This page contains a set of Base Nine blocks. Use the unit blocks from Material Card 4 with this set of Base Blocks. Cut along all solid line segments. Each piece is labeled. A Base Nine Long is 1 cm by 9 cm and is labeled "9L". The Base Nine Flat is 9 cm by 9 cm and is labeled "9F". Extra longs for Base Nine are on a separate Supplementary Material Card for Cards 12-15, found after Card 15.
