MATH TRAIL # 6

 

At this station you will learn about money and use decimals and decimal points  to show value.  A decimal is a special way of writing a number that is not a whole number - a number that is a part of some larger number.  The decimal system uses the place value system and a decimal point to assign values to numerals and to show the value of the whole.  A decimal is  really just another way of writing a fraction.  In a fraction, the denominator, or the part that tells how many it takes to make the  whole,  can always change, like 1/5 or 1/7 or 1/2.  In a decimal, the denominator is always 10 or a multiple of ten - 10, 100, 1000 and so on.  The denominator, or the number of parts it takes to make the whole number,  is determined by the place value of the number you are evaluating.   A decimal is  a fraction (a comparison of the part to the whole) but is written using a  decimal point  - .1, .05 or .023, as examples.   The most common use of decimals in numbers is to describe amounts of money.  There are 100 pennies in a whole dollar and it  is written like this -  1.00 or $1.00.

           

YOUR TASK:

 

Your task is to find your favorite seat in the cafeteria, smell the wonderful smells of school  lunches, hear  your stomach growling and solve these word problems.  You may use a calculator if you wish or you can use brain power.  Make sure to show your work,  record your answers,  and use this handy menu!

 

 

 

 

Problem # 1:

There are 437 students eating a student lunch today at Double Churches School.  A regular school lunch costs $1.10.  How much money should the cafeteria receive for student lunches today?

 

 

Problem # 2:

At  Kyle’s school in Tucson, Arizona, the student school lunch costs $3.36.  When Kyle buys his lunch he hands the cashier  a ten-dollar bill.  How much change should Kyle receive from the cashier?  How much change would Chelsey, a student at Double Churches get if she bought a student school lunch  at Double Churches and paid with the same amount?

 

 

Problem # 3:

Merideth, a student at Double Churches, is rather picky about what she eats.  However, this month she likes most of the menu selections and decides to buy her lunch for the entire week!  How much money will she need to bring on Monday to pay for her lunches for the week?

 

Problem # 4:

Seth, a kindergartner at Double Churches, is an even more picky  eater than Merideth and does not like to buy the whole lunch tray.  He would rather buy “a la carte” which in French means “from the cart.”  He buys the same thing every day:  milk,  hamburger and fries.  How much money does  Seth need to bring for lunch each day?

 

Problem #5:

Mrs. Poundcake is a rather plump, but happy, 4th grade teacher at Double Churches.  Everyday she drinks a chocolate SlimfastÓ shake with the other teachers and buys a glass of ice water.  Today, is Mrs. Poundcake’s   birthday, and her husband is going to eat lunch with her and her son, who is in the 6th grade.  How much will Mr. Poundcake pay for all three lunches today?
