Topics for Quiz Chapter 2.1 to 2.4 Wednesday October 23

There were several methods introduced for the skills. Students can choose any method. However the following are suggested methods:

 2.1 To change a decimal to a fraction use place value and simplify

       To change fractions to decimals use division

2.2 to order fractions and decimals convert to one form and compare. Use methods above.

2.3 Follow methods on pages 81 and 82

2.4 multiply fractions then simplify or simplify before multiplying (crossing out method).

Math Project Grade 6 Unit 1

A company sells Apple Cherry Mix. They make large batches of the mix to fill 250 bags each. Determine how many pounds of each ingredient should be used to make one batch (250 bags) of Apple Cherry Mix. Then decide how much the company should charge for each bag of Apple Cherry Mix and explain your decision. All work (calculations) must be displayed on 11 x 14 poster.



Important Facts

Ingredients in Apple Cherry Mix (1 bag)

¾ pound of dried apples

½ pound of dried cherries

¼ pound of walnuts


Cost of the Ingredients

Dried apples: $2.80 per pound

Dried cherries: $4.48 per pound
Walnuts: $3.96 per pound


Below is a breakdown of grading guidelines:


Poster is neat and colorful 10 points
11 x 14 Poster is used 10 points
All calculations for each ingredient are correct 30 points
All calculations for the price of each bag is correct (there is a profit)  

40 points

Capitalization and punctuation are correct, no spelling or grammatical errors 10 points

Note: 5 points will be taken off the grade each day the project is late.




Topics for the future


Chapter 5

Change percent to fractions

Write number over 100 reduce to simplest form

Note: if numerator has a decimal then multiply the numerator and denominator by the same power of ten to get whole number for numerator, then put in simplest form

(see page 275)


Change percent to a decimal

Write number over 100 (fraction), divide numerator by denominator

(see page 276)


Change  fractions to a percent  

multiply the numerator and denominator by the same number to get a 100 in the denominator.

Write the numerator with the percent sign

See page 281

Note: if the denominator can not be multiplied to get a 100, change to decimal than a percent


Change decimal to percent

Multiply the decimal number by 100 add percent sign

See page 281


Change  fractions to decimals

Divide numerator by denominator


Change decimal to fractions

Write the number as a whole number in the numerator

Write the place value as the denominator

See top of page 282

Fractions Chapter 2



Find  a common denominator.

Add the numerators.

Keep the denominator the same

For example: ½ + ¼ =  ½ (2/2) = 2/4 + ¼

2/4 + ¼ = ¾



Find a common denominator.

Subtract  numerators

Keep the denominator the same

Example: ½ – ¼ =  ½ (2/2) = 2/4 – ¼

2/4 – ¼ =¼



Multiply the numerator by the numerator

Multiply denominator by the denominator.

Simplify product if possible.

Example: ½ x ¼ = ⅛



Use the formula Keep Change Flip (KCF)

Keep the Dividend change the division sign to a multiplication sign and flip the divisor.

Example:    ½ divided by ¼

               = ½ x 4/1

               = 4/2 or 2



Sept. 27, 2018 Chapter 1

For adding and subtracting Decimals:

  1. Align the numbers so that the decimals are arranged in a vertical line (one on top of the other)
  2. Perform operation add or subtract


For multiplying decimals:

  1. Multiply the  numbers without the decimals
  2. Count the number of digits after the decimal in both factors.
  3. Place the decimal in the product by counting back (right to left) the number of digits counted in step 2.


For division of a decimal by a whole number:

  1. Place the decimal point in the quotient directly above the decimal point in the dividend
  2. Divide the numbers


Divide decimals when the divisor has a decimal:

  1. Rewrite the divisor as a whole number
  2. Whatever we do to the divisor we do to the dividend
  3. Place the decimal in the quotient
  4. Divide
