name-collectin boxes

Today I introduced name-collection boxes. Basically, they are used to collect equivalent names for numbers. It offers a simple way for children to experience the powerful notion that numbers can be expressed in many different ways. A name-collection box is an open-top box with a label attached to it. The name on the label identifies the number whose names are collected in the box. The box shown above was a 10-box, a name collection box for the number 10. Names can introduce sums, differences, words in English or another language, tally marks, Roman numerals, money and so on. We had a lot of fun with this...and even learned a few numbers in Chinese!
