, multiples communs, facteurs, facteurs communs, nombres premiers, nombres composés

5. List the first 3 commun multiples of each pair of numbers.

6. List the first 3 commun multiples of each group of numbers. 

7. List all the commun multiples of 8 and 9 up to 100. 

Bonus: #4. Which number has 21, 24, 45, 30, 42, 60, and 84 as multiples? 

a) 3      b) 12       c) 7       d) 15

Currently we have been working on interchanging between standard form (forme symbolique), expanded form (forme dévéloppée), and written form (forme en lettres) with large numbers in the millions (millions), billions (milliards), and trillions (billions). 

**The French terminology is in brackets. 

If you would like to practice with your child at home, here is an example to help: 

Expanded Form (Forme Dévéloppée): 30 000 000 000 + 4 000 000 000 + 900 000 000 + 3 000 000 + 100 000 + 50 000 + 600 + 40 + 8

What is the standard form (forme symbolique) and written form (forme en lettres) of this number?? ^^

Answers:

Standard Form (Forme Symbolique): 34 903 150 648

Written Form (Forme en Lettres): thirty-four billion nine hundred three million one hundred fifty thousand six hundred forty-eight 

(trente-quatre milliards neuf cent trois millions cent cinquante mille six cent quarante-huit)

**Be sure to emphasize how the amount of zeroes in a number in expanded form helps to determine place value in standard form.

We had some fun as a warm-up today with this cooperative team version of “rock paper scissors”. The students loved this game and enjoyed an active twist on a classic!
