Kids will have fun practicing place value skills as they try to unlock the phone. Even more challenging for upper grades they will need to understand decimal place values. Some introductory pages to the human body for first and second graders. Creative and artistical mapping skills are required for kids to layout and build their own rooms - excellent math practice. Finally, lots of technology and programming practice with some simple operations - including multiplication and division which use different symbols in most programming languages. All in all, kids will love working on this STEAM book.
