Really Good Stuff Daisy Number Sense Puzzles Set is a delightful way to engage our little learners aged 4 to 6 in the world of numbers! This interactive set not only fosters recognition of numbers 11 to 20 but also enhances subitizing skills through playful matching activities with tally marks, dice dots, and ten-frames. As parents and educators, we appreciate that these puzzles are self-checking, ensuring that our children build confidence in their math abilities independently. 4-6 years
