Table of 84

Introduction:

While memorising the multiplication table is an important foundation for learning maths, it is not the only factor that contributes to a child's success in maths. A hands-on approach to learning maths, which involves using various methods to help children do maths in real life, is considered more effective in helping children connect numbers and understand the basic rules of multiplication.

Studies have shown that children who learn maths in a hands-on way are more likely to retain what they learn and to develop a deeper understanding of mathematical concepts. This is because hands-on learning allows children to see the real-world applications of maths and to understand how mathematical concepts are used in everyday life.

For example, children who learn maths through cooking or baking can see how maths is used to measure ingredients, calculate cooking times, and adjust recipes. Similarly, children who learn maths through building or construction projects can see how maths is used to measure distances, calculate angles, and solve real-world problems. By using a hands-on approach to learning maths, children can develop a strong foundation in maths and build the skills and confidence they need to succeed in school and in life.

Why Is Multiplication Important?

While it is true that calculators can make math calculations easier, mastering multiplication tables is still a crucial skill for children to develop. The ability to quickly and accurately perform basic arithmetic calculations is essential in many areas of life, from making purchases to calculating time and distance.

Moreover, mathematics is a fundamental subject that forms the basis for many other fields of study, such as science and engineering. A strong understanding of multiplication and other mathematical concepts can help children develop problem-solving skills and logical thinking, which can be applied to a variety of real-world situations.

By introducing multiplication tables early in a child's education, parents and teachers can help lay a strong foundation for future academic and personal success. Mastering multiplication tables can instil a sense of independence and self-confidence in children, as they become more capable of solving problems on their own without relying on technology.

In addition to the practical benefits, learning multiplication tables can also have positive cognitive effects on children's brains. Regular practice with multiplication can improve memory, attention, and critical thinking skills, which can enhance overall academic performance and boost children's self-esteem.

Overall, mastering multiplication tables is an important part of a well-rounded education and can benefit children in many ways both in and outside of the classroom.

Benefit of Learning Table:

Learning the multiplication table is crucial for children to perform various maths calculations quickly and easily. It provides a strong foundation in maths that helps children at every stage of their education and beyond. For instance, to solve word problems, children need to have a good understanding of multiplication and the tables.

The importance of multiplication is highlighted in the mathematics curriculum for Key Stage 1, where children are expected to remember multiplication and division facts by 2, 5, and 10 and use them to solve simple problems.

In addition, schools often test children's knowledge of multiplication tables, and in 2018, the multiplication table test was introduced for fourth graders. It is recommended that children should be able to memorise multiplication tables up to 12x12 by this stage.

The multiplication table is not just important for basic arithmetic but also plays a vital role in higher learning, such as length multiplication, length division, fractions, and logarithms. Understanding fractions and fractions of numbers requires a good knowledge of the multiplication table.

Furthermore, the multiplication table is used in everyday life, such as calculating discounts, counting time, increasing the number of ingredients in a recipe, and planning a party. Children can't always rely on calculators, so memorising the multiplication table is essential.

In summary, memorising the multiplication table is an essential component of a child's education that helps build their confidence, independence, and cognitive function. It is a fundamental skill that will help them in their academic and personal lives, and it is essential to master it.

5 solved problems:

Q1. Ram plays 5 games in a day. How many games will he play in 84 days?

Ans: Number of games Ram plays in a day = 5

In 84 days Ram will play = 84 x 5

In 84 days Ram will play = 420 games

Q2. What is the value of 84 times 4 added to 200?

Ans. From the table,

84 times 4 = 84 × 4 = 336

84 times 4 added to 200 = 336 +200

84 times 4 added to 200 = 536

Q3. Solve 84 times 19 using the table of 84 minus 200.

Ans. 84 times 19 = 84 × 19 = 1596

84 times 19 minus 200 = 1596-200= 1396

Q4. Aman completes 7 assignments in a day. In 84 days, how many assignments will he complete?

Ans. Assignments completed by Aman in a day = 7

Assignments Aman will complete in 84 days =

84 x 7 = 588

Q5. A teacher charges Rs. 84 per hour for special classes. How much does she charge for 15 hours of this special class?

Ans. Charge per one hour = Rs. 84 Charge for 15 hours = Rs.84 × 15 Using the table of 84, 84 × 15 = 1260
