F.U.N. stands for Fluency & Understanding Numbers.
This versatile, open number line provides a visual representation for a wide variety of concepts. The Number Line System includes a double-sided, writeon/ wipe-off number line (in two 6" x 40" sections) with a blank line on one side and a line with tick marks on the other.
Also included are magnetic hooks to attach number lines to white boards, binder clips to affix cards, and links to attach cards together to show equivalency.
The Grade-level Card Sets feature a comprehensive activity guide and hundreds of cards with numbers, words, symbols, fractions and more to be placed on the number line.
