Number Flash vs Number Rack, by MLC

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.

Number Rack facilitates the natural development of children’s number sense. The movable, colored beads encourage learners to think in groups of fives and tens, helping them to explore and discover a variety of addition and subtraction strategies. This virtual version of the manipulative is an open-ended educational tool, ideal for elementary classrooms and other learning environments. FEATURES • Display 1 to 10 rows of beads, 10 beads per row. • Hide beads with resizable covers, which allows teachers or learners to model subtraction or difference problems. • Reverse the colors of rows 6 to 10 to distinguish (or not) groupings of 25 beads. • Use the drawing tools to annotate work and show understanding. • Add equations, expressions, and descriptions with the math text and writing tools. • Share work by saving an image or providing a share code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.
