Build numbers 21-30 with this 2130-piece Numberblocks set. Includes 10 activity cards and character cards to reinforce learning through the popular TV series.

Review: Good for maths skills and imagination - Numberblocks fans here and always satisfied with their quality, although we have a few issues with number links- they are pretty fragile and so far we have 1 snapped from each set- Nr 14 and Nr 21. I wish they were made/ attachable in the same way as for those Numberblocks figures ( the ones as one piece from 1-14). Great that for each Numberblocks mathlink figure there is a separate card with visual instructions and that some cubes are attachable from 2 sides which makes more stable figures. My 3 y old's favorite from this set is 27 made as a cube and he knows that 3 x 9 makes 27
Review: Perfect. - Perfect, grandson loves them.

### ⭐⭐⭐⭐⭐ Perfect.
*by A***R on 27 December 2025*

Perfect, grandson loves them.

### ⭐⭐⭐⭐⭐ Links up to the episodes!
*by M***N on 14 October 2025*

These were perfect for helping my little boy learn maths. I like how the cards all link up to an episode of number blocks which allows them to see and do it at the same time. The blocks are also easy to put together and take apart and still hold together when the shapes are picked up. I think they are great value for money as they can be used for so many things.
