Methods for Teaching Students Simple Addition - Learning addition comes after children have firmly grasped the concepts of counting. But before children start performing addition sums, they should be clear about the nature of addition. A variety of teaching techniques and tools can be helpful in effectively teaching addition to your children. Below we have discussed a few methods of helping your child learn addition USE DIFFERENT OBJECTS - Children easily and quickly grasp the concepts that are demonstrated with tools and objects children tend to have a quicker response time towards visual tools. Use easy-to-handle objects for teaching purposes like block and beads. Give your child small groups of items and ask him to merge the groups. Prompt him to count the total number of the combined large group. Explain that combining two groups meant that he had added them together. EMPLOY DIFFERENT GAMES - You can use different games to encourage learning addition in a fun way. Ask your child to roll two dices and ask him to add the results of both the rolled dices. Make it a bit challenging by employing mire than two dices, or you can also use dominoes and cards to practice addition. MEMORIZING DOUBLES - Memorizing doubles can be helpful for your children when they start doing longer and complicated additions. Doubles mean math facts like 2+2=4 or 5+5=10 These doubles are the reference points for the students when they start learning addition. For example, a child who knows that 5+5=10 can quickly calculate the sum of 5+6=11, by simply totaling one to the sums. These worksheets help students learn how to add an additional unit to the whole and start to introduce preschoolers to addition.
