Whether you call it math or maths, mathematics is fun! Just like our Alphabet Blocks, Math Blocks come 10 to a set in their own pure linen sack. Symbols include: – the numbers 0–9 each repeated four times – basic math symbols: +, -, x, ÷, =, % – punctuation symbols: @, #, &, !, ? – 4 emojis plus a rainbow, a sun, a moon, a star and a heart The Math Blocks can also be used as a simple calendar system for your shelf or combine them with our Alphabet Blocks to make plenty of new messages. #wow:) Material: Wood Blocks Size: 5,5 cm x 5,5 cm x 5,5 cm  / 2.1 x 2.1 x 2.1 in. (each) Sack Size: 32 cm x 32 cm / 12.6 x 12.6 in. Care: The blocks are made of solid wood without any treatment. You can remove general grime by wiping the blocks with a damp cloth. However, if the blocks get dunked in watercolour or meat stew, those stains will be difficult to remove. The sack is a different matter. You can throw it in the wash and be merciless with it. The flax linen can take a lot of abuse.
