This post is inspired by some recent experiences I’ve had tutoring bright children from top high schools and the utter shock I’ve experienced learning some of the things they DIDN’T know. I’m not talking about formulas like circumference that they could have forgotten or advanced topics like logarithms. I’m talking basic reading, writing, and arithmetic topics that they probably learned in grammar school.
When I bring this to the attention of these students’ parents, they are usually equally astounded and often think I’m joking. I’m not sure who’s to blame here, but regardless of which of their teachers failed to teach them certain fundamentals, it’s something that can (and SHOULD) be fixed. Immediately.
If you’re a parent or guardian or concerned older sibling reading this, go home and make sure your son or daughter (or brother/sister) knows these concepts.
1. 60% of 100 is 60.
Seems easy enough. Not to my students. I can’t tell you how many of my students don’t understand that when you take a “percent of 100,” it is equal to the number. This is a clear breakdown in the understanding of percents. If you simply explain that “per cent” actually means “out of 100,” then they’ll always know that 60% is 60, 25% is 25, and so on as so forth.
For a simple way to teach percents for standardized tests, try using the Percent Translation Method:
What –> n (or any variable)
Is –> =
% –> /100
of –> * (multiply)
You can easily translate ANY percent question: “80 is what percent of 400?” –> 80 = n/100 * 400, which then simplifies to:
80 = 400n/100 —> 80 = 4n —> n = 20
2. 25% is the same as 1/4.
Just like percents, fractions are ALL over standardized tests (and are necessary for basic life skills as well). Students should be able to understand what a fraction is and how it relates to a percent. They should also know how to represent fractional part in a chart or pie graph.
3. How to identify the subject of a sentence.
Forget prepositions, pronouns, and dangling modifiers. I’m talking SUBJECT and VERB. It’s shocking how many students cannot identify them in a sentence. A great exercise for students who struggle with this should be reading short newspaper or blog articles and going sentence by sentence circling the subject and underlining the verb.
In general the subject of a sentence is the person, place, or thing “doing” the action of the verb.
4. Perimeter of ANY shape = adding up all the sides.
The exact question was: If Jenny is fencing in a rectangular yard that measured 80 feet by 300 ft, what length of fence does Jenny need? My student was beyond baffled. She couldn’t decide whether to use the volume formula or area and then couldn’t remember the formulas.
When I told her she didn’t need a formula for this, just logic, she was perplexed. We talked through the problem together and she finally understood perimeter.
In order to help give students context of geometry, try talking to them about everyday things such as the area of a room versus the volume of water so that they are actually understanding formulas instead of memorizing them.
5. Money and Cards
Standardized tests often include questions about money and playing cards. I’m not kidding about this, but an AMERICAN student of mine did not know how many cents were in $1. This is not okay. Student should be learning about coins and money by the 3rd grade (let alone handling it on a daily basis).
This is also particularly important for international students looking to apply to US universities. Students living outside the US are obviously using a different currency, but the US-based standardized tests utilize US currency. Make sure your son/daughter knows the values of pennies, nickels, dimes, and quarters, and how many are in a dollar.
The other questions that frequently confuse students are those involving playing cards. Maybe with the advent of mobile games like Angry Birds and Words with Friends, people are playing fewer card games, but until the SAT starts asking about the number of levels in Angry Birds or the point value of a “J” in Words with Friends, students better know that:
1. There are four suits, 2 black, 2 red
2. Black suits: Clubs, Spades
3. Red suits: Hearts, Diamonds
4. 52 cards in a deck
5. 13 cards in a suit (52/4)
6. There is no #1 card and numbered cards go from 2-10
7. There are 4 “face” cards in each suit: Jack, Queen, King, Ace
While we’re on the subject of in-person games, they should also know that a die has six faces with 1-6 dots on each face.
I hope this helps and I hope it gives you the opportunity to teach your child some things and really help him or her out with the fundamentals.
