Only Five - no more, no less - can stop the Numberblocks Express! Children join the number adventure and build their own train with this MathLink® Cubes Activity Set Numberblocks® Express Train. Based on the popular Numberblocks Express episode, children use MathLink Cubes in official Numberblocks colours to build a train as well as One to Five. Then they use the set’s 5 double-sided activity cards to complete 10 maths challenges to stop the Numberblocks Express. As they play, children practise counting, adding and subtracting, and more. Children can also watch the episode alongside to extend their learning.
