Use this device as a visual aid to represent counting and simple math operations during place-value activities. Four labeled plastic cups denote place values from ones to thousands and are color-coded for easy recognition. Students rotate the nested cups to add, subtract, or expand large numbers into individual place values. The plus and minus signs are used for simple calculations, where turning cups counter-clockwise represents subtraction and turning them clockwise represents addition. Select the appropriate number of cups for different grade levels. Individual Kit includes 5 cups. Set includes 10 of each (50 cups total). Recommended for Elementary and up.
