![]() In addition to multiple-choice questions, there’s likely to be one or more open-ended math questions, a new trend in testing designed to assess reasoning and problem-solving skills. As a result, teachers must make sure they have at least touched on all the math topics that may appear on the test, even if they don’t have time to teach the topic fully until afterward. The challenge is that the tests are usually administered in the early spring to give time for results to be returned to the schools before the school year ends. These exams, which vary by state, are designed to make sure schools are meeting curriculum standards at performance levels set by the states. No Child Left Behind requires states to test students beginning in the 3rd grade in math and language arts. Nationwide standardized testing also begins in earnest in the 3rd grade. If John wakes up at 7:15, how much time does he have to get ready? This requires good computation skills, facility with telling time, and number sense. For example, a problem might read: The bus comes at 8:34. They also have to learn to tell time to the nearest minute, and to calculate elapsed time in minutes. Again, memorization is required for kids to learn to recognize a variety of complex shapes and angles. Geometry and measurement can also be challenging. This enables children to add, subtract, multiply, and divide money sums. Decimals are also introduced, along with the idea that fractions and decimals can represent the same concept - the part of a whole. Still, with time and practice, they come to understand that 1/2 of a pizza is the same as 2/4 of a pizza, and they learn to add and subtract simple fractions in the same fraction family. Teachers have a variety of acronyms to help students remember the steps, such as DMSCB, “Does McDonald's Sell CheeseBurgers?”įractions are another challenging area for 8-year-olds to master. This requires children to remember several steps in a certain order: Divide, Multiply, Subtract, Check, and Bring Down. Memorizing multiplication and division facts paves the way for the introduction of long division, where a two- or three-digit number is divided by a one-digit number. Teachers also share number tricks that work for multiplication as well as division, such as the fact that the sum of the digits in the answers to the 9 times table always equals 9. Learning to recognize fact families - groups of numbers such as 4, 3, and 12 that create multiplication and division facts in a certain order - can help a child’s facility with calculations. As with multiplication, division facts have to be committed to memory with the aid of worksheets, flash cards, songs, and rhymes. Understanding the concept behind division can be even harder for kids. And it’s necessary for children to understand multiplication and division thoroughly before they attempt to do it. ![]() This may seem obvious to you, but probably won’t be to your child. The best way to begin teaching multiplication and division is with visual representation - for example, 3 groups of 2 blocks, 4 rows of 5 students, 6 cups with 3 chips each. ![]() Much time will be spent making sure children understand the concepts of multiplication and division, and committing the 10 times tables and corresponding division facts to memory. Your child will learn how to multiply and divide, essential skills that are the foundation for virtually all future learning with numbers.
