Sequences and Functions

In math we are learning about sequences and functions.  For example:   Input, x 1 2 3 4 x Output,  y   5 6 7 8 x + 4 When the input is 1, the output is 5.   After examining the pattern we can see that the output is always 4 more than the input.   Therefore:    output = input + 4      or      y = x + 4   What would the output be if the input was 12?

Red Ribbon Week

This week is Red Ribbon Week to remind kids to keep drugs out of their life!

Monday, October 22^nd                  Kick off Red Ribbon Week-Wear Red

Tuesday, October 23^rd             Team Up Against Drugs-Wear your favorite sport’s team shirt

Wednesday, October 24^th          Shade Out Drugs-Wear sunglasses

Thursday, October 25^th            Sock it to Drugs-Wear your craziest socks

Friday, October 26^th                Put a Cap on Drugs-Wear your favorite hat

In math we are learning about ratios, rates, and proportions.  For example: *If 15 students wear red on Monday and 9 wear another color, what is the ration or students wearing red to not wearing red?        The ratio is 15 to 9.  -->   (also written as 15:9 or 15/9)

*If a motorcycle travels 120 miles in 3 hours and a car travels 80 miles in 2 hours, are the vehicles traveling at proportional rates?

      _120 miles_ = _80 miles_           
          3 hours           2 hours

120 / 3 = 40 miles/hr and 80 / 2 = 40 miles/hr          YES

Mixed Numbers

We will be focusing on adding and subtracting mixed numbers and solving word problems.

You can help your student by pointing out situations where this skill could be used. 

 For example, Sam buys 9 1/2 ounces of popcorn at the movie theater.  During the movie he eats 5 3/4 ounces of popcorn.  How many ounces of popcorn were left over?

Adding and Subtracting Fractions

We will be focusing on fractions in math. This will include reducing fractions to their simplest form, comparing fractions, and adding and subtracting fractions with like and unlike denominators.

You can further this lesson at home by adding ingredients in a recipe book.

Example: 1/4 cup of sugar + 1/3 cup of flour

Rename: 1/4 = 3/12   and   1/3 = 4/12

Add: 3/12 cup + 4/12 cup = 7/12 cup ingredients

Decimals!

We will be focusing on comparing, rounding, adding, and subtracting decimals.  Make sure to line up the decimal points!

You can help your student by having them add prices when you go to the store.  For example, $3.99 for cereal + $4.29 for a gallon of milk.  Then subtract the total from a 10 dollar bill!

   3.99                         10.00

+ 4.29                      –   8.28

 $8.28 ßTotal            $1.72 ßChange

Multiples

We will be focusing on multiples, common multiples, and the lowest common multiple (LCM) this week. A multiple is the product of a number and any whole number.  For example, multiples of 3 would be 3, 6, 9, 12… (3x1, 3x2, 3x3, 3x4…)

Common multiples are multiples two numbers have in common.  For example, 12 is a common multiple of 3 and 6 because 3 x 4 = 12 and 6 x 2 = 12.

 

A card game can be played with 2, 3, 4, or 5 players and each player always has an equal number of cards.  What is the least number of cards that can be in the deck? (LCM)

Factors

We will be focusing on factors, common factors, and prime factorization this week.  A factor is a number that divides into a whole number with a remainder of 0.  For example, factors of 12 would be 1 and 12, 2 and 6, and 3 and 4 (1 x 12 = 12, 2 x 6 = 12, 3 x 4 = 12).

Real-life example: Sally made 15 sugar cookies and 24 chocolate cookies for the school bake sale.  She made packages of sugar cookies and packages of chocolate cookies, each with the same number of cookies.  How many cookies were in each package?

Factors of 15: 1, 3, 5, 15                              Common factor: 3
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

*She could put 3 cookies in each package.
