Tips to Teach Youngsters How to Subtract - Once children have mastered the concepts of addition, they are faced with a challenge of grasping the concepts of subtraction. Children often take up subtraction as the opposite of addition and try subtracting through addition. For example, children learn that 12+24=36 or 36 - 12=24. In this manner, children memorize the sums, but they cannot fully understand subtraction. Youngsters need to understand the concept first if they are to learn fully. Let's have a look at the fun ways to make children understand subtraction. DRAWING OBJECTS - Children learn better with visual representations. Employ this technique with subtraction sums. It is best if you draw the objects or provide them with the worksheets. Explain the given problem to the children. Ask them first to count the objects and then exclude the objects from the problem. Once you have subtracted the objects, prompt children to count the remaining objects. NUMBER LINE - Present your child with a number line ranging from 0 to 10. Recite the problem to the students. For example, if there are 9 cats in the pet store and 2 are adopted. How many are left? Put your pointer on 9 at the number line and move down two numbers to number 7. Ask your child how many cats are left. SUBTRACTION FACTS - You can also employ fact families to make your child learn subtraction. A fact family comprises a set of mathematical facts with the same numbers. In each fact family, there are three numbers. These numbers are added and subtracted in different ways. For example, 10-7=3 and10-3=7 These printable lessons and worksheets introduce students to the concept of subtraction.
