Multi & single roller blinds

More and Less Rollers

The more and less rollers are sensory and educational toys, handmade and 3D-printed in Belgium by Play This Way. This set of 4 rollers is specially designed for use with playdough or kinetic sand and helps children aged 4 and up playfully master the concept of "one more, one less."

Roll each roller into clay or kinetic sand and discover a sequence of sums: two "more" rollers (with a little bear) show +1 sums, two "less" rollers (with a little butterfly) show -1 sums. Inside each hollow roller are 5 hidden discs with the corresponding answers — your child first rolls out the sum in the sand and then presses the correct answer disc next to it to check the sum.

Contents
Set of 4 rollers, each with 5 answer discs hidden inside (20 discs in total):

2 "more" rollers with bear icon — +1 sums (addition, "one more")
2 "less" rollers with butterfly icon — -1 sums (subtraction, "one less")
5 answer discs per roller, to imprint the answer in the sand
