1. Testing is Good!
When they hear the word “test”, most students react with angst and dread. Who wants to take a test? Well, mostly nobody. But did you know that testing is the best way of learning? According to Drs. Barbara Oakley and Terry Sejnowski, testing is better than re-reading.
Often, closing the book and testing yourself on whether you can solve the problem or recall the information you think you understand, will speed up your learning at this stage. You often realize the first time you actually understand something is when you can actually do it yourself. Actively recalling information is a great way to burn it into long-term memory.
2. Start Early
The simplest way to improve test results is to start studying well ahead of time. This will get material into your long-term memory, where it has staying power. But don’t try to do it all at once. Instead, break studying down into manageable pieces. And then use the spaced learning technique: review it the next day, and then a few days later and so on. Another value of starting early is to find out whether you need help before it’s too late.
3. Understand the Test
Ever studied the wrong material or missed a key section? There’s an easy way to prevent this: Ask your teacher for guidance, or for standardized test, find out what material they cover in the tests. Create a table of contents for what you think will be covered in the test and then find out:
Fashion designers use a lot of math. They use addition and subtraction to find out if they will make a profit on the clothes they make. The profit on a piece of clothing is the amount of money earned from selling it minus all the costs of making it. For example, let’s say a designer makes a dress. She buys the fabric for $70.00.
Let's say, that the zipper costs her $5.00. She buys the thread for $3.00. She pays someone $40.00 to sew the dress. The designer uses addition to find out how much it cost her to make the dress: $70.00 + $5.00 + $3.00 + 40.00 = $118.00 The dress cost the designer $118.00 to make. Now suppose she sells the dress for $160.00. She uses subtraction to calculate her profit. She subtracts her costs from the amount she received: $160.00 – $118.00 = $42.00 So, the designer made a profit of $42.00 on the dress.
What happens if the collar is too wide? Shirt collars often have a thin strip of fabric around the edge for decoration. After making the collar, the designer notices that the strip is too wide. She must cut off some fabric from the strip. But how much?
The designer can use fractions to figure this out. She looks at her sketch and sees that the strip should be 3/8 inches wide. She measures the strip. It is 7/8 inches wide. So she must subtract the fractions:
7/8 - 3/8 = 4/8 which 1/2 inch. So she must cut 1/2 an inch of the fabric.
Two figures are congruent, when you place one over the other, the first one exactly covers the second. They have the same shape and size.
Congruent figures can make clothing interesting.
Look at the skirt shown above. It has small triangles on it. The designer made sure that all the triangles have the same size and shape. That makes the skirt pleasing to the eye.
You may not know it but knitting is very popular, especially among adult women. According to the Craft Yarn Council, 29 million, or nearly one-fifth of American women knit, and they make up 70 percent of all knitters.
According to Prof. Gresalfi, founder of KnitLab, knitting and its cousin crochet, are activities inherently filled with “rich mathematical thinking and problem solving.” One of the objectives of the KnitLab is to raise awareness that knitting is math.
How can knitting be similar to math?
A mathematician, artist and lecturer at the Cornell University, Daina Taimiņa, used a crochet hook, bright crochets and visualized very complicated mathematical concepts were only understood by highly experienced mathematicians. Using crochets, Daina has created a new way of understanding hyperbolic planes and has created a simpler way for the students to master it. Why do we care about hyperbolic plane?
An interesting story in the Harvard Gazette profiles Eni Dervishi’s journey from Albania to Harvard that began with two simple words: "table" and "chair". Fascinated by language, Eni, soon developed a passion for learning languages.
“I fell in love with languages,” she said. “Through languages I was able to see a different world. It opened my imagination to what was out there.”
Eni is from a small town in Albania. Her father had no formal education. Neither did her mother, though she returned to school as an adult. Her mother had to balance both school and house work and showed Eni with her actions that education is important.
Eni's small-town high school had no one to guide her in the application process. “My teachers hadn’t written letters of recommendation before,” she said. “I had to teach them.” When she needed to send official documents, such as transcripts, she found another hurdle. “I thought of faxing them, but there was no fax machine in my hometown.”
Despite these odds, Eni persevered and got accepted at Harvard. As you can see, Eni is from a modest background and did not have to climb Mount Everest, or take several extra co-curricular classes, or be a team captain, or, well, impress people. She followed her passion for learning languages. In addition to English, she learned some French,

Tips for Choosing the Best Summer Camp for Your Child
For parents, choosing the right summer camp for your child is just as important as picking the right daycare center, school, or club. It’s a decision that deserves some research, thought, and planning. Though there are hundreds of summer camps across the U.S., there may only be a handful of camps in your vicinity that are right for your child. Here are some tips to make sure you choose the right summer camp.
Involve your child in the process
Ultimately you have the final say on where your child goes for summer camp, but there’s a greater chance that they’ll have a fun, productive time if they play some role in the decision-making process.
The three major choices you have when picking a summer camp are sleepaway vs. day camp, long distance or close to home, and specialty or general interest. Ask your child if they feel ready to attend a camp that’s 24/7 or one’s that’s further away from home. Don’t push it, but encourage your child to step outside their comfort zone. If your child is super into a certain sport, activity, or field of study, you may want to consider a specialty camp. If not, a general interest camp might make them feel more comfortable.
“Be certain to include your child in the decision-making process. Together with your child, explore the camp options and examine the materials the camps provide … As children become better acquainted with the camp experience and more involved in the decision-making process, they will have less anxiety about going away to camp,” suggests the American Camp Association.
How to spot good and bad camps
What are the attributes of a good summer camp? First and foremost, the camp will have a focused curriculum. You’re not paying a camp to just send your kids out to wander aimlessly in the woods. You want them to learn and to experience interesting things. A good camp will have low staff turnover and will have some sort of positive presence - whether that be online or via the recommendations of friends and neighbors.
