HABA Kullerbu Expansion Set - Columns - 10 Piece Set for Creating Higher Ball Track Layouts - 300850

• When your Kullerbu set is ready to grow upwards or in length then you generally need additional "construction material" in the form of columns, straight sections, curves and connecting elements. All this is included in the practical Kullerbu expansion sets. The columns bring height into play and are each provided with height indicators ... both as numbers and as dots. This set includes two 3's, two 4's, one 5 and one 6. Columns are made in Germany. Two 3's combined with a plastic sleeve is the same as one 6. Adding a 5 and a 6 makes 11…..and so on. Children are weaving early math skills into their building patterns. They learn problem solving skills troubleshooting layouts that don't work quite right and that makes success so much sweeter when the right combination is found! Intended for use with Kullerbu Base and Connectors #300849 and any Kullerbu track pieces and ramps (all sold separately). Putting together a dark green base, a column, and a light green connector results in a sturdy support for ramps, straight tracks, and curves. Younger children will usually need some help with the assembly, while older children can experiment by themselves with the various pieces and heights. Suitable for ages 2-8., Manufacturer: HABA
