All official MLB baseballs are hand-stitched at the Rawlings factory in Costa Rica. No one has yet created a machine that can do it with the necessary precision. Each one has exactly 108 double stitches (216 in total).

Ok my fellow Senior Friends, who doesnโ€™t like to save some money ๐Ÿ’ต FYI EVERYONE!!! I heard a guy ask for his senior discount @ Wendy's, The girl at the register apologized and charged him less. When I asked the man what the discount was, he told me that seniors over age 55 ...get 10% off everything on the menu, every day. (But you need to ASK for your discount.) This incident prompted me to do some research, and I came across a list of restaurants, supermarkets, department stores, travel deals and other types of offers giving various discounts with different age requirements. I was actually surprised to see how many there are and how some of them start as young as 50. This list may not only be useful for you, but also friends and family, too. Dunkin Donuts gives FREE coffee to people over 55. If you're paying for a cup every day, you might want to start getting it FREE. YOU must ASK for your discount!

Community note
These โ€œdiscountsโ€ are suspect at best. Food Lion does not offer a discount. Stein Mart is out of business. For a more accurate list: caring.com/resources/seniโ€ฆ

Certain problem types beg for a distance interpretation. Similarly, certain numbers in relationships beg for a distance interpretation. Finding the Distance/Difference is an important strategy for subtraction. Read More in the K-2 specific DMR book: na2.hubs.ly/H029K8t0

I was wrong in my last video. Today, I learned that "minus" is a preposition and NOT a verb???

When you believe ability is fixed, you create systems that sort students. When you believe ability is developed, you create systems that teach students.
