Addition and Subtraction

Addition
Learning about addition is among the first basic knowledge that children should have.
This is the virtual activity (addition games)that I have found interesting to create more understanding and improve children’s skills in solving addition process.
Subtraction
Learning about addition always come with learning on subtraction. If “increase” and “add” is the key words of addition process, in contrast, in subtraction,the concepts that children need to understand is about the number “decrease” and “become less”
