Helps children transition from counting to number understanding. Watch a video demonstration of Number Flash in action: http://studysmart.com/www.studysmart.com/VideoBankUsinNumberFlash.html A ten frame with dots flashes on the screen (you can choose the number of seconds it appears on the screen). Then the ten frame disappears. Children need to choose the number of dots they saw in the ten frame. They can’t count because the picture has disappeared. This coaxes them to think of a number of objects in relation to five and ten. This helps children to use strategies to learn basic facts. Kindergarten and 1st Grade Teachers: Project Number Flash on a projector. Have all the students answer with pencil and paper at their seats.

This program teaches students to make words from letters and then to make sentences from words. The student first sees the letters of a word in their correct order. The student then moves the letters into spaces provided to form the word. The student next sees the letters “scrambled,” i.e. in random disorder. The student then puts the letters in order in the spaces provided to form the word. After that, the student sees scrambled letters with distracters, and must choose correct letter in the correct order to make the word. This program contains 24 chapters. Subject This program uses five items to teach words and sentence formation. These are Boy, Girl, Ball, Cup, and Dog. Click on the subject to use in the “Sentence Maker” program. Introduction This program always begins with the Introduction Screen. The Introduction Screen shows the subject(s) (Boy, Girl, Ball, Cup, or Dog) that will be used in the chapter and indicates what activity will be followed in this chapter.
