These activity sheets will give your kindergarten students practice in using grouping to add numbers.

How do you teach students to add groups of items? Counting is important because it enables children to learn the meaning behind the numbers. As adults, we automatically understand what six units of something mean, but children need a lot of practice to grasp this basic numeral concept. Counting as a task within itself is quite complicated, and there is no point in making it more complicated than it already is. So, here is a very easy and the best method to help you count a group of objects. Count objects by making groups of 10. First, pick out all the objects that can be counted in tens such as 1, 20, 30, and so on. Once this step is done, you can easily get the individual numbers in groups of ones such as 5 6 7 and so on. When you count numbers in organized groups of tens or ones, the counting becomes easier, and you can keep track of the numbers that you have counted. When you have no arrangement whatsoever, you can forget which number you were in, and that would cause you to start counting from one again.

This is the skill of picking out items or objects out of crowd and finding out how many of them are in the group. When you look at it they are two very different skills, but they gel well together. There are also additional skills that we work on in this section. The skills include: counting part of a group, counting singles and doubles in a mixed group, and recognizing and matching geometric shapes. These worksheets cover using grouping to add numbers together. Students will color simple pictures, then add the different groups together.

Adding Groups Together Lesson

Color any 3 balls blue and the remaining balls yellow. Now add the total number of balls and write the number inside the box. First we color any 3 balls with blue color. Now all the balls which have been left uncolored should be colored yellow. When all the balls have been colored, we count all the balls one by one. In the above question 3 balls will be colored blue and the remaining 5 balls will be colored yellow. When we count the total, it comes out to be 3 + 5 = 8. So we have to write 8 inside the box.
