This interactive Flash applet helps students develop the concept of equal groups as a foundation for multiplication and division. The applet displays an array of dots, some of which are covered by a card. Student use the visible number of rows and columns to determine the total number of dots. Clicking on the card reveals the full array, and a voice announces the total.

This resource is included in the following PD Collection(s):
Rectangular ArraysThis collection includes resources for introducing both discrete (separate objects) and continuous (area model) arrays to young learners. The resources provide suggestions about how to use arrays to introduce students to ways of organizing collections of objects, to repeated addition, to multiplication, to factorization, and to area. Helping young learners to develop a deep understanding of the characteristics of arrays will provide the foundations they will use when learning about multiplication and division, area measurement, and fractions.

      Lacks support for the learner

    • The applet provides no directions, runs too quickly, and does not take and respond to student input - thus, it depends heavily on mediation from another person. It also misses the opportunity to practice subtraction along with multiplication.
