These inviting number stackers will be a valuable resource to teach early number concepts, by helping children to make connections within and between numbers to ten. The bases measure 2" and show four different representations for each number: numeral, standard 1-5 dice array, random dot array and 10-frame pattern. Ideal to support early number sense and counting, children will be able to clearly see the quantity or 'howmanyness' of each number, subitise through different patterns, 1:1 counting, 1 more/1 less and difference. Made from responsibly sourced beech wood, each set includes ten number posts (2.5"-7") and 55 rings. Age 18 months and up. Recommended age 18+ months
