Use number recognition. Most kindergarten children know how to count to 100 by memory. However, it is just as important for each student to learn number recognition as well as the position of the number on the number line. The skill of number recognition should be practiced and mastered before the child moves to the next step.
Count by twos. After the child learns to recognize each number, have him count by two. Practice by counting from 2-100. Explain to the child, through the use of visuals, that counting by two is the same as counting "even numbers". Explain that objects that are even in number can be divided fairly, evenly between friends.
Introduce the concept of division. Yes, dividing is a concept that your kindergarteners should learn first and foremost. While this step does not refer to writing out a division problem, it does refer to teaching the child how to divide even numbers. After teaching problem solving situations, your kindergarten children will be ready to tackle other concepts in math.
Introduce the concept of addition. Use the aid of flannel boards and counting objects, to teach addition. When teaching a new addition to the class, ask the student if the answer is even or odd.
Introduce the concept of subtraction. Just as addition was made easy by the aid of flannel boards and counting objects, so should the concept of subtraction. When teaching a subtraction problem, use the words "take away from" and "minus". Explain to the children that both phrases mean the same thing. In subtraction, as well as addition, inquire if the answer is an even or odd number.
