<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Are there any everyday ways to help my children become better math students? -- Wanting Mathematicians!</p>
<p>Answer: Believe it or not, the best way to help your children become better mathematicians is by having them do more math. For example, if their teachers assign only the odd problems in a textbook for homework, they should also do the even ones. And if a math assignment is a brief one, they or you can go online and look for similar work for them to do. You'll find an abundance of worksheets by both grade level and specific skills.</p>
<p>Also, there are many books that you can purchase that will give your children additional practice in the skills that they are working on in school. Just 15 minutes of extra math work several times a week will soon pay dividends. And your children will begin to feel greater confidence in their ability to do math.</p>
<p>Now, if your children's skills in math are a bit subpar, you need to do some detective work to discover what those specific areas are. Their teachers should be able to identify these areas for you through looking at classroom and standardized tests and recent schoolwork. Children are not going to become skilled mathematicians unless they have mastered earlier skills that they should have learned.</p>
<p>A steady diet of doing extra math is not likely to encourage students to really enjoy mathematics -- so intersperse fun activities in math. On our Dear Teacher website (DearTeacher.com), you will find lots of interesting things for them to do in Learning Activities: Math. In addition, children can learn how to do lightning-quick calculation and amazing number tricks in the book "Secrets of Mental Math" by Arthur Benjamin and Michael Shermer.</p>

<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>We are a card-playing family, from crazy eights to pinochle. All our children from 8 to 15 enjoy cards. We think card playing teaches them a lot. Are we right? -- Wondering</p>
<p>Answer: Learning to play cards has many different benefits for mathematical thinking and creativity. Here is a game for you:</p>
<p>Procedure: The object of this game is to combine the number values of the playing cards in any order using any operation to make the value of 100. The playing cards have been given these number values:</p>
<p>Ace (1), Kings (13), Queens (12), Jacks (11) and 2-10 (number value of the cards).</p>
<p>Shuffle the deck of playing cards. Start play by dealing yourself cards one at a time. Keep dealing cards until you can make the value of 100 out of the cards you have dealt. Try to make 100 using the fewest cards possible </p>
<p>To make 100 with the cards dealt, follow these rules:</p>
<ul>
<li>-Every card dealt must be used.</li>
<li>-The cards can be used in any order.</li>
<li>-Any operation can be used.<br />
</li>
</ul>
<p>For example, if the cards dealt are Jack, 10, 5 and 2, those cards can be arranged as follows to make 100:<br />
(Jack x 10) - (5 x 2) = (11 x 10) -10 = 110 -10 = 100 </p>
<p>Work through the entire deck of playing cards. If needed, turn the last card in the deck into a wild card (any number) to make the final 100.</p></div>

He panics before he even reads the problem because he feels there will be too many steps. How can I help him to feel better about taking math tests? -- Math Block</p>
<p><strong>Answer:</strong> Practice and more practice -- that is the key to every athlete's success and will also be the key to your son's success. You need to work problems with him daily up until the day of the test, and he should also work some on his own that you check over with him daily.</p>
<p>Teach him to carefully examine the information in a problem first. Have him make a list of the information that is known and what is unknown about the problem. Some children find it helpful to draw pictures or diagrams to show the facts and relationships of a problem. They should be thinking about whether they have solved similar problems and how they did them. You'll know that he understands a problem if he can retell it as a story.</p></div>

<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Question:</strong> While my children do all right in math in elementary school, they usually get just B's. I wonder if you have some tips that might help them get A grades. -- Seeking Help</p>
<p><strong>Answer:</strong> What you do to sharpen your children's math skills will depend on what grade they are in school. Since your children are already receiving good grades, slight tweaks could result in even better grades.</p>
<p>Our number one suggestion for helping children in elementary school is for them to neaten up their work if it is sloppy and causing errors to be made. Young children may need to work on the correct formation of numbers, while older students should make sure the numbers in problems are properly aligned. It also helps at this level to make manipulatives to use at home to reinforce basic concepts and to sing the basic math facts to make recalling them easier. In addition, there are a great number of websites that let children drill on the basic facts.</p>
<p>Students in middle school and high school may find it easier to solve word problems if they use smaller numbers in place of the actual numbers in a problem. It also helps if they underline the key facts in a problem and cross out unnecessary ones. They should also circle the question that they need to answer. And sometimes drawing a picture can help in solving problems.</p>
<p>When students take more advanced math classes, they may find it helpful to work with another student and keep formulas on a small card to trigger their memories.</p></div>

