• The number is customisable: our digital stamp is customisable to design various mathematical problems, and has a gentle roll that can create at least 100 problems.
• Motivate logical thinking: this number teaching seal provides an interesting way to learn mathematical problems. It fulfils 1-100, which are shown in the chapter about teaching scroll numbers.
• Improve computing skills: Mathematical problems can be quickly scrolled through our addition and subtraction seal and it dries quickly. Your child will train their mathematical thinking skills by doing homework every day.
• Can be reused: the print is clear and the colour is difficult to fade after drying, which can be reused by adding new ink. The digital stamp for children contains a digital teaching seal and 1 bottle of ink.
