Number of the Day

1. Divide the number by two.

2. Expanded Form. (Eg. 1000+200+30+4+0.5+0.06+0.007+1234.567

3.Write the number in words. (Eg. One thousand, two hundred, thirty-four and five hundred sixty-seven thousandths)

4.Round to the nearest hundred. (01234 the hundred stays, 56789 it goes up)

5.What digit is in the tenths place. (For this, it's important to know your place value

6. Double the number. (x2)

7. Find the Circumference. (use the formula: C=2(pi)r)

8. Make a power. ( n*: n is the base, the star is the exponent)

9. Make the power in factored form (the power you did for #8). (Eg. 4x4x4x4x4=1240)

10. Cube the in the ones place. (n*: n is the digit in the ones place, the star is the exponent for cube)

11. Square the in the hundreds place. (n*: n is the digit in the hundreds place, the star is the exponent for squared)

12. Use calculator and round to the nearest hundredth.

13. The product of all the digit. (1x2x3x4x5x6x7=5040. If there is a zero in the number the product is 0)

14. Prime Numbers in the Number of the Day. (Numbers with 2 factors, one and its self)

15. Find the area. (Use the formula: A=(pi)r(squared))

16. Use the divisibility rules.

17. Find the prime factors.

18. Use integer notes.

19. Use subtracting integer notes.

20. Create a fraction.

21. Create an improper fraction.

22. Create a mixed fraction.

23. Convert into a decimal.

24. Create a picture for #21.

25.Convert answer to #21 into a percent.

Divisiblility Rules

Today in class we talked about different kinds of diagram.

Carroll Diagram- is a table used to show how numbers are the same and different

Example



Use Carroll Diagram to sort 30, 79, 162, 3996, 23517, 31974



A Venn Diagram shows relationships between groups of numbers

Example


Use Venn Diagram to sort 93, 540, 955, 8060, 67982, 84430


Common Factor

A number that two or more numbers are divisible by


Example: 4 is a common factor of 8 and 12


Find the factor of 24


Find the factor of 32


Find the common factor of 24 and 32


Find the greatest common factor

The common factors are 1, 2, 4, and 8.


The greatest common factor is 8.


Homework:


Find the factors of 18


Find the factors of 30


Find the common factors of 18 and 30


Find the greatest common factor of 18 and 30


Here is a link about Venn Diagrams.


This is a video about finding the greatest common factor between two numbers.

Probability

What we did today (01/28/11)

Question: p(of the product of two dice equaling an odd number.

Solution: Look at the side numbers and the top numbers. Multiply both numbers (e.g. for the first one - 1 x 1 = 1). After Multiplying, look at all the numbers and look for all the odd numbers.

Math notes! Write it down if you never got it or if you we're away.
