Magnetic place value cards (70 pieces) | descriptive blackboard material learning math school

This set contains 70 magnetic number cards (height 7.5 cm) made of 1 mm strong magnetic foil for use on steel boards or for the student's hand. Number representations or comparisons from 0 to 9,999,999 are possible. Packed in a box with instructions. - Can be ideally combined with our Dienes sets, place value plates and all other articles based on the place value principle - Realization that the position of a digit determines its value (principle of place value), structure of the decimal system, representation of numbers - Additive principle: The total value of the number results from the sum of the values of the individual digits. The number 486 is the sum of 400 + 80 + 6, Multiplicative Principle: Each digit in a number indicates how many bundles of that thickness there are. The 8 in the number 486 stands for eight bundles of ten, bundling principle: The decimal place value system is based on the basic number 10, i.e. ten elements of a unit are combined to form an element of the next larger unit. The values of the digits thus increase tenfold from right to left - Manufactured in Bensheim/Hessen/Germany.
