Some students had trouble accessing the website last week, so they are included in the blog.

While we need to improve our pitching, the Orioles also have a weakness in hitting.
Currently, the O’s are 26th out of 30 major league baseball teams in batting average. If the team has 122 hits in 542 at bats, what is the team batting average?
No problems for April 22, 2010. This problem is worth 20 points altogether!

These eleven baseball players are often considered the greatest hitters of all time.
1. Copy and paste the chart into Excel. Change the font color to black if necessary.
2. Calculate the batting averages of the players.
3. Calculate the “Little Slugging Factor”. This is found my multiplying the batting average × RBIs × Home runs ÷ 100000
4. Sort the players by “Little Slugging Factor”. Email me your spreadsheet.
5. DOUBLE BONUS! Find another player, either current or recently retired, that has a high enough LSF to make the top five on this list and prove it in your spreadsheet.
Player: Games, At Bats, Hits, Runs Batted In (RBI), Home Runs
Hank Aaron 3298 12364 3771 2297 755
Rod Carew 2469 9315 3053 1015 92
Ty Cobb 3034 11429 4191 1961 118
Lou Gehrig 2164 8001 2721 1990 493
Rogers Hornsby 2259 8173 2930 1584 301
Reggie Jackson 2820 9864 2584 1702 563
Mickey Mantle 2401 8102 2415 1509 536
Willie Mays 2992 10881 3283 1903 660
Stan Musial 3026 10972 3630 1951 475
Babe Ruth 2503 8399 2873 2211 714
Ted Williams 2292 7706 2654 1839 521

Math Awareness Month
April is Math Awareness Month, and this year's theme is sports. Students are completing daily problems based on this theme at http://calvertschoolweb.org/wlittle/math_Awareness_Month_2010_DailyProblems.htm. The students are also completing specially designed activities in math class. These activites connect mathematics with one of their either history or English, and tie into the theme of Math and Sports. These can be viewed at http://calvertschoolweb.org/wlittle/Math_awareness_month_2010.htm.
MathCounts Competition
Calvert School's MathCounts team competed in February against schools from all over the Baltimore Metro and Chesapeake Bay areas. While we did not place in the top 6 this year, I am still proud of our team. The students who completed include Giorgio Caturegli, Dale Waters (top scoring team member!), Eddie Van Dyke, Alice White, Kendall Reitz, and Anna Dorsey.

Problems of the Month--January 2010
A Look At The Past Decade – The Problems
January 04, 2010
2010 is the start of a new decade, so here are a few New Year's problems.
1. At the start of the last decade everyone was concerned about Y2K... Well, we made it. Y2K was here and gone with no major problems. Interesting thing about the first date of the new millennium, 01/01/00 - when the digits of that date are added, it's the smallest possible sum of any date. What date during the next century, when written in that form, will have the greatest possible sum of its digits?
2. This New Year's date, 01/01/10, has a sum of digits equal to three. Find ten dates with the same sum of digits.
3. How many seconds will occur this millennium (the year 2000 through the year 2999)? Express your answer in scientific notation.
4. New Year's eve is a time when many people make resolutions...
Kaitlyn decided that she would like to read more during 2010, so she made a resolution to read 30 minutes each day. If Kaitlyn reads an average of 1 page every 2 minutes and she finishes her 6th book at the end of her reading session on March 31, 2010, what would be the average number of pages per book for these six books?
5. Nora’s resolution is to get more exercise. She decided that starting with the first full week in 2010, she will do a 45-minute workout four times each week (four days during every seven-day period). This means she will have to exercise four of the days during the week of Jan. 1 through Jan. 7, and then four of the days during the week of Jan. 8 through Jan. 14, and so on. If Nora sticks to her resolution, what is the first possible date on which she could reach a total of 25 hours of exercise for the year?