<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Question:</strong> Division is scarcely taught in my child's school. I'd like to teach her how to solve division using mental math. How should I do this? -- For Division</p>
<p><strong>Answer:</strong> Being able to handle division in your head is a worthwhile skill for both children and adults. Just think of being able to divide a restaurant bill between five people as an example. Or having your child be able to easily divide 100 marbles between nine children.</p>
<p>Start your child out with one-digit division using this technique advocated by Arthur Benjamin and Michael Shermer. The first step for your child is to figure out how many digits will be in the answer. For example, to solve 140 divided by 6, you would first determine that 140 lies between 6 x 10 = 60 and 6 x 100 = 600. So the answer will lie between 10 and 100 and will roughly be a two-digit number. The next step is to figure out the largest multiple of 10 that can be multiplied by 6 with an answer below 140. 6 x 20 = 120 and 6 x 100 = 600, so the answer must be in the 20s. Then the number 120 is subtracted from 140 to get 20. Now the actual division problem is 20 divided by 6. Since 6 x 3 = 18, which is 2 away from 20, you have the rest of the answer, which is 23 with a remainder of 2.</p>
<p>Becoming quick at mental division takes time. Your child will need to practice doing this with similar problems. Ultimately what is happening is that you are using the process of simplification to make the problem simpler. This method of mental division and easy tricks for adding, subtracting and multiplying are explained in the book "Secrets of Mental Math," by Arthur Benjamin and Michael Shermer. Using this book will turn your daughter into a math whiz in no time. Soon she'll be doing all kinds of calculations amazingly fast.</p></div>

<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Question:</strong> I'm going on 72 and somehow seem to have missed the lesson on dividing fractions. Oh, I know there are rules to follow, but I'm a visual person and I've forgotten the "rules." What I need is to be able to picture what is really happening in dividing fractions like 2/3 by 1/4. -- Still Learning</p>
<p><strong>Answer:</strong> No matter how old you are, math concepts are always a lot easier to understand when you can actually see how they work. The rule for division with fractions is to invert the divisor and multiply. To solve your problem, you simply need to multiply 2/3 by 4/1. The answer is 2 2/3. In order to picture how the problem is solved, however, you need to think of how many sets of 1/4 are in 2/3. To do this, both fractions have to be expressed in the same fractional parts.</p>
<p>In other words, how many sets of 3 (twelfths) are in 8 (twelfths)? Take a long strip of paper and draw lines to divide it into 12 equal parts. Then, cut one piece to represent 8 (twelfths) and another for 3 (twelfths). Determine how many sets of 3 (twelfths) are in 8 (twelfths). There will be 2 complete sets of 3 and a set of 2 thirds left over.</p></div>

<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p><strong>Question:</strong> I am appalled that my daughter's middle school math class is starting to play bridge during class time. Is there any academic value to this game, or is it just a waste of time? - Help me out</p>
<p><strong>Answer:</strong> The game of bridge is now invading classrooms across the country, even in elementary school. Your daughter can definitely benefit from learning this game. When bridge lessons are given as part of the regular school curriculum, teachers are impressed with the results. They see their students' thinking skills improving as they learn to look ahead and to plan and predict.</p>
<p>Bridge is not a waste of time in math classes, as it helps students with the areas of probability, ratios, percentages and fractions. It also develops their number sense. Plus, playing bridge has been shown to improve students' reading, comprehension and communication skills as well as to expand their vocabularies. You can also expect such immediate benefits for your daughter as improved memory, concentration and reasoning skills as well as the ability to work with others in solving problems.</p>
<p>Bridge appeals to students of all ages because it's a competitive activity. Students definitely get wrapped up in the competition while improving a great number of skills. Some even enter tournaments and win prizes. If you don't know how to play bridge, consider learning the game yourself so you can enjoy playing a few hands with your daughter.</p></div>
