This chart is thickly laminated and is printed on premium glossy (200 g) UV resistant paper and comes with 2 sided lamination (125 micron, 5.0 Mil) and metal eyelets to make the chart easy to display. It comes in a convenient poster size 50 x 67 cm (20x26'') and can be written on and wiped off with non permanent markers. The 125 micron lamination ensures the chart does not curl up at the edges and the UV treatment ensures the chart does not get a faded yellow color over time. The terminology is in English or Latin.
Abacus with 5 columns that represent units, tens, hundreds, thousands and ten thousands. You can use both sides (one with labels). Suitable from counting until addition and subtraction. Easy for teaching analysis of numbers in the decimal system, and also to demonstrate the principle of ‘borrowing’ from the next column. You can appear to the students only the beads that you are using. You can order the ababus on base with wheels.
