This product is meant to be part of a quick number sense review/routine. It can be used at the beginning or end of any math lesson as a warm up or a review. Students view an "image" for several seconds (up to 5) and then the image is covered. The teacher asks students how many they saw and students tell how many. The image is uncovered again for several seconds and students can revise their answers. They then explain how they knew. One student may say he saw four on the top and four on the bottom. Another student may have counted by 2's. Another student may say there were two "missing". The objective is to get students subitising (recognizing the number in a small group without individually counting) and to practice early addition facts.
Each slide has a different image. The revealer tool is used to cover the images. For teacher use only, there are slides separating each number. For example, there is a "three" slide separating the images that show three. In order to use this with your class, I recommend pulling the slides you want to use to the top each day. The entire set is not meant to be used at once.
In kindergarten, you may use 5-6 images a day showing a single number and discuss how the number didn't change with the placement of the dots. Or you may show two numbers that are similar and discuss how (ex. five and six--there is one more dot showing).
If working on combinations to ten you could show fact families: six dots and four spaces and then four dots and six spaces.
In first and second grade, this is great way to practice addition facts and fact families as well as to reinforce number sense.
Teen numbers and numbers without the tens frame are also included.
