Math Project Grade 6 Unit 2

A batting average is calculated from a ratio of a player’s hits to the number of bats. Batting averages are usually recorded as a decimal to thousandths place. The table below shows the batting results of three baseball players who received the Most Valuable Player award while playing the St. Louis Cardinals.  Express each batting average as a decimal to thousandths place and as a percent. Then based on your calculations what batting order would you put these three players.Explain your answer.

All work (calculations) must be displayed on 11 x 14 poster.

 Player Batting Results Albert Pujois (2008) 187 hits in 524 at bats Stan Musial (1948) 230 hits in 611 at bats Rogers Hornsby (1925) 203 hits in 504 at bats

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 fraction and percent  are correct. 10 points each  Total of 60 Batting order listed and explained 10 points each Capitalization and punctuation are correct, no spelling or grammatical errors 10 points

Note: 5 points will be taken off for each day it 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

Fractions

Find  a common denominator.

Keep the denominator the same

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

2/4 + ¼ = ¾

Subtracting

Find a common denominator.

Subtract  numerators

Keep the denominator the same

Example: ½ – ¼ =  ½ (2/2) = 2/4 – ¼

2/4 – ¼ =¼

Multiplying

Multiply the numerator by the numerator

Multiply denominator by the denominator.

Simplify product if possible.

Example: ½ x ¼ = ⅛

Division

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

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
