Digi-Game

Description

Visit the robot factory where students will mix and match robot body parts to build their very own creation - one correct answer at a time! In this engaging and interactive digital game, students practise number formation skills by building the smallest possible two-digit number using a set of given digits.


Each question challenges students to think critically about place value. They are given three digits and must select the smallest two-digit number they can create using just two of the digits. With every correct answer, they unlock a new robot piece, getting closer to constructing a one-of-a-kind robot masterpiece.


Let's Build - Making the Smallest 2 Digit Number is a fantastic way to help students explore tens and ones, strengthen their understanding of number comparisons, and build number sense, all while enjoying a fun, hands-on digital experience.
